Power wheelchair joysticks have been used to control a mouse cursor on desktop computers, but they offer no integrated text entry solution, confining users to point-and-click or point-anddwell with on-screen keyboards. But on-screen keyboards reduce useful screen real-estate, exacerbate the need

that cerebral operations fit hierarchical series like those the association model presupposes. Undoubtedly, parallel processing mechanisms are superimposed within the brain on a basic hierarchical design. Sensory input is processed through different levels leading to neural and behavioral events of quite

The natural interaction aspects of the user interface are more significant in the devices of impaired users than the devices of healthy users. This work investigates three controls as the wheelchair controllers according to the design and physicality principles; conventional joystick, isometric

differences in pressure relieving abilities among six commonly prescribed wheelchair cushions and whether differences were related to the participant's body mass. In addition, the participant's perception of cushion comfort was investigated. A convenience sample of 40 adult wheelchair users were

to stationary receivers. The sensors are low power (milliwatts), high resolution (millimeter) low cost (a few dollars per channel), have low latency (millisecond), high update rate (1 kHz), high immunity to noise (>72 dB), are not affected by clothing, surface texture or reflectivity, and can operate

Low-level programming of a 9-degree-of-freedom wheelchair-mounted robotic arm with the application of different user interfaces

The objective of this research is to develop a semi-autonomous architecture for an intelligent wheelchair, “a wheelchair-navigation agent, ” that comprises perceptual and navigational capabilities by means of computer science, robotics, and sensor technology. The perceptual navigation system
