We have developed an intelligent single switch scanning interface and wheelchair
navigation assistance system, called intelligent single switch wheelchair
navigation (ISSWN), to improve driving safety, comfort and efficiency for
individuals who rely on single switch scanning as a control method. ISSWN
combines a standard powered wheelchair with a laser rangefinder, a single switch
scanning interface and a computer. It provides the user with context sensitive
and task specific scanning options that reduce driving effort based on an
interpretation of sensor data together with user input.
Trials performed by 9
able-bodied participants showed that the system significantly improved driving
safety and efficiency in a navigation task by significantly reducing the number
of switch presses to 43.5% of traditional single switch wheelchair navigation (p
< 0.001). All participants made a significant improvement (39.1%; p < 0.001) in
completion time after only two trials.
