Small Flexion Movement Detection System of the Index Finger and Its Applications

Abstract

Some ALS and SMA patients are concerned about the inability to communicate emergencies such as sudden changes in their health in the absence of helpers or family members. This paper presents the development of an emergency call system for a real user, which uses hand pose estimation to detect a small flexion movement of the index finger of the right hand, and then uses the results to notify the helpers or family members of an emergency. Experimental results show that real user can send notifications through the system and the time required is within an acceptable range.
