Abstract

Intelligent powered wheelchairs can increase mobility and independence for older adults with cognitive impairment by providing collision avoidance and navigation support. The level and/or type of control desired by this target population during intelligent wheelchair use have not been previously explored. In this paper, we present user attitudes, needs, and preferences in a study conducted with a mock intelligent wheelchair offering three different modes of user control. Users wanted to be in the loop during wheelchair operation and/or high-level decision making, and also provided specific contexts where an autonomous wheelchair would be helpful. Participants identified benefits of and concerns with intelligent wheelchairs, along with desired features and functionality. The paper presents the implication of these findings and provides specific recommendations for future intelligent wheelchair development and deployment.

Participants tested a different scenario each day, and the study was not counterbalanced such that an equal number of participants tested each scenario on a day.

Despite some statistically significant results, note that the lowest median QUEST 2.0 rating for each mode in all scenarios and survey items was 4.0 (“quite satisfied”). Only two ratings below 3.0 (“more or less satisfied”) were seen over all trials, suggesting that participants either felt uncomfortable to admit when they were unsatisfied, or were in fact generally quite satisfied with all modes.
