LOMAK
LOMAK is an acronym for Light Operated Mouse And Keyboard. It is an assistive technology device designed for use by people who cannot use a standard computer keyboard and mouse. The Lomak is clipped to an adjustable stand placed vertically underneath the computer screen and is operated by a small laser pointer mounted on a hat or headband. Some people who have arm movement can alternatively use the Lomak horizontally with a hand-pointer. It can be used as an additional keyboard and mouse with any desktop or laptop computer which has a spare USB port. Like many computer peripherals for people with special access needs, it is very expensive, about $1500.
== Description ==
The Lomak keyboard is a USB 1.0 device which plugs into a computer's USB port. It does not require installation of any software. When used in mouse mode, it can move the computer's mouse cursor at fast or slow speeds as selected by the user, and generate left or right clicks on command. When used in keyboard mode, it can generate any of the characters created by a standard keyboard, including Shift, Ctrl, and Alt combinations.
The keyboard has three circles of ''keys'' each surrounding a central ''Confirm'' sensor, with setup and control keys in a horizontal bar below. Each key comprises a light sensor and an associated LED indicator which turns on when the key is active. Each change of key is optionally accompanied by an audible click. Characters are selected and sent to the computer when confirmed.
The head-pointer contains a laser and operates from an internal battery for about eight hours between charges. It turns off when pointed away from the keyboard and left stationary for a time. It has an internal switch which awakes the device when it is moved.
