US 2026/0099212 A1 · INFORMATION HANDLING SYSTEM KEYBOARD-TO-PEER DIRECT CONTROL BY ULTASOUND COMMANDS

Abstract

An information handling system keyboard includes a speaker that generates ultrasonic sounds as control signals that provide direct control to peer devices from the keyboard, such speakers, headsets and web cameras. Commands are communicated as ultrasonic pulses of different lengths that identify zeros and ones in bytes of commands and received at a microphone of the peer device. In one embodiment, a doppler gesture detection device speaker is leveraged to send commands and peer devices receive the commands with speakers having other functions at the peer device so that direct peer commands from the keyboard are extended with existing hardware devices leveraged to a new function.

Dependent claims

An information handling system comprising:

a housing;
a processor coupled in the housing and operable to execute instructions to process information;
a memory coupled in the housing and interfaced with the processor, the memory operable to store the instructions and information;
a peer device separate from the housing and having a microphone, the peer device configured to perform a function that includes the microphone;
and
a peripheral keyboard separate from the housing and interfaced with the processor, the keyboard having plural keys each key accepting an end user press as an input, the keyboard having a speaker configured to play ultrasonic pulses in response to a peer device control input at the keyboard, the ultrasonic pulses received directly by the peer device microphone and applied as commands to adjust the peer device function.
