Abstract
Devices connected with a computer system are interrogated to detect whether they are configured and functioning. In an audio device implementation, a known audio sample is output to a loudspeaker. If the loudspeaker is properly configured and functional, an attached microphone will capture the sound corresponding to the audio sample generated by the loudspeaker. If sound corresponding to the audio sample is detected, an indication is provided to the user that the microphone and loudspeaker are operational. If no sound corresponding to the audio sample is detected, an indication is provided to the user that the loudspeaker is not enabled and additional configuration is required.
Claims20
A method for detection of configuration of a device connected with a computer system, the method comprising:
- for each configuration connected with the computer system,
- transmitting a sample signal for output via an output device connected with the computer system,
- capturing a captured signal via an input device connected with the computer system, and
- comparing the sample signal to the captured signal to determine whether the captured signal correlates to the sample signal thus indicating whether the output device, the input device, or both are functional.
A method for detecting a configuration of a microphone or a loudspeaker connected with a computer system, the method comprising:
- (a) transmitting a sample audio signal from a sample audio file stored in a memory of the computer system for output via the loudspeaker;
- (b) capturing a captured sound via the microphone to produce a captured audio signal;
- and
- (c) confirming if the microphone, the loudspeaker, or both are functional when the sample audio signal correlates with the captured audio signal;
- and
- (d) automatically iterating (a), (b), and (c) for each other configuration connected with the computer system, when the sample signal and the captured signal do not correspond substantially, to select a configuration where a sample signal and a captured signal correlate for that configuration.
A computer system for automatic detection of configuration of a device connected with the computer system, the computer system comprising:
- a processor;
- a memory accessible by the processor and having a sample file;
- a plurality of output devices under control of the processor of which each output device is capable of outputting a sample signal corresponding to the sample file;
- a plurality of input devices under control of the processor of which each input device is capable of receiving a captured signal corresponding to the sample signal output by an output device in a same configuration;
- and
- a device detection module under control of the processor that receives, for each configuration, both the sample signal from the output device and the captured signal from the input device and is adapted to compare the sample signal to the captured signal for each configuration to determine whether the captured signal substantially corresponds to the sample signal to determine whether the output device, the input device, or both are functional until a configuration is located where the sample signal and the captured signal correlate for that configuration.
