Understanding how to improve the accessibility of computers through cursor control studies

ABSTRACT

People with motion-impairments often find it difficult to perform many of the actions required to interact with a computer. This paper presents the results of an on-going series of experiments designed to understand how using force feedback affects interaction for motion-impaired users. Point and click tasks were analyzed using new cursor control measures. The results showed significant improvement in throughput for all users with force-feedback and the cursor control measures were effective in capturing the differences between the conditions.
