The first option is to have one computer for each student, interconnected through a local area network, facilitating information exchange and collaboration. This option provides students with individual access to technology and enables personalized learning experiences. Alternatively, we can establish a special computer room with multiple networked PCs, creating a dedicated space for students to work on language tasks and projects. This option fosters a collaborative learning environment and allows for group interactions. If budget constraints prevent these options, installing one computer in each classroom, along with a large-screen computer monitor or an overhead projector, can enable whole-class instruction with shared access to CALL resources.

After careful consideration, I recommend the establishment of a special computer room for our institute. While the ideal option of one computer per student may not be feasible due to financial limitations, a dedicated computer room provides a practical and effective solution. It offers a central hub for students to engage with CALL activities, promoting focused learning and collaborative projects. The special computer room encourages teachers to integrate technology into their lesson plans and provides a supportive environment for students to develop their digital literacy skills.

To implement the special computer room, we would need to allocate a designated space and acquire the necessary equipment, including computers, networking infrastructure, and peripherals. Exploring funding options, such as grants or partnerships with technology companies, can help alleviate the financial burden. Additionally, professional development and training for teachers on integrating CALL effectively into their instruction should be considered to maximize the benefits of this initiative.

In conclusion, the introduction of CALL through a special computer room will enhance our language teaching practices and empower students with essential digital skills. I kindly request your support and approval to proceed with this initiative, as it aligns with our institute's commitment to providing a modern and effective learning environment.

Thank you for your attention to this matter. I am confident that the implementation of CALL will have a positive impact on our institute and contribute to the overall academic growth of our students.

Here is a list of potential applications of virtual reality (VR) beyond computer games:

Controlling a robot without previous programming: VR enables users to remotely operate robots and manipulate objects in real or virtual environments without requiring extensive programming knowledge.

Virtual walkthroughs of buildings before construction: Architects and designers can use VR to create immersive virtual tours of buildings, allowing clients to explore and experience the design before construction begins.

Virtual prototyping of devices: VR simulations can simulate the functionality and user interface of devices that are still in the development phase, allowing users to interact with them virtually and provide feedback for improvements.

Simulated space exploration: VR can transport users to virtual space environments, allowing them to experience spacewalks, explore celestial bodies, and get a glimpse of what it might be like to travel in space.

Driver training and road simulations: VR-based driving simulations provide a safe and controlled environment for learners to practice driving skills, experience various road scenarios, and learn road safety without the risks associated with real-world driving.

Sign language interpretation and communication: VR can be used to develop interactive sign language recognition systems, allowing individuals who communicate through sign language to interact with virtual avatars or interfaces that can interpret and translate their signs into spoken words.

Enhanced special effects in movies: VR technology enhances visual effects in movies by creating immersive and realistic virtual environments or seamlessly integrating virtual elements into live-action footage, delivering captivating and engaging cinematic experiences.

Historical recreations and cultural experiences: VR can recreate historical events, archaeological sites, or cultural scenes, allowing users to immerse themselves in different time periods and experience historical moments virtually.

In summary, virtual reality offers a wide range of applications beyond gaming, including remote control of robots, architectural visualization, device prototyping, space exploration simulations, driver training, sign language communication, movie special effects, and historical recreations. These applications provide immersive and interactive experiences, enabling users to engage with virtual environments and activities in ways that were previously impossible.

Why are robots controlled via mounted video cameras less effective than the VR solution?

Robots controlled via mounted video cameras are less effective compared to the virtual reality (VR) solution primarily due to the time lag between seeing the image and sending corrective control signals. In the case of robots controlled by video cameras, there is a delay in transmitting the video signal from the camera to the operator's display. This delay can be influenced by factors such as the quality of the video transmission, processing speed, and network latency if applicable. As a result, the operator experiences a time lag in perceiving the real-time environment and making control decisions.

