1. A human interface device (HID) operable to communicate via a wireless link, the device comprising:
- a sensor configured to detect user activity associated with the HID;
a controller coupled to the sensor, the controller configured to perform the following during each of a plurality of detection periods;
exit, for at least a portion of the HID, a low-power state; and
identify user activity detected by the sensor; and
a wireless interface coupled to the controller, the wireless interface configured to transmit a message comprising a combined activity report that indicates the identified user activity from at least two detection periods.

12. A method of operating a host computer that receives user activity messages from a human interface device (HID) via a wireless link, the method comprising:
-
during operation of an application program being executed on a host computer, receiving at the host computer a message from a human interface device (HID) via a wireless link, the message comprising a combined activity report indicating information about a first user activity detected by the HID for a first detection period and information about a second user activity detected by the HID for a second detection period subsequent to the first detection period; updating the application program in response to the first user activity information; and updating the application program in response to the second user activity information. - View Dependent Claims (13, 14, 15)
