Abstract
Aspects of the present disclosure relate to external user interfaces used in connection with head worn computers (HWC). Embodiments relate to an external user interface that has a physical form intended to be hand held. The hand held user interface may be in the form similar to that of a writing instrument, such as a pen. In embodiments, the hand held user interface includes technologies relating to writing surface tip pressure monitoring, lens configurations setting a predetermined imaging distance, user interface software mode selection, quick software application launching, and other interface technologies.
Claims22
A system comprising:
- a device including:
- a hand-held housing including a tip;
- an optical device including a first lens and an image sensor;
- a cover lens positioned over the first lens, wherein the cover lens is located at a distal end of the tip;
- and
- an inertial measurement unit (IMU);
- and
- one or more processors adapted to perform a method comprising:
- detecting, via the IMU, a location of the tip with respect to a first point of a surface external to the device;
- detecting, via the image sensor, an image of the surface at the first point;
- and
- determining, based on the detected location of the tip and the detected image of the surface at the first point, an input command provided by a user;
- wherein:
- the cover lens is configured to maintain, during a motion of the tip, a first distance between the surface and the image sensor, and
- the image sensor detects the image of the surface through the first lens and the cover lens, wherein the cover lens has a nonzero optical power.
A method comprising:
- determining a tip of a hand-held device is positioned on a surface external to the device, wherein the device comprises:
- an optical device including a first lens and an image sensor;
- a cover lens positioned over the first lens, wherein the cover lens is located at a distal end of the tip;
- and
- an inertial measurement unit (IMU);
- detecting, via the IMU, a location of the tip with respect to a first point of the surface external to the device;
- detecting, via the image sensor, an image of the surface at the first point, wherein the image is detected through the first lens and the cover lens, wherein the cover lens has a non-zero optical power;
- and
- determining, based on the detected location of the tip and the detected image of the surface at the first point, an input command provided by a user.