The time lag in controlling robots through video cameras poses several challenges. First, it disrupts the operator's ability to react promptly to changes in the robot's surroundings, leading to slower response times. This can be critical in situations that require precise and immediate actions. Second, the delay hinders the operator's sense of immersion and presence, as the perceived environment is not in sync with real-time feedback. This lack of synchronization can reduce the operator's situational awareness and impede effective control.

On the other hand, virtual reality systems offer a more immersive and synchronized control experience. By utilizing head-mounted displays with wide-angle lenses and sensors to track the operator's movements, VR systems provide a real-time simulation of the robot's environment. The operator can perceive the virtual world as if they were physically present, resulting in a more natural and immediate interaction with the robot. This eliminates the time lag associated with video cameras and improves the overall effectiveness of robot control.

In summary, VR solutions overcome the limitations of mounted video cameras by reducing the time lag between perception and control, enhancing responsiveness, and creating a more immersive user experience for effective robot operation.

What application of VR is expected to be the commonest to start with. 

The commonest application of virtual reality (VR) to start with is undoubtedly video games. As mentioned in the text, the biggest initial market for VR is expected to be the realm of gaming. Companies like W Industries have already made significant strides in this area, introducing VR systems like Virtuality that offer immersive experiences in video arcades. These systems typically involve a cockpit setup where players wear helmets with wide-angle lenses and liquid-crystal displays, accompanied by a set of controls that can mimic various thrilling scenarios, ranging from piloting a spaceship to racing flying motorcycles through a forest, as mentioned in the text.

VR gaming has the potential to revolutionize the gaming industry by providing players with a more immersive and interactive experience. By creating artificial worlds and allowing users to walk through, explore, and interact with virtual environments, VR technology brings games closer to real-life experiences than ever before. Players can visually and audibly engage with their surroundings, with the added dimension of being able to manipulate objects and engage in physical interactions within the virtual space.

With its ability to transport individuals to new and exciting realms, VR gaming has the potential to captivate audiences and deliver unparalleled entertainment experiences. The combination of immersive visuals, realistic audio, and interactive gameplay mechanics make VR games a compelling and enticing proposition for gamers worldwide. As a result, the gaming industry is likely to be at the forefront of the adoption and popularization of VR technology, making video games the commonest and most prominent application of VR in its early stages.

Give description of the VR visual system. How its different system works?

Virtual Reality (VR) is a computer generated 3-D (three-dimensional) world which is the simulation of the real world. Due to the features of senses (sensory features), the VR world looks like that of the real world.

Generally, the systems/VR devices are: Helmet, DataGloves, and Exoskeleton. Talking about the helmet, it has wide-angle lenses to cover the entire view and gives stereoscopic (3-D) effect. It is worn in eyes and with the help of sensors it displays color to the users. It also includes compass to record where it is pointing. These sensory features create illusion and the VR seems real. Similarly, DataGloves is worn in hand (fingers and palm) to detect exactly what the fingers are doing and transmits information to the computer. If the user tries to pick up something, the computer will make the object follow the hand to give the illusion of carrying it. Lastly, Exoskeleton is the VR device that covers the users body and allow the computer to simulate almost anything possible in real life. 

To conclude, VR uses different systems like; Helmet, DataGloves, and Exoskeleton to create illusion and make the users feel real.

Do you think the use of virtual reality in computer war games is going to affect young people's attitude to violence?

The use of virtual reality (VR) in computer war games has raised concerns about its potential impact on young people's attitudes towards violence. The immersive nature of VR can create a sense of presence and realism, leading players to emotionally engage with the virtual environment. This heightened level of immersion and identification with virtual characters may increase the likelihood of internalizing violent behaviors and attitudes.

Furthermore, the interactive nature of VR games, where players actively participate and make decisions within the virtual world, can reinforce aggressive tendencies. When individuals repeatedly engage in virtual violence and experience the immediate consequences of their actions, it can shape their cognitive and emotional responses, potentially desensitizing them to real-world violence.

