31.Introduction

The wheelchair users in Thailand have been mostly perceived as burden of society due to the mobility impairment and the limited scope of occupation.

The public transportation service at present is still inappropriate for a wheelchair user without caregiver.

1.Usability: (physical and mental aspects)

+ driving without moving from wheelchair+ perform the driving operation with the simple mechanical driving system.+ satisfied with the affordable expenses

for obtaining and maintenance.

Usability 3. Design consideration


33

2.Accessibility: (integral part of the physical usability aspects)+ wheelchair users can transfer themselves easily from ground on board + perform any operation face toward+ the mechanical systems are able to

function with or without electrical power

Accessibility 3. Design consideration


34Accessibility 3. Design consideration

Space requirement for smooth u-turn in a wheelchair


35Accessibility 3. Design consideration


36

3.Appearance: (aesthetically acceptable for Thai people)

+ similar with the existing 3-wheeled taxi + bare shell designed for modification by the user’s requirement+ encouraging sportive but not speedy look

Appearance 3. Design consideration

95DiscussionThe vehicle named after the 360 degree disk floor system: DISK+ABLE

To encourage disabled people to drive and or work on board with assistive equipments


96ConclusionFurther research and development:+ Safety system for passenger restraint

system + The adjustable steering handle+ The adjustable back-side mirror allocation for better vision+ The multi-occupational purpose at the storage space

The completion of DISK+ABLE as assistive vehicle is to enable the user to live a normal and equal life as others in Thai society
