I surveyed several Web sites to find a solution for a student with one hand. Traditional keyboards can be configured to have sticky keys for those people who do not have use of two hands, but I though there must be something better—I thought there must be a company somewhere that has a product for single-handed use. Sure enough, after a good deal of Web surfing, I was able to find a very useful product. I discovered several products, but after a good deal of evaluation, the BAT Personal Keyboard seemed to be the best for my purposes. The BAT is a one-handed compact input device that replicates all the functions of a full-size keyboard, but with greater efficiency and convenience. After talking with a number of colleagues who have used the BAT and my one-handed student, I decided to buy one. I remember the day it arrived. I took it out of the box and I tried it. I must confess that I did not have good feelings about this techno-gizmo. Even though I had seen pictures of the BAT and had seen children using them, it was quite a different matter to be "at the controls" and be expected to make this thing work properly. There was a large card that accompanied the BAT—this large card (it seemed to be huge to me) contained all the keystroke combinations—it seemed more daunting to learn than Morse code. I was not at all sure how my student would react to memorizing all that. The next day the student came to class and I gave him the new keyboard and let him go off in a corner and read the directions while I gave the class their assignment and set them to work. When I returned I was not sure what I'd find—would the boy be sadly disappointed by a daunting task, or would he be politely thankful and want to get to work with the other students in his class. I must confess that I was very pleasantly surprised. He had memorized A through L on the BAT. "The BAT is easy to learn and use," he said. Letters, numbers, commands, and macros are simple key combinations. If you have the right motivation it's easy. Apparently my motivation was quite low—I didn't need an alternative to the traditional keyboard—my student did. The BAT is a fully functioning keyboard for use with one hand. It has an innovative and compact design that is ideal for individuals with physical (or visual) impairments. The keyboard's small size allows users to easily port the BAT from home to work or school, as well as to place the keyboard in the most comfortable position to meet their needs. InfoGrip Inc. has another product to enhance speed and efficiency of the BAT. ChordEasy software, a word expansion and macro program, is included with the BAT so that the keyboard can be customized. The BAT employs an input system called "chording." Similar to Braille, combinations of keys are pressed simultaneously. The BAT has seven keys, four for the fingers and three for the thumb. The center thumb key is used in combination with the four finger keys to type "space" and "A" through "Z." The two outer thumb keys are used for special keys like "Alt," "Shift," and cursor movement. "Sticky" or "latching" keys are used to enter multiple key sequences, i.e., Alt F to open a file. The BAT is a keyboard; it is not a mouse. However, all cursor movements can be achieved, and with Windows 95 and System 7 for Macintosh, users can turn the keypad into a mouse. If a pointing device is desired, most users mount a portable Glidepoint touchpad (available from InfoGrip) just above the thumb keys, or place a trackball or mouse on the low side of the BAT, thereby minimizing hand movement. Users can do anything on the BAT keyboard that they would with a traditional keyboard and more. Included with the BAT is ChordEasy software. ChordEasy enhances user productivity, providing a customized short hand or Quickkeys type feature. Abbreviation expansions and macros turn long words, phrases, or key sequences of up to 250 characters into two strokes. ChordEasy also allows the users to lock the BAT in Macro Mode, requiring only one stroke to be entered, transforming it into a fully customizable keyboard. The InfoGrip Inc. indicates that those who use their product have a wide range of physical disabilities, including the following conditions:
My student is very happy
with the BAT—I am, too. He's at the regional high school now—he's in 7th
grade, and I understand that he carries the BAT around with him from class
to class.
