Abstract
Aspects of the present invention relate to external user interfaces used in connection with head worn computers (HWC).
Claims20
A method, comprising:
- generating a virtual line as digital content in a see-through display of a wearable head device;
- presenting the virtual line as a guide for alignment of pen strokes written by a wearer of the wearable head device;
- tracking a relative motion of a pen held by the wearer as the pen is moving along a surface when guided by the virtual line, wherein the tracking comprises:
- detecting, via an IMU located on the pen, movement of the pen;
- and
- capturing images of the pen as the pen moves relative to the virtual line, using a camera in the wearable head device;
- interpreting the relative motion of the pen to determine a written pattern, wherein interpreting the relative motion of the pen includes:
- determining, based on the IMU, a first relative motion between a tip of the pen and the virtual line;
- determining, based on the captured images, a second relative motion between a tip of the pen and the virtual line;
- and
- in accordance with a determination of a discrepancy between the first relative motion and the second relative motion, interpreting the relative motion of the pen based on the second relative motion.

A non-transitory computer-readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by one or more processors of one or more electronic devices, cause the electronic devices to:
- generate a virtual line as digital content in a see-through display of a wearable head device;
- present the virtual line as a guide for alignment of pen strokes written by a wearer of the wearable head device;
- track a relative motion of a pen held by the wearer as the pen is moving along a surface when guided by the virtual line, wherein the tracking comprises:
- detecting, via an IMU located on the pen, movement of the pen;
- and
- capturing images of the pen as the pen moves relative to the virtual line, using a camera in the wearable head device;
- interpret the relative motion of the pen to determine a written pattern, wherein interpreting the relative motion of the pen includes:
- determining, based on the IMU, a first relative motion between a tip of the pen and the virtual line;
- determining, based on the captured images, a second relative motion between a tip of the pen and the virtual line;
- and
- in accordance with a determination of a discrepancy between the first relative motion and the second relative motion, interpreting the relative motion of the pen based on the second relative motion.
