OVERVIEW

Hillcrest Labs MotionEngine™ is CEVA’s core sensor processing software system and is the product of over 15 years of experience developing sensor-based technology and products. MotionEngine is packaged into the application-specific software products described below and powers the BNO, FSP, and FSM hardware product lines. The software combines high accuracy 6-axis and 9-axis sensor fusion, dynamic sensor calibration, and many application specific features such as cursor control, gesture recognition, activity tracking, context awareness, and AR/VR stabilization to name a few.

MotionEngine software is compatible with the leading embedded processing architectures and operating systems and can be delivered as either a library or a full chip binary with host drivers that dramatically simplify system integration.

The application-specific features are packaged into MotionEngine software products that, when combined with a variety of off-the-shelf inertial and environmental sensors, provide sensor processing solutions for applications that demand the highest accuracy and quality. These are packaged into products for Hearables, XR, Robotics, TV and Set-top box, Handheld Motion Controllers, Health & Fitness, and PC & Mobile segments – including stylus pens – and may be customized for large customers.

 

To better accommodate our customers, we have developed specialized software packages for the markets that we serve:

 

MotionEngine™ Hear

In-ear and over-ear electronics like TWS, audio headsets, hearing aids, and AR glasses all have one thing in common: they can benefit from gesture interface. But existing products have failures that frustrate users. MotionEngine Hear’s tap gestures and in-ear detection make taking control of that audio easier and more fluid. On top of that, built-in activity classifiers add to a dynamic list of features that informs intelligent automated decision making, while 3D head tracking enables immersive spatial audio.

 

MotionEngine™ Robotics

Automated robots need to move intelligently through their spaces, and our inertial measurement unit (IMU) sensor fusion algorithms ensure they can. After all, a robot’s convenience is based on its autonomy. Our algorithms achieve precise heading with minimal drift. Our interactive and dynamic calibration algorithms achieve performance right out of the box and over time and temperature.

 

MotionEngine™ Scout

Intelligent automated robots use complex Simultaneous Localization and Mapping (SLAM) algorithms to determine a robot’s location. MotionEngine Scout determines a robot’s position with the fusion of IMU, wheel encoder, and optical flow sensor data. This removes the reliance on cameras and LIDAR systems and adds robustness under crucial circumstances where typical visual sensors would fail.

 

MotionEngine™ SmartTV

Did you ever wish your customers could more efficiently interact with your displays? The SmartTV package enables this by utilizing natural hand motion and translating it intuitively on displays. Movement feels natural with features like cursor control, orientation compensation, gestures, and virtual controls.

 

 

MotionEngine™ Air

Handheld controllers deserve more than antiquated button interfaces. Today, cursor and gesture controls can be easily added to enhance interactivity. MotionEngine™ Air enables the similar cursor capability as in SmartTV, but also enables unique gestures (like twist, flip, pick-up) to help streamline workflows whether you’re presenting, creating, or controlling.

 

 

MotionEngine™ Mobile

As our desires for more “smart” devices has increased, so has their power consumption. MotionEngine Mobile delivers high performance, low power, sensor independent motion processing for mobile devices. This can be used to power motion applications, provide context awareness, activity tracking, and even pedestrian navigation. This software is versatile enough for smartphones, tablets, wearables, and IoT devices.
