Power efficiency based on a dynamic report rate

Abstract

A method and system configured to receive a first report from a computer peripheral device by a receiver, determine that the first report is corrupted or received at a rate slower than the first report rate, compute a current trajectory of the computer peripheral device based on one or more intervals of movement data in the first report, compute a predicted trajectory of the computer peripheral device based on the first report, compute an incremental displacement of the computer peripheral device based on the predicted trajectory. The method and system can further generate data indicative of a position or displacement of the computer peripheral device based on the predicted trajectory of the computer peripheral device and send the data indicative of a position or displacement of the computer peripheral device at an interval that is less than twice a period of the first report rate to the host computing device.

AI Technical Summary

Benefits of technology

The patent describes a method for accurately tracking the movement of a computer peripheral device, such as a mouse, using a motion sensor and an inertial measurement unit (IMU). The method involves receiving a first report from the peripheral device, which includes movement data generated by the device, and predicting the trajectory of the device based on the movement data. The predicted trajectory is then used to determine the position or displacement of the device at various intervals. The method can be implemented using a state estimator or a linear or extended Kalman filter to incorporate estimated error. The technical effect of this patent is to provide a more accurate and reliable means for tracking the movement of a computer peripheral device.

Problems solved by technology

Many of these peripheral devices employ wireless communications protocols to provide the user with flexibility and convenience, however traditional wireless communications protocols can experience a relatively significant time delay between when a user interacts with a peripheral device and when the host recognizes the interaction (also referred to as “latency” herein).

However, fast report rates (e.g., human interface commands, or “HID” commands) are often associated with a corresponding high power consumption that may result in low battery life in some wireless peripheral devices, which may be unacceptable for more discerning gamers.

Furthermore, in some instances, reliably maintaining a fast report rate may be challenging due to wireless interference, jitter, or other deleterious phenomena, which can cause report rates to vary beyond certain desirable specifications.
