Gesture recognition technology has been in use for decades. Predominantly, the technology has been used in motion and touch based models, however, in the last few years several consumer companies have begun adopting vision based models. The primary tracking technologies used for gesture recognition are camera, infrared, and ultrasound. Each tracking technique offers different benefits and limitations. ABI Research presents a clear overview of gesture recognition for mobile devices. This includes a summary of the strengths and weaknesses for each detection method. Additionally, gesture recognition penetration levels are presented within each key mobile device type with the key trends driving adoption. Finally, a Competitive Assessment is also provided for the key players in the gesture recognition space.
