Development of an electrical wheelchair using an accelerometer sensor

Abstract

While the needs of many individuals with disabilities can be satisfied with power wheelchairs, some members of the disabled community find it difficult or impossible to operate a standard power wheelchair or the smart wheelchair due to the required skills to drive the wheelchair along the desired path. In this project, an electric wheelchair was developed, which the patient can control easily by using an accelerometer sensor embedded in the patient’s head. The accelerometer sensor allows the selection among 4 sensitivities including a sleep mode to make it ideal for handheld battery powered electronics. It [not sure what this “It” refers to] was used popularly [change “used popularly” to “commonly used”?]in science and hi- tech areas by the simple use [I don’t know what to make of “by the simple use”] and many measuring functions. [“in” or “for” many measuring functions?] Moreover, a DAQ assistant and Labview program were used to collect and process sensor signals to control the wheelchair using the mathematic functions. These functions were calculated based on the differences of tilt angle [with “differences” we usually use “between” or “in” followed by at least 2 plural nouns; or do you mean “difference in tilt angles”? The grammar in the latter case is correct, but because I don’t know what “tilt angle” is, I don’t know if it makes sense] of the accelerometer sensor.
