This paper proposes a novel driving-assistance system for manual wheelchairs with consideration of both uphill and downhill conditions. On an inclined road, there is a high risk of a wheelchair moving in a direction that the user does not intend. In our previous works, the user has driven our assistive wheelchair in the usual manner. Our proposed system estimates its user's intentions and passively...
In the recognition of an object situated in front of us, we firstly watch it and then try to touch it to feel the tactile and haptic sensation to be perceived by our hands. Various virtual reality and augmented reality systems have been introduced with the growing computational powers, however visual and auditory information related with a virtual object is mainly presented simultaneously to a user...
This paper proposes a novel driving assistance system for a manual wheelchair. On an inclined road, there is a high risk of a wheelchair moving in a direction that the user does not intend. Using only servo brakes on each wheel, our proposed system negates the wheel traction that is generated by the road's inclination. Our system measures the road's inclination and estimates the wheel traction generated...
