Abstract
Chording techniques are described that may be utilized in a variety of ways to provide inputs to a computing device. The computing device, for instance, may include sensors disposed on a housing of the computing device such that the sensors are configured to detect fingers of a user when grasping the device. Detection of a likely indexed relative position of the fingers of the user's hand in relation to each other, and even an amount of pressure used by respective ones of the fingers, may be used to define and input chords that may be used to initiate operations of the computing device.
Claims20
A method comprising:
- determining, by a computing device, based on a first group of inputs received from at least one sensor, a relative position of and an amount of pressure applied by each of a first group of fingers of a user who interacts with the computing device;
- identifying, by the computing device, based on the relative position of and the amount of pressure applied by each of the first group of fingers, a first chord in a sequence of chords, wherein the first chord defines a first substantially simultaneous collection of the first group of inputs received from the at least one sensor;
- determining, by the computing device, based on a second group of inputs received from the at least one sensor, a relative position of and an amount of pressure applied by each of a second group of fingers of the user who interacts with the computing device;
- identifying, by the computing device, based on the relative position of and the amount of pressure applied by each of the second group of fingers, a second chord in the sequence of chords, wherein the second chord defines a second substantially simultaneous collection of the second group of inputs received from the at least one sensor;
- and
- responsive to determining that the first and second chords in the sequence of chords are associated with one or more operations of the computing device, initiating, by the computing device, the one or more operations.
A system comprising:
- a housing;
- at least one sensor coupled to the housing;
- and
- one or more processors configured to:
- determine, based on a first group of inputs received from the at least one sensor, a relative position of and an amount of pressure applied by each of a first group of fingers of a user who interacts with the computing device;
- identify, based on the relative position of and the amount of pressure applied by each of the first group of fingers, a first chord in a sequence of chords, wherein the first chord defines a first substantially simultaneous collection of the first group of inputs received from the at least one sensor;
- determine, based on a second group of inputs received from the at least one sensor, a relative position of and an amount of pressure applied by each of a second group of fingers of the user who interacts with the computing device;
- identify, based on the relative position of and the amount of pressure applied by each of the second group of fingers, a second chord in the sequence of chords, wherein the second chord defines a second substantially simultaneous collection of the second group of inputs received from the at least one sensor;
- and
- responsive to determining that the first and second chords in the sequence of chords are associated with one or more operations of the computing device, initiate the one or more operations.
