Touch sensors for interactive objects with input surface differentiation

An interactive object wearable by a user, comprising:

• a touch sensor comprising a plurality of parallel sensing lines elongated in a first direction with a separation therebetween in a second direction orthogonal to the first direction, the plurality of parallel sensing lines comprising a first subset of parallel sensing lines coupled to an input surface and a second subset of parallel sensing lines coupled to a second surface and separated in a third direction orthogonal to the first direction and the second direction, wherein the input surface is configured to receive inputs from the user and the second surface is adjacent to at least a portion of the user when the interactive object is worn by the user;
• one or more control circuits in communication with the touch sensor, the one or more control circuits are configured to:
• detect a touch input to the touch sensor and generate touch data indicative of a response to the touch input by at least one parallel sensing line of the first subset of parallel sensing lines and a response to the touch input by at least one parallel sensing line of the second subset of parallel sensing lines;
• classify the touch input as associated with the input surface or the second surface based at least in part on a comparison of the response to the touch input by the at least one parallel sensing line of the first subset of parallel sensing lines with the response to the touch input by the at least one parallel sensing line of the second subset of parallel sensing lines;
• and
• in response to classifying the touch input as associated with the input surface, identify a gesture associated with the touch input based at least in part on the response to the touch input by the least one parallel sensing element of the second subset of parallel sensing lines.

A computer-implemented method of managing input at an interactive object, the method comprising:

• obtaining, by one or more processors, touch data associated with a touch sensor comprising a plurality of parallel sensing lines elongated in a first direction with a separation therebetween in a second direction orthogonal to the first direction, the plurality of parallel sensing lines comprising a first subset of parallel sensing lines coupled to an input surface and a second subset of parallel sensing lines coupled to a second surface and separated in a third direction orthogonal to the first direction and the second direction, wherein the input surface is configured to receive input from a user and the second surface is adjacent to at least a portion of the user when the interactive object is worn by the user;
• detecting, by the one or more processors, a touch input to the touch sensor;
• generating, by the one or more processors, touch data indicative of a response to the touch input by at least one parallel sensing line of the first subset of parallel sensing lines and a response to the touch input by at least one parallel sensing line of the second subset of parallel sensing lines;
• classifying, by the one or more processors, the touch input as associated with the input surface or the second surface based at least in part on a comparison of the response to the touch input by the at least one parallel sensing line of the first subset of parallel sensing lines with the response to the touch input by the at least one parallel sensing line of the second subset of parallel sensing lines;
• and
• in response to classifying the touch input as associated with the input surface, identifying a gesture associated with the touch input based at least in part on the response to the touch input by the least one parallel sensing element of the second subset of parallel sensing lines.
