Many persons suffer from severe disabilities such as amyotrophic lateral sclerosis (ALS) caused by neurological disorders. Such kinds of disabilities bring various restrictions to communication and circumstance in their daily life. A simple communication method using neuro-biological signal will be effective and helpful to enhance their life quality. In this study, a simple on-off communication method...
The paper presents an ongoing investigation of applying finite state machines (FSM) to drive a meal assistance robot based on electromyogram (EMG) signals. An adapting single-threshold method on EMG power is proposed to recognize different elevation gestures. Predefined control commands are output by FSM based on the extracted EMG features, and used to operate the robot. The performance of control...
Target position of a meal assistance orthosis is determined by using electrooculogram (EOG) signals and dish image. The meal assistance orthosis supports meal taking of disabled persons who have partly or completely lost the ability of moving their upper limbs by themselves independently. Scooping points on dishes can be determined by using image processing of the dish image taken by a video camera...
The objective of the present study is to determine if surface electromyography (EMG) signals can be used for controlling the motion of the meal assistance robot. The power of four EMG channels were calculated and encoded into five commands to track the motion of meal assistance robot. The results indicated that by using EMG signals, the meal assistance robot was able to follow the movement desire...
A meal assistance orthosis is developed for elderly and/or disable persons who have partly or completely lost the ability of moving their upper limbs by themselves independently. The meal assistance orthosis supports the disabled persons and brings foods from dishes to their mouth by their own forearms. Human intention, i.e., which foods they want to eat, can be extracted from electrooculogram (EOG)...
