Abstract

The inductive tongue-computer interface allows individuals with tetraplegia to control assistive devices. However, controlling assistive robotic arms often requires more than 14 different commands, which cannot always fit into a single control layout. Previous studies have separated the commands into modes, but few have investigated strategies to switch between them. In this feasibility study, we compare the efficiency of switching modes using buttons, swipe gestures and double taps using a preliminary version of a new non-invasive mouthpiece unit (nMPU), which includes an integrated activation unit and a single sensor board. Three participants controlled a JACO assistive robot to pick up a bottle using different mode-switching strategies. Compared with switching modes with buttons, switching modes with swipes and double taps increased the task completion time by 21% and 58% respectively. Therefore, we recommend that configurations with multiple modes for the non-invasive tongue-computer interface include buttons for mode-switching.Clinical relevance-Cumbersome mode-switching strategies can lower a control interface's responsiveness and contribute to end-user abandonment of assistive technologies. This study showed that using buttons to switch modes is more reliable. Moreover, this study will inform the development of future control layouts with improved usability.
