In today’s digital home, audio/video remotes require a simpler, more intuitive user interface to perform in one gesture what would have taken 6-10 mechanical button clicks to control and access content. 3D remote products can be used to simplify the navigation through screens, photos, music lists and other media. MEMS gyroscopes are used to provide a jitter-free, low-latency motion-based user experience due to their ability to deliver critical rotational information free of interference from magnetic fields and linear acceleration. As opposed to accelerometers and magnetic sensors, gyroscopes do not rely on external forces to measure the motion. They are the only sensors that can process motion completely independent of any external forces by providing their own vibrating energy source.
Key requirements for the dual-axis gyros used in remote control devices include low cost, low bias drift and high shock tolerance. The InvenSense IDG-500 and IDG-650 Dual Axis MEMS Gyroscopes meet these requirements with its 4x5x1.2mm package size, auto-zero feature and 10,000g shock rating.
The IDG-500™ is ideal for remote control applications, while the IDG-650™ is ideal for converged remote control/game controller applications, both of which offer the industry’s smallest dual-axis MEMS gyroscope design with integrated signal conditioning. Optional ISZ-500™ and ISZ-650™ single-axis (Z) gyroscopes are available to complement the IDG-500 dual-axis (X/Y) and IDG-650 dual-axis (X/Y) gyros, respectively, for a solution where all sensors mount in-plane with the other system electronics.
