Detecting Twist Input with an Interactive Cord

A system comprising:

• an interactive cord, the interactive cord comprising:
• an inner layer comprising a cable and a first set of conductive yarns wrapped around the cable in a first direction and an outer layer comprising a second set of conductive yarns wrapped around the inner layer in a second direction that is opposite the first direction, wherein twisting the interactive cord in an opposite direction from the second direction causes a distance between the first set of conductive yarns and the second set of conductive yarns to increase thereby decreasing capacitance values;
• and
• a controller coupled to the interactive cord, the controller configured to:
• determine that a change in the capacitance values corresponds to a twist input received by the interactive cord;
• determine that a direction of the twist input is the opposite direction from the second direction based on a decrease in the one or more capacitance values;
• and
• initiate a function in response to the determination that the direction of the twist input is the opposite direction from the second direction.

A system comprising:

• an interactive cord, the interactive cord comprising:
• an inner layer comprising a cable and a first set of conductive yarns wrapped around the cable in a first direction and an outer layer comprising a second set of conductive yarns wrapped around the inner layer in a second direction that is opposite the first direction, wherein twisting the interactive cord in a same direction as the second direction causes a distance between the first set of conductive yarns and the second set of conductive yarns to decrease thereby increasing capacitance values;
• and
• a controller coupled to the interactive cord, the controller configured to:
• determine that an increase in capacitance values corresponds to a twist input received by the interactive cord;
• determine that a direction of the twist input is the same direction as the second direction based on an increase in the capacitance values;
• and
• initiate a function in response to the determination that the direction of the twist input is the same direction as the second direction.

A method implemented by a controller coupled to an interactive cord that includes a cable and a first set of conductive yarns configured as transmitting lines that are wrapped around the cable in a first direction and a second set of conductive yarns that are wrapped around the cable in a second direction, wherein twisting the interactive cord in a direction that is opposite the second direction causes a distance between the first set of conductive yarns and the second set of conductive yarns to increase thereby decreasing capacitance values, the method comprising:

• determining that a decrease in capacitance values corresponds to a twist input received by the interactive cord;
• determining that a direction of the twist input is the direction that is opposite the second direction based on the decrease in the capacitance values;
• and
• initiating a function in response to determining that the direction of the twist input is the direction that is opposite the second direction.
