LATENCY DETERMINATIONS FOR HUMAN INTERFACE DEVICES

Abstract:

In various examples, latency of human interface devices (HIDs) may be accounted for in determining an end-to-end latency of a system. For example, when an input is received at an HID, an amount of time for the input to reach a connected device may be computed by the HID and included in a data packet transmitted by the HID device to the connected device. The addition of the peripheral latency to the end-to-end latency determination may provide a more comprehensive latency result for the system and, where the peripheral latency of an HID is determined to have a non-negligible contribution to the end-to-end latency, a new HID component may be implemented, a configuration setting associated with the HID component may be updated, and/or other actions may be taken to reduce the contribution of the peripheral latency to the overall latency of the system.
