  • Tech Talk Technology Considerations to Improve Access, Involvement, Outcomes
    Tech Talk Technology Considerations to Improve Access, Involvement, Outcomes Phonak Roger Touchscreen Personal DM System Your student uses an Phonak Roger Touchscreen personal DM (digitally modulated) system to access auditory information in the classroom. The term DM system refers to what was previously known as a personal FM system. While FM/DM systems may have a different physical appearance, they all function in a very similar manner. The teacher wears a microphone and transmitter that sends their voice to receivers that ‘talk to’ the hearing aids/cochlear implants. Consistent and proper use of this technology is imperative. Phonak Personal DM Receivers The part of the DM system, worn by the student, that ‘receives’ the teacher’s voice from the DM microphone and sends it to the hearing aids/cochlear implants. These style of receivers can be integrated with the students’ hearing aids or connect to the hearing aids via an audio shoe. This style of receiver ‘talks’ to the hearing aids/cochlear implants via an electromagnetic signal. The student wears this neck loop device around their neck, either inside or on top of clothing. Phonak Touchscreen Transmitter & Microphone The part of the Touchscreen that the teacher wears to ‘transmit’ their voice to the student’s DM receiver(s). The three, small dots on the face of the Touchscreen are the microphone openings. Any time something touches or rubs against these openings, unwanted sound will be transmitted to your student’s brain. The placement of the Touchscreen will strongly impact how well your student accesses verbal instructions. The Touchscreen must be worn unobstructed at the STERNUM LEVEL (no lower).

    COMPUTING BASICS http://www.flickr.com/photos/oskay/472097903/ CSCI 135 - Fundamentals of Computer Science I 2 Outline • Computer Basics • Programs and Languages Hardware and Memory • Most modern computers have similar components including • Input devices (keyboard, mouse, touchscreen, etc.) • Output devices (display screen, printer, etc.) • A processor • Two kinds of memory (main memory and auxiliary memory). Main memory • Working memory used to store • The current program • The data the program is using • The results of intermediate calculations • Usually measured in megabytes or gigabytes (e.g. 8GB RAM) • RAM is short for random access memory • A byte is a quantity of memory Bits, Bytes, and Addresses • A bit is a digit with a value of either 0 or 1. • A byte consists of 8 bits. • Each byte in main memory resides at a numbered location called its address. Main Memory • Data of all kinds (numbers, letters, strings of characters, audio, video, even programs) are encoded and stored using 1s and 0s. • When more than a single byte is needed, several adjacent bytes are used. • The address of the first byte is the address of the unit of bytes. • When the computer is turned off, main memory is erased (volatile memory). Auxiliary Memory • Auxiliary memory uses devices such as a hard drive, USB drive, etc. • Data (files) need to be “saved” to the auxiliary memory • Data is still stored in bits and bytes • When the computer is turned off, this data does not go away (persistent storage) Programs • A program is a set of instructions for a computer to follow. • We use programs almost daily (email, word processors, video games, bank ATMs, etc.).

  • Interactiles: 3D Printed Tactile Interfaces to Enhance Mobile Touchscreen Accessibility
    Interactiles: 3D Printed Tactile Interfaces to Enhance Mobile Touchscreen Accessibility Xiaoyi Zhang1*, Tracy Tran1*, Yuqian Sun1, Ian Culhane2, Shobhit Jain1, James Fogarty1, Jennifer Mankoff1 Computer Science & Engineering1, Mechanical Engineering2 DUB Group | University of Washington {xiaoyiz, tracyt28, ys47, shobizz, jfogarty, jmankoff}@cs.uw.edu, [email protected] ABSTRACT The absence of tactile cues such as keys and buttons makes touchscreens difficult to navigate for people with visual impairments. Increasing tactile feedback and tangible interaction on touchscreens can improve their accessibility. However, prior solutions have either required hardware customization or provided limited functionality with static overlays. Prior investigation of tactile solutions for large touchscreens also may not address the challenges on mobile devices. We therefore present Interactiles, a low-cost, portable, and unpowered system that enhances tactile interaction on Android touchscreen phones. Interactiles consists of 3D-printed hardware interfaces and software Figure 1. Interactiles allows people with visual that maps interaction with that hardware to manipulation of impairments to interact with mobile touchscreen phones a mobile app. The system is compatible with the built-in using physical attachments, including a number pad (left) screen reader without requiring modification of existing and a multi-purpose physical scrollbar (right). mobile apps.

  • Things to Know When Operating a Panel Computer in Oil and Gas Environment
    THINGS TO KNOW WHEN OPERATING A PANEL COMPUTER IN OIL AND GAS ENVIRONMENT The purpose of this document is to inform the users of our Panel Computer on precautions to be taken when the product is used in oil and gas environment. The information contained herein is based on analyses of data over a period of years and should not be considered exhaustive in nature as Panel Computers can experience other failures not documented here. On the other hand, this document is not a substitute for scheduled maintenance, which should always be a common practice for any equipment used in an industrial environment. The following components should be given due consideration: 1. Hard disk drives 2. Power supply 3. Touch/keypad screen overlay Hard Disk Drive Of all the components used in Panel Computer, the hard disk drives are the most sensitive to shocks and vibrations. In fact, hard disk manufacturers indicate an outgoing defect rate of 1% for most hard disk drives. They recognize that these drives are subjected to a certain amount of shock and vibration during transportation. What this means is that for every one hundred hard disk drives received by a manufacturer of Panel Computer products, one hard disk is expected to fail prematurely. Data shows that more than half of all malfunctions of Panel Computers are the result of these two problems: shock and vibration. The impact of shocks and vibrations is most severe when the hard disk drive is operating, which can result in the read/write head damaging the disk surface. Since the read/write head operates only a few micrometers above the disk surface, even a slight shock can cause the head to contact the disk surface and damage its outermost magnetic layer.

    s Class -IV Super Computer Year- 2020-21 1 1. Input and Output devices • Focus of the Chapter 1. Input devices 2. Output devices • Introduction The computer will be of no use unless it is able to communicate with the outside world. Input/output devices are required for users to communicate with the computer. An input device sends information to a computer system for processing. An input device tor a computer allows you to enter information. An output device can receive data from another device, but it cannot send data to another device. There are different devices of the computer that help it to do work. Input Devices The devices which are used to input the data and the program in the computer are known as "Input Devices". For the text input, keyboard are used, microphone is used for audio or sound input. 2 Keyboard The keyboard is the most common input device. A 'keyboard' is a human interface device which is "-presented as a layout of buttons. It is a text-based input device that allows the user to interact with the computer through a set of keys mounted on a board. Mouse After the keyboard, the mouse is the most common type of input device. A mouse makes the process of navigating the screen much easier than trying to use just a keyboard. A mouse usually uses a ball, light or a laser to track movement. Joystick A joystick is an input device consisting of a large pointed stick and input buttons on it. We can use this for playing games on the computer.
