Wheelchair Rooftopper System Wheelchair users in Hong Kong often require other people’s assistance when driving or taking private vehicles, and that it also takes much space for storage of wheelchair. To address this pain point, APAS of HKPC provides technical support by developing a Rooftop Wheelchair Storage System for wheelchair users who want to be drivers and put the wheelchair onto the rooftop space without occupying the passenger compartment. The system comes along with a mobile app which can assist the drivers to operate the loading and retrieving of the wheelchair by using smartphone within 30 seconds. Most importantly, it is not a disruptive modification such that the users can detach the system and reinstate the vehicle condition without affecting the vehicle's resale value. Advantages include: • Easy to install • Not a permanent modification • Adaptive to different vehicle models
