Production-ready software for gesture control and 3D motion tracking
Markets for gesture control and 3D motion tracking include smartphone and PC stylus pens, smart TV and over-the-top (OTT) remote controls, game controllers, AR and VR controllers, and PC peripherals.
The global market for Bluetooth® and other wireless handheld controllers is expanding rapidly with more than 500 million RF devices expected to ship in 2022. New advancements in low power inertial sensors and Bluetooth Low Energy along with the MotionEngine Air sensor fusion software yields sub-milliamp level power draw for the whole system. This enables the proliferation of precise, interactive and intuitive motion-control for always-on and always-aware user experiences.
Some key features of MotionEngine Air include precise pointing, gesture and motion control algorithms that feature cursor for point-and-click control of an onscreen UI; gestures such as flick, shake, tap, tilt, rotate, or circle for intuitive UI controls; 6-axis sensor fusion enabling 3D motion tracking for gaming and VR; and Motion events such as pick-up, flip and stability detector to enable power savings.
MotionEngine Air benefits from patented orientation compensation and adaptive tremor removal, required for a consistent and intuitive user experience.
Pre-qualified for use with sensors from the leading inertial sensor suppliers MotionEngine Air includes a comprehensive software stack with host drivers and sensor management to streamline software integration with widely used operating systems including Android, Windows, MacOS and Linux. An Arm Cortex-M based evaluation board and related firmware are available.
MotionEngine Air software is a highly flexible, low power and small memory footprint solution that can run on a variety of processors, including Arm Cortex-M, RISC-V and CEVA-BX and CEVA-TeakLite families of DSPs. It can be delivered in multiple configurations – including a full-featured system that requires an accelerometer plus gyroscope (IMU) and a gesture and motion event-based solution that requires only an accelerometer.
Chad Lucien, Vice President and General Manager of the Sensor Fusion Business Unit at CEVA, commented: “The Hillcrest Labs MotionEngine Air solution combines the most compelling features we’ve created in the 15 years since we pioneered the use of MEMS inertial sensors in remote controls. This new product makes it possible for OEMs and ODMs to easily integrate the software into an off-the-shelf RF SoC or MCU to run directly on a battery-powered controller. This opens the door for many different mobile, PC, TV, AR/VR, game and enterprise peripherals to use precise motion controls to enhance a wide variety of user experiences.”
CEVA will demonstrate its MotionEngine Air software and evaluation board during CES 2020.
