| This paper evaluates the performance of individuals with cerebral palsy (CP) using an inertial human-computer interface (HCI) based on head movements and a novel facilitation algorithm which we named MouseField. Seventeen participants from 3 centers specialized in CP participated in a series of tests that evaluated rapidity and accuracy in pointing tasks using a head mouse named ENLAZA, with and without MouseField. Cluster analysis was used to classify the participants into three categories, C1-C3 ordered by throughput. MouseField improved rapidity in C2 and C3 and accuracy in C3. Although the accuracy of the least impaired (C1, MACS IV-V) decreased, MouseField improved task performance of users with severe motor disorders (MACS V), with decrements of 33.3% and 65.5% in the task execution time. The results show that severely impaired individuals who cannot use traditional input devices could benefit from using MouseField and ENLAZA for a facilitated navigation that minimizes targeting errors. | |
