Touch screen with feelings-T-PaD
This document discusses the development of a tactile pattern display (TPaD) technology that adds haptic feedback to touch screens. TPaDs use ultrasonic vibrations to vary the friction between a user's finger and the touch surface, creating the illusion of different textures. This allows touch screens to provide tactile feedback without changing the visual display. TPaDs have applications in assistive technology, virtual reality, advertising, and more. However, reducing their high power consumption is needed for widespread use on mobile devices.
Jumper wires
A jumper wire is a short conducting wire used to connect two points in a circuit. It has connectors or pins at each end to allow connections without soldering.

Unit 2 input-output
An input device sends data to a computer. Common input devices include keyboards, mice, touchscreens, cameras, and microphones. Keyboards typically have printed letters and symbols and pressing keys corresponds to written symbols. Keyboards come in different sizes for different devices like standard, laptop, and thumb-sized keyboards. Pointing devices like mice, touchpads, and trackballs allow users to control the cursor position on a screen. Computer vision devices like webcams and scanners can also serve as input devices by capturing images and documents.
Input and output devices.pdf
peripheral device, also known as peripheral, computer peripheral, input-output device, or input/output device, any of various devices (including sensors) used to enter information and instructions into a computer for storage or processing and to deliver the processed data to a human operator or, in some cases, a machine controlled by the computer. Such devices make up the peripheral equipment of modern digital computer systems.
Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices (which partake of the characteristics of the first two). An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer. An output device reverses the process, translating the digitized signals into a form intelligible to the user. At one time punched-card and paper-tape readers were extensively used for inputting, but these have now been supplanted by more efficient devices.
E-ball PPT BY Mukesh
The document describes E-Ball, a spherical computer measuring 160mm in diameter that contains all the components of a traditional computer. E-Ball uses an LCD projector to project a virtual keyboard and display onto any flat surface. It has features like a wireless mouse, large storage, RAM and processors. To use it, the user presses the power button to open E-Ball and projects the keyboard and screen. E-Ball allows computing in small spaces and on the go. While portable and powerful, it also has high costs and potential hardware issues.

E ball pc technology & space mouse
The e-ball is a sphere shaped computer concept which is the smallest design among all the laptops and desktops have ever made.
This ball predicts the future of computing.
You might have seen many things like this but the unique feature of this ball is that when it is closed, no one can guess that whole computer is hidden inside this ball.
Input Devices
Input devices allow users to enter data and instructions into a computer. Common input devices include keyboards, mice, scanners, joysticks, microphones, and digital cameras. These devices convert user input into a format that computers can process. Keyboards are the primary input device for entering text. Mice are commonly used to control screen cursors and select items. Scanners are used to digitize images and documents.
A keyboard
The keyboard, monitor, mouse, and light pen are four common interaction devices that have evolved over time. The keyboard started as a typewriter-style input and remains widely used today on computers and mobile devices. Monitors transitioned from monochrome CRT displays to color LCD screens. The mouse was included with more computers in the 1980s and now features scroll wheels and multiple buttons. The light pen was used for drawing on CRT displays but is obsolete with LCD screens. Emerging technologies like touch screens, digital pens, and paper-like displays may impact these traditional devices going forward.

I Hourly Test IT
This document contains two practice tests for an Introduction to IT course. Test A contains three questions - the first asks to draw and explain the block diagram of a computer (10 marks), the second asks to list 5 DOS commands with syntax and examples (5 marks), and the third asks two decimal to binary conversions (5 marks total). Test B follows the same format but contains different questions - describing computer generations (10 marks), listing 5 input devices (5 marks), and performing one decimal to octal and one hexadecimal to binary conversion (5 marks total). Both tests are worth a maximum of 20 marks and are to be completed in 1 hour.
Software Metrics
The document discusses different types of software metrics that can be used to measure various aspects of software development. Process metrics measure attributes of the development process, while product metrics measure attributes of the software product. Project metrics are used to monitor and control software projects. Metrics need to be normalized to allow for comparison between different projects or teams. This can be done using size-oriented metrics that relate measures to the size of the software, or function-oriented metrics that relate measures to the functionality delivered.
