Wearable muscle interface systems, devices and methods that interact with content displayed on an electronic display

A wearable system that in use provides hands-free access to and control of a portable electronic display, the wearable system comprising:

• i) a wearable muscle interface device comprising:
• a plurality of muscle activity sensors to be worn on an arm of a user, the muscle activity sensors responsive to signals generated by muscles in the arm of the user;
• and
• a transmitter communicatively coupled to the plurality of muscle activity sensors, wherein in use the transmitter transmits at least one signal from the wearable muscle interface device based on the signals detected by the muscle activity sensors;
• and
• ii) a wearable head-mounted display comprising:
• at least one display screen to be worn on a head of the user, the at least one display screen arranged to be positioned in front of at least one eye of the user when worn on the head of the user;
• a receiver communicatively coupled to the at least one display screen, wherein in use the receiver directly receives the at least one signal transmitted from the transmitter of the wearable muscle interface device;
• and
• a processor communicatively coupled to the receiver and to the at least one display screen, wherein in use the at least one signal received directly from the transmitter of the wearable muscle interface device by the receiver of the wearable head-mounted display effects control of at least one function of the wearable head-mounted display.

A method of using a wearable system to achieve hands-free access to and control of a portable electronic display, wherein the wearable system includes a wearable muscle interface device and a wearable head-mounted display, the method comprising:

• detecting muscle activity corresponding to a physical gesture performed by a user of the wearable system by at least one muscle activity sensor of the wearable muscle interface device;
• transmitting at least one signal from the wearable muscle interface device by a transmitter of the wearable muscle interface device based at least in part on the muscle activity detected by at least one muscle activity sensor of the wearable muscle interface device;
• receiving the at least one signal directly from the wearable muscle interface device by a receiver of the wearable head-mounted display;
• processing the at least one signal by a processor of the wearable head-mounted display;
• and
• effecting at least one interaction between the user and the wearable head-mounted display by the processor of the wearable head-mounted display based on the processing of the at least one signal by the processor of the wearable head-mounted display.
