Initial results from using Preference Ranking Organization METHods for Enrichment of Evaluations to help steer a powered wheelchair

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Research is presented that uses PROMETHEE II to determine a direction for a powered wheelchair. This is the only time that PROMETHEE II has been employed for this sort of use. A wheelchair driver proposes a preferred speed and direction, and PROMETHEE II recommends a reliable and trustworthy bearing. The two directions are combined so that the wheelchair safely avoids obstacles. Ultrasonic sensors and joysticks provide the inputs and the final direction is a combination of the preferred bearing and a route that safely avoids obstacles. The systematic decision-making process assists the user with steering safely. Sensitivity analysis explores the potential directions and an appropriate direction is chosen. A driver can reject or cancel a decision suggestions by holding their joystick in a fixed place.