However, it is important to consider that the effects of VR on attitudes towards violence are complex and influenced by various factors. Personal characteristics, upbringing, and the overall media environment all contribute to an individual's interpretation and response to violent content in VR. Continued research is needed to fully understand the impact of VR on young people's attitudes towards violence and to develop strategies for responsible game design that minimize any potential negative effects.

Does the text contradict in any way what you already know about VR systems? If so, what is the contradiction and how can it be explained?

The text presents contradictions to what is commonly understood about VR systems. It highlights several issues with hand-based input/output devices that are not mentioned in the newspaper article. Firstly, the text mentions delays in hand tracking, which can affect the user experience. In contrast, the article portrays VR as an immersive and seamless technology without mentioning any such delays.

Secondly, the text discusses the limitations of generating tactile force or feedback in VR, making fine manipulation tasks difficult and suggesting that the quality of tactile feedback is currently low. In contrast, the article suggests that users can touch and interact with virtual objects, giving the impression of a realistic experience.

Lastly, the text mentions the physical strain and lack of arm support in glove-based systems, which can lead to fatigue and limited usage. The article, on the other hand, does not address any discomfort or physical exertion associated with VR interactions.

These contradictions can be explained by the different perspectives and intentions of the sources. The article likely aimed to create a positive image of VR to captivate readers, while the text provides a more critical assessment based on practical experience and research.

It is important to consider both perspectives and be aware of the limitations and challenges in VR technology. Continued advancements may address these issues and enhance the overall VR experience in the future.

Write problem of hand input devices and its consequences.

Hand input devices in virtual reality (VR) systems encounter several problems with significant consequences. Firstly, these devices suffer from the same delays as the head-mounted display system, leading to a noticeable lag between the user's actions and the corresponding virtual response. This delay can cause users to over-compensate, affecting the interaction between their hand and virtual objects, and reducing the overall precision and realism of the experience.

Secondly, hand input devices have limited ability to generate tactile feedback. Fine manipulation tasks become challenging or even impossible due to the lack of realistic tactile sensations. This limitation hampers the user's ability to accurately grasp, manipulate, and interact with virtual objects, hindering the immersive nature of VR simulations.

Additionally, the hand-based input system requires users to keep their hands and arms unsupported. This results in increased physical exertion as users need to employ both agonist and antagonist muscle sets to perform complex tasks. Extended usage of these devices can lead to fatigue and discomfort, limiting the duration of VR sessions and potentially affecting user enjoyment.

In summary, the problems associated with hand input devices in VR include delays affecting interaction, limited tactile feedback for fine manipulation, and physical strain due to lack of support. Addressing these issues through advancements in technology and ergonomic design is crucial to enhance the user experience and improve the usability of hand input devices in VR.

How did scott french 'clone' Jacqueline Susann?

Scott French "cloned" Jacqueline Susann by utilizing an AI program he created to imitate the novelist and collaborating with it to write part of a book. The process involved Scott French writing 10% of the novel himself, while the AI program generated 25% of the content based on formulas and essential plot and characterization elements developed by French, inspired by Jacqueline Susann's work. The remaining portion of the book was a collaborative effort between French and the computer.

To achieve this, French employed the use of Nexpert Object software and received development lessons from the Bechtel AI Institute. By programming the AI system with the formulas and insights derived from Susann's writing style, French aimed to create a 350-page novel that blended his own contribution with the computer-generated content.

While some critics have labeled this approach as "computerized literary ghostwriting," French defends his actions by asserting that the way a person thinks cannot be copyrighted. He believes that the collaboration between human creativity and artificial intelligence can result in unique literary works. As of now, it is unclear if French has secured a book deal for his computer-generated novel.

What are the main differences in the way images are produced on a TV screen and on a computer screen.

The main differences in the way images are produced on a TV screen and on a computer screen are related to the writing process and the bandwidth requirements.

