  • Synaptics Announces Industry-First USB Dual Pointing Solution Custom Design Is Now Offered in IBM USB Desktop Keyboards
    Synaptics Announces Industry-First USB Dual Pointing Solution Custom Design Is Now Offered in IBM USB Desktop Keyboards SAN JOSE, Calif., Mar 18, 2003 /PRNewswire-FirstCall via COMTEX/ -- Synaptics® Incorporated (Nasdaq: SYNA), a leader in human interface solutions for mobile computing and communications devices, today announced that IBM will use Synaptics' USB dual pointing solution in its UltraNav(TM) system for a new USB desktop keyboard. This marks the industry's first USB dual pointing device, and the first IBM USB keyboard to contain both a TrackPoint(TM) pointing device and TouchPad(TM). "The same attention to improved ergonomics and increased usability found on IBM's ThinkPad T30 is now available on a desktop keyboard," said Don Kirby, General Manager of the PC Group at Synaptics. "Synaptics' relationship with IBM allows for continued innovation in custom interface development and leadership in next generation mobile and desktop computing navigation devices." To complement the UltraNav system, IBM has created a customized software wizard, in a question-and-answer format, making it simple for users to configure individual preferences on the dual pointing solution. "Dual pointing device solutions deliver a significant increase in desktop flexibility and usability," explains Randy Giusto, Vice President, Personal Technologies and Services, of market research firm IDC. "By offering interface options on a USB keyboard and easy-to-use configurable software, you can provide technology leadership to meet the specific needs of the end user." About Synaptics Incorporated Synaptics develops advanced interface solutions for products as diverse as notebook and desktop computers, mobile computing and communications devices, automotive applications and security solutions.

  • System Input Devices
    System Input Devices Since the computer is a digital device, all input devices must provide data in digital form. A key function of most of the devices listed below is to convert data from analog to digital form for transmission to the computer through a hardware interface (for our purposes, a port). Keyboard The keyboard is the most popular input device for a computer. It translates numbers, letters, symbols and control keys into digital data (bytes) that can be interpreted by the PC. Most English keyboards today are based on the QWERTY design, a de facto standard. It takes its name from the first six letters seen in the Standard IBM Keyboard keyboard's top first row of letters. An alternative to the QWERTY keyboard is the Dvorak keyboard, invented to achieve a more efficient method of typing, by placing keys used more often in the "home key" positions. Sadly, the Dvorak keyboard never received widespread use. Some specialist keyboards have extra function keys that perform Korean keyboard special actions when pressed. An example is a gaming keyboard. Some have fewer keys, like a chord keyboard. Keyboards may come in wireless, foldable or virtual varieties. Logitech G15 Gaming-Keyboard A Microwriter MW4 hand- held chord-keyboard > Ergonomic keyboard Mouse/Pointing Device A mouse is an input device that allows the user to point (locate) and click (select) . With the rise in graphical user interfaces, mice became the most commonly used method in controlling a computer. A mouse is used to manipulate objects and text on the computer screen. This device can be plugged in or can be cordless.
