User interface sound emanation activity classification

A system comprising:

• a memory;
• at least one processor in communication with the memory;
• and
• program instructions executable by one or more processor via the memory to perform a method comprising:
• obtaining an audio input, the audio input representing sound emanating from a key press based user interface;
• generating a context pattern based on the audio input;
• performing classification of the context pattern to classify the context pattern as belonging to a signature pattern classification, wherein the signature pattern classification specifies a user activity;
• and
• providing an output based on the performing classification, wherein the performing classification results in classification failure, wherein the method includes prompting a user to enter activity information in response to the classification failure, and wherein the prompting includes providing user interface functionality that prompts the user to enter activity specifying information that specifies an activity engaged in by the user resulting in the generating of the context pattern, and wherein the method includes, using data received from the user in response to the prompting, registering the context pattern as a new signature pattern for comparison to subsequent context patterns.

A computer program product comprising:

• a computer readable storage medium readable by one or more processing unit and storing instructions for execution by one or more processor for performing a method comprising:
• obtaining an audio input, the audio input representing sound emanating from key presses of a key press based user interface;
• generating a context pattern based on the audio input;
• performing classification of the context pattern to classify the context pattern as belonging to a signature pattern classification, wherein the signature pattern classification specifies a user activity, the user activity involving use of keys of the key press based user interface;
• and
• providing an output based on the performing classification, wherein the performing classification results in classification failure, wherein the method includes prompting a user to enter activity information in response to the classification failure, and wherein the prompting includes providing user interface functionality that prompts the user to enter activity specifying information that specifies an activity engaged in by the user resulting in the generating of the context pattern, and wherein the method includes, using data received from the user in response to the prompting, registering the context pattern as a new signature pattern for comparison to subsequent context patterns.