On a TV screen, the image is typically written in one pass. A tight beam of electrons scans the screen line by line, starting from the upper-left corner and moving to the lower right. This process is similar to reading a page of text. In contrast, on a computer screen, it takes multiple passes to write the entire image. The beam of electrons needs to scan the screen repeatedly, usually around 50-60 passes, to create the complete image. This difference in the writing process is due to the different technologies used in TV displays and computer monitors.

Another significant difference is the bandwidth. In the case of TV screens, the available bandwidth for transmitting the image is narrow. To overcome this limitation, the PAL standard (used in Europe) employs interlaced video, where each frame is split into two fields transmitted at a rate of 50 per second. This technique reduces flicker but may cause noticeable flickering of horizontal scan lines. On the other hand, computer systems typically use higher refresh rates, such as 60kHz, and non-interlaced video, which provides a more stable display.

These differences in the writing process and bandwidth requirements impact the way images are produced and displayed on TV screens and computer screens, emphasizing the distinct characteristics of each medium.

Why did the developers of the PAL system invent interlaced video? What are its advantages and disadvantages? 

The developers of the PAL system invented interlaced video because the available bandwidth for transmitting TV signals was not sufficient to transmit all 625 lines of a TV image in a fiftieth of a second. Interlaced video is a technique where each frame of the image is split into two fields, with the odd lines in one field and the even lines in the other. These fields are transmitted at a rate of 50 per second, resulting in an effective frame rate of 25 per second and reducing flicker.

The advantage of interlaced video is that it effectively eliminates noticeable flicker when viewing the TV image from a normal viewing distance, such as several yards away. By refreshing the image at a rate of 50 fields per second, the flicker is minimized, and the viewing experience is improved.

However, interlaced video does have its disadvantages. When viewed up close, such as when sitting close to a TV or computer screen, the interlaced scanning method can cause visible scan lines and flickering, which can lead to discomfort or headaches. Additionally, interlaced video reduces the vertical resolution of the image, which may result in a slightly lower image quality compared to non-interlaced formats.

Overall, the invention of interlaced video in the PAL system was a solution to the bandwidth limitations of transmitting TV signals. While it effectively reduced flicker for normal viewing distances, it may not provide an optimal viewing experience for close-up viewing.

Which of the two suggested ways of getting a signal from a computer to record on a VCR do you think is preferable?why?

The second suggestion of using a scan converter to record a computer signal on a VCR is a preferable option due to its practicality and cost-effectiveness. By utilizing the standard display signal from the computer, which is typically around 60kHz, it eliminates the need for additional hardware or modifications to the computer setup. This not only simplifies the process but also ensures compatibility without requiring a specific display adapter.*Moreover, opting for a scan converter offers versatility and flexibility. It can convert the video signal to different refresh or scan rates, accommodating various recording devices beyond just VCRs. This adaptability allows for seamless integration with different equipment, making it a convenient solution for capturing computer video.

In terms of affordability, a scan converter is a cost-effective choice compared to investing in a display adapter capable of producing PAL-standard video. This eliminates the need for additional expenses and hardware upgrades, making it a budget-friendly option for companies looking to record computer video onto a VCR.

Overall, the second suggestion of using a scan converter provides a practical, versatile, and cost-effective approach to recording computer signals on a VCR. It streamlines the process and ensures compatibility without requiring extensive modifications or significant financial investment.

Write summary of the text “24 bit colour”

The text discusses the concept of 24-bit color and its significance in displaying photographic images on computer screens. It highlights that the human eye can detect approximately 150-200 distinct shades, and to achieve a smooth gradient of shades, more colors are needed. Cheapo computer monitors, with limited capabilities, can only display solid black or white, making it necessary to have a computer that can show true shades.

