IntelliKeys is an alternative keyboard designed to meet the needs of students with physical disabilities. It is a customizable, flat, touch-sensitive device. Unlike standard keyboards with a fixed set of keys, the configuration of IntelliKeys can be easily changed by sliding different overlays onto the touch sensitive area. IntelliKeys USB plugs into the computer's USB port and provides access for anyone with physical, visual, or cognitive disabilities who has difficulty using a standard keyboard. In combination with its many overlays, it provides individualized support for young students, struggling learners, and ELL students. The universal design of the overlays provides large, well-spaced keys in high contrast colors to help students locate letters, numbers, words, and directional arrows. Concepts are broken down into manageable components, with streamlined choices, fewer concepts at a time, pictures to support learning—even student photographs for personalization. POWER: USB Port. DIMENSIONS: 17.25 inches length x 10.25 inches height x 1.125 inches depth. COMPATIBILITY: Macintosh and Windows compatible. COLOR: Variety. WARRANTY/GUARANTEE: As stated by the manufacturer.
