CoolSo is wearable gesture input device that can be sold with virtual reality (VR) or augmented reality (AR) products, and used to create a more immersive, interactive VR/AR interface. It allows users to “reach out” and interact with the virtual world around them by utilizing signals from muscle movement as a source for gesture control. Unlike the transmission of EMG signals from the nerve action potential to the skin, this technology reads the vibrations produced from the friction of muscle fibers and the perimysium during muscle contractions. It is capable of measuring muscle movement characteristics and can use the bodily motion signals of others as a signal processing method filter differentiation. The technology also resolves problems of sunlight interference with the image recognition technology. Because of their operability and extended use (1.5 hours or longer), products in the gaming industry must react rapidly (<0.1 sec) and be able to function for long periods of time, without being affected by environmental changes. Because CoolSo measures vibration signals and does not require attaching any electrodes to the skin, it is unaffected by perspiration, overcoming post-perspiration signal interference issues.