The article explains that a computer creates an image using pixels, which are small squares of a single color. The more pixels used, the higher the image resolution. Each pixel is represented by a code consisting of binary digits called bits. Computers typically work with groups of eight bits, known as a byte, allowing for 256 shades of gray from black to white. A greyscale display can show all these shades.*To achieve full-color photographic effects, the human eye's ability to detect shades in red, green, and blue is considered. Using eight bits per color, only 256 colors can be displayed, resulting in a mildly posterized effect. However, to generate 256 shades for each color and achieve natural-looking tones, 24 bits are required, leading to a possible 16.7 million color shades.*While 24-bit color is necessary for activities like color photographic retouching, an 8-bit color monitor is adequate for linework and picture placement. Special circuit boards and ample memory are required for 24-bit color, making it costlier than 8-bit options. Ultimately, the choice depends on specific requirements, with 24-bit color providing superior color accuracy and fidelity, albeit at a higher cost.

Describe how ring network configuration works with a diagram.

A ring network configuration is formed by connecting devices in a continuous loop, resembling a ring shape. The network allows data to flow in only one direction around the loop, and it moves at a constant speed. Devices are attached to the network and may send information only when they are in control of the "token."

The token is a special package of data that indicates which device has control over the network at a given time. Only the device possessing the token is allowed to send data. This mechanism ensures orderly communication within the network and prevents data collisions.

In addition to regular devices, such as computers or terminals, a ring network configuration can include a file server. The file server functions as a central repository for storing and managing files that can be accessed by other devices in the network.

When a device has the token, it can transmit data, including files, by attaching the file to the token. The token and attached file circulate around the loop until they reach the destination device, which can be the file server or another device. The receiving device picks up the token, extracts the attached file, and processes it accordingly.

Only one device can possess the token and send data at any given moment, ensuring that there are no data collisions within the network. Each device must wait for its turn to possess the token and transmit data, maintaining an orderly flow of information.

By including a file server in the ring network, centralized file storage and access are facilitated. The file server serves as a dedicated location for storing and managing files that can be retrieved and shared by other devices within the network. This enhances the network's functionality and enables efficient file sharing among the connected devices.

Show your acquaintance with a clipboard technology pointing out how this technology works.

Clipboard technology, as described in the article, is a revolutionary approach to inputting data into computers without the need for a traditional keyboard. It replaces the keyboard with a liquid crystal display (LCD) screen and an electronic stylus, allowing users to input data by directly printing individual letters on the screen. Here's a breakdown of how the technology works:

Hardware: The clipboard PC utilizes a combination of hardware and software to function. The hardware component involves the LCD screen, which is covered by a sheet of glass with a transparent conductive coating. The glass conducts voltage, and when voltage is sent across it in horizontal and vertical lines, it forms a fine grid.

Stylus Interaction: The stylus, which acts as an electronic pen, interacts with the screen. It essentially functions as a voltmeter, detecting the voltage at a specific point on the grid when it touches the screen. By monitoring the stylus position several hundred times per second, the computer can determine the coordinates of the stylus and activate corresponding liquid crystal pixels on the screen.

Input Recognition: To make the written input comprehensible to the computer, powerful software is employed. The software analyzes the stylus movements and looks for moments when the tip doesn't touch the screen for a third of a second or more. Each time this happens, the software assumes that a letter or number has been written.

Pattern Recognition: The pixel positions of the freshly written character are then passed on to the computer's pattern recognition software. This software cleans up the character by smoothing out lines and removing unwanted dots. The remaining lines and curves are compared to a database of templates stored in the computer's memory. These templates represent various versions of letters and numerals.

Character Encoding: Once the closest match is found, the software encodes the recognized character in memory and displays it on the screen as if it had been typed. This entire process, from stylus input to character recognition and display, occurs within a fraction of a second.

Additional Features: Clipboard computers offer additional features such as deleting a word by drawing a line through it and navigating to the next page by flicking the stylus at the bottom of the screen, simulating the action of turning a book's page.

Clipboard technology represents a significant advancement in user-friendly computing by enabling users to input data through handwritten gestures on a screen, eliminating the need for typing and complex commands. With advancements in software, it has the potential to understand various writing styles and languages, making it a promising technology for the future.
