Wrist-worn device-based inputs for an operating system

A first device, comprising:

• a processing system comprising a processing device and computer storage;
• the computer storage storing computer program instructions which define an operating system which, when processed by the processing system, provides an operating system of the first device, the operating system having an interface defining inputs of the operating system;
• the computer storage further storing computer program instructions which define a device driver which, when processed by the processing system, provides a device driver for the second device in the first device, the device driver being configured to:
• receive, from the second device, data based on a biopotential signal originating from a top of a wrist of a person and related to activity of muscles of a hand of the person and data based on a location signal originating from the top of the wrist and indicative of a location of the top of the wrist, and
• associate a primitive gesture with an input of the operating system, the primitive gesture comprising a pose of the hand of the person and a location of the top of the wrist of the person, the primitive gesture having been detected based on the biopotential signal and the location signal.

An apparatus, comprising:

• a biopotential sensor configured to be worn at a top of a wrist on a body of a person and configured to sense biopotentials at the top of the wrist related to activity of muscles of a hand of the person, the biopotential sensor providing as an output a biopotential signal indicative of the sensed biopotentials;
• and
• a location sensor constructed to be worn at the top of the wrist on the body of the person and configured to sense a location of the top of the wrist of the person, the location sensor providing as an output a location signal indicative of the sensed location;
• and
• a processing system comprising a processing device and computer storage;
• the computer storage storing computer program instructions which define an operating system of the processing system which, when processed by the processing system, provides an operating system, the operating system having an interface defining inputs of the operating system;
• the computer storage further storing computer program instructions which, when processed by the processing device, configure the processing system to:
• receive data based on the biopotential signal and data based on the location signal, and
• associate a primitive gesture with an input of the operating system, the primitive gesture comprising a pose of the hand of the person and the location of the top of the wrist of the person, the primitive gesture having been detected based on the biopotential signal and the location signal.
