Software Developed by KPR

All of our software is designed to support optimal accessibility for computer users with physical impairments. All of them are free to try, and almost all are free to use permanently (with Compass software being the only exception). KPR thanks ej-technologies for granting a free license to their install4j multi-platform installer builder.

Aim Online beta

This is an browser-based version of the Aim test within our Compass software. It helps assess ability to use a mouse or other pointing device to select targets on the screen. Collects speed and accuracy data and creates some cool reports. Still in beta -- it works but data storage is a bit fragile. Free!

AT-node for Access

Search the available research on the use of computer accessibility interfaces by people with physical disabilities. Includes text entry rate data from studies published since 1986. Search by diagnosis (such as cerebral palsy, spinal cord injury, muscular dystrophy), interface (like assistive keyboard, on-screen keyboard, speech recognition), and more. Multi-platform web application. Free!

Keyboard Wizard

Let Keyboard Wizard help make your typing faster and easier.

Our extensive user research shows that sometimes a little change can make a big difference. Available for Windows. Free!


The point of AutoIDA is to fully automate the process of identifying and activating optimum Windows settings for a particular user. It's an extension of our work on Keyboard Wizard and Pointing Wizard software. This is a proof-of-concept prototype for both keyboard and mouse settings. Available for Windows. Free! but please note that it is not a finished product, and has only been tested within our own research projects.

ModKeys Software

ModKeys is a free Windows program that completely disables the automatic key repeat behavior, except for the cursor keys. This can allow people who tend to hold keys down a little too long to type easier and with fewer errors. With ModKeys, the regular alphanumeric characters will never repeat, no matter how long you hold them down. But you can still use auto-repeat with the cursor keys, which is the main purpose for auto-repeat. You can adjust the key repeat settings within Windows to make control of cursor movements easier; this can be done in the Windows Control Panel, or with the assistance of our Keyboard Wizard program.

This is a simple macro program produced using AutoHotkey. It is best suited for individuals who are not super-fast typists, as it does not always respond quickly enough to the keystrokes of fast touch-typists. Compatible with Windows. Free!
