This paper presents an interaction system with a floating display screen. Aerial imaging by retro-reflection (AIRR) forms an aerial LED screen that is floating over tabletop and is visible well over 120 degrees. In order to reduce latency, our system employs a high-frame-rate LED display and high-speed stereoscopic cameras. Developed system enables users to interact with aerially displayed information...
Sleep is an essential phase in human circadian rhythm with importance in restoring human vigour and vitality. Conventional sleep examination is done using Polysomnography with many sensors connected to various parts of human body. Recently, research in sleep is geared toward alternative feasibility of using only ECG signal. In this research, sleep stages classification using only features derived...
In this paper, a portable, easy to use, and real-time sleep stage classification device is presented. A simpler approach using raw features of ECG signals for sleep stage classification has been developed. Only one lead of ECG signal is required for operation which makes the device easily operable and only requiring user to attach 3 electrodes to the body. The device is constructed with singleboard...
An intuitive control system based on gesture recognition for humanoid robot has been developed. The gesture of a human operator can be recognized successfully with 99.87% accuracy using Fuzzy Neural Generalized Learning Vector Quantization (FNGLVQ) algorithm. A total of 13 distinct gestures were trained onto the system to represent 13 different actions. The system maps the recognized gestures to 13...
Countries such as Indonesia and Japan are prone to disasters. Telecommunication infrastructure are often damaged as a result of disasters, while reliable communication link is vital in search and rescue operation following a disaster. To overcome this problem, we developed swarm quadrotor robots capable of self-deployment and extending the coverage of available Wi-Fi network. Since most hand-held...
