Area of Science:

Assistive Technology
Robotics
Human-Computer Interaction

Background:

Individuals relying on single switch scanning face challenges in controlling powered wheelchairs.
Existing single switch scanning methods can be inefficient and demanding for users.

Purpose of the Study:

To develop and evaluate an intelligent single switch wheelchair navigation (ISSWN) system.
To improve safety, comfort, and efficiency for powered wheelchair users employing single switch scanning.

Main Methods:

Developed ISSWN system integrating a powered wheelchair, laser rangefinder, single switch interface, and computer.
Implemented context-sensitive and task-specific scanning options based on sensor data and user input.
Conducted trials with 9 able-bodied participants performing a navigation task.

Main Results:

ISSWN significantly reduced switch presses to 43.5% compared to traditional methods (p < 0.001).
Participants demonstrated a significant 39.1% improvement in completion time after only two trials (p < 0.001).
Enhanced driving safety and efficiency were observed in the navigation task.

Conclusions:

The ISSWN system offers a significant advancement in powered wheelchair control for single switch users.
The system effectively reduces user effort and improves navigation performance.
ISSWN holds promise for enhancing independence and quality of life for individuals with mobility impairments.
