Motion Interface – a Transformational Technology

Overview

Over the past 30 years, computing platforms have evolved from desktop personal computers to always-connected mobile smartphones. During that same period, computer interfaces have evolved from command line input via mice and keyboards to highly accurate and intuitive touchscreen interfaces.

Over the next 10 years, Motion Interface will enable a new era of computing where accurately tracking motion in free space and delivering this information as input commands to consumer electronics devices will drive advances in gaming, augmented reality, user interfaces based on gestures, Location Based Services (LBS), and health and fitness.

Motion Interface is a transformational technology that promises to have a significant impact on consumer products, very similar to some more recent transformational technologies like Bluetooth, Wi-Fi, Touch Screens and Camera Modules that have become pervasive in every consumer electronics products.

Motion Interface Use-Cases

Consumer applications for Motion Interface can be categorized into four applications: 1:1 Move, Gesture Interface, Pointing and Tracking.

1:1 Move

Device movement is used to control input in gaming or virtual reality applications such as aiming weapons in first-person shooter (FPS) console games, viewing three-dimensional panoramic images on a tablet, or navigating through virtual reality tourist locations on a mobile phone screen.

Gesture Interface

Gesture Interface allows using the device motion as a form of input command. It enables the device to interpret your motions as a command—for example you can answer your phone by a simple shaking of the device or unlocking it by drawing your initials in the air.

Pointing

Pointing enables new capabilities such as aiming a device to point-and-click content from a smart TV screen menu instead of using traditional up/down/left/right arrow keys, or pointing a smartphone towards a restaurant to view menu information and to make reservations.

Tracking

Tracking adds user orientation to GPS enabled devices and, when GPS signals are not available, enables accurate indoor pedestrian navigation to help you to find your destination. This is a vital function for providing accurate location based services and to help save device power by not having to perform continuous position locking through GPS, or Wi-Fi triangulation that leads to rapid battery drain.

InvenSense Advantages

InvenSense is the first company to deliver Motion Interface solutions with fully integrated sensors and robust MotionFusion™ firmware algorithms. Our MotionTracking™ devices enable our customers to integrate Motion Interface capability directly into devices easily and with minimal development cost and effort. We are the pioneer and thought leader in our industry, and have delivered many game changing solutions that have enabled this market. Beginning with our world’s first dual-axis MEMS gyroscopes in 2006 for the digital still camera market, to our world’s first integrated 3-axis motion processing solution for smart phones in 2009, to the world’s first single chip integrated 6-axis MotionTracking™ device in 2010, and the world’s first integrated 9-axis MotionTracking™ device in 2012.

Our MotionTracking™ devices offer significant performance, size, cost and functionality advantages as compared to discrete sensor solutions:
