Sensor fusion algorithm

Abstract

Sensor fusion algorithm techniques are described. In one or more embodiments, behaviors of a host device and accessory devices are controlled based upon an orientation of the host device and accessory devices, relative to one another. A combined spatial position and / or orientation for the host device may be obtained based on raw measurements that are obtained from at least two different types of sensors. In addition, a spatial position and / or orientation for an accessory device is ascertained using one or more sensors of the accessory device. An orientation (or position) of the accessory device relative to the host computing device may then be computed based on the combined spatial position / orientation for the host computing device and the ascertained spatial position / orientation for the accessory device. The relative orientation that is computed may then be used in various ways to control behaviors of the host computing device and / or accessory device.

AI Technical Summary

Problems solved by technology

For example, the main computing device may have limited control over how the accessory device behaves, so the actions of the accessory device may sometimes interfere with the operation of the main computing device

Also, user experience may be adversely affected by accessory devices that do not respond in a consistent manner with the primary computing device

Therefore, comprehensive management of accessory device behavior and interactions can be a challenging consideration for developers of mobile computing devices
