1. A ring-shaped wearable device for detecting finger movements, the wearable device comprising:

  • a ring-shaped frame defining a space to receive a wearing finger;

    an accelerometer coupled to the frame;

    a first proximity sensor coupled to the frame at a first position and facing a first direction, the first proximity sensor to detect proximity of a first finger on a first side of the wearing finger to the first proximity sensor;

    a second proximity sensor coupled to the frame at a second position and facing a second direction different than the first direction, the second proximity sensor to detect proximity of a second finger on a second side of the wearing finger opposite the first side of the wearing finger to the second proximity sensor;

    a two-dimensional displacement sensor coupled to the frame at a third position and facing a third direction, the third position being between the first position and the second position;

    a wireless communications transmitter coupled to the frame; and

    a data processor coupled to the frame, the data processor being operable to;

    receive input from the accelerometer, the first proximity sensor, the second proximity sensor, and the two-dimensional displacement sensor;

    generate a first output based on a first movement of the first finger detected by the first proximity sensor, the first output indicating selection of a first key of a virtual keyboard;

    generate a second output based on a second movement of the second finger detected by the second proximity sensor, the second output indicating selection of a second key of the virtual keyboard, the second key different than the first key; and

    cause the wireless communications transmitter to transmit the first output and the second output.
