The development of smart healthcare system has a potential to improve the quality of health services. Disabled patients need to express their needs non-verbally to their families or medical workers to fulfill their needs immediately. In this study, we developed hand gesture recognition using web camera as a notification system. Image acquisition was done on 12 subjects with various gender and ages. Based on human's basic daily needs, there are 5 gestures as the object of study: need to eat, need to drink, need to go to the toilet, need help and need medicines. The collected images were trained using Single Shot Detector (SSD) algorithm on MobileNet V2 architecture. Among the various deep learning techniques, SSD MobileNet V2 was chosen because it has good ability in object detection and needs low computation. Therefore, it is suitable to be applied on realtime detection. This study results on mean Average Precision (mAP) 44.7% and detection rate 85% which means 85 out of 100 images were well-detected. The mAP showed better result than previous studies. Frame rate per second (FPS) provided in this study was ±2 FPS. The gestures detected also triggered the notification on telegram to notify family or nurse who take care of disabled patients. © 2021 IEEE.
