CalcuScan, model M126, is a scanning calculator program designed for use by students with physical or neurological disabilities, cerebral palsy, or low vision. This calculator program can be used as a classroom math aid for teachers and students. Multiple key layout options and access modes are provided to suit specific teacher and student needs. The user can edit and reassign key names and functions; display calculator key layouts at any size, up to full-screen, with high-contract keys and digits; enter answers to problems with or without using the calculator functions; specify and save layout, access, sound, miscellaneous, and work options (for example, scan interval, say value, auditory scan, scroll/normal register); and display or print records of student progress. Scanning modes include auto, inverse, and one- or two-switch scans, and dwell access for head-pointing devices. In the Problem Editor, teachers can view, create, and edit math problems and save lists of problems. Numeric problems and word problems are entered just as they will be displayed to the student. The program can display math problems to be solved by the student using the calculator or by entering the answer directly. OPTIONS: Keystrokes Onscreen Keyboard, model F1OI102.
