Abstract
A display-enabled eyewear device has an integrated head sensor that dynamically and continuously measures or detects various cephalic parameters of a wearer's head. The head sensor includes a loop coupler system integrated in a lens-carrying frame to sense proximate ambient RF absorption influenced by head presence, size, and/or distance. Autonomous device management dynamically adjust or cause adjustment of selected device features based on current detected values for the cephalic parameters, which can include wear status, head size, and frame-head spacing.
Claims20
A device comprising:
- a device body configured to be supported, in use, on the head of a wearer of the device;
- one or more optical elements mounted on the device body such as to be supported within a field of view of the wearer during wear;
- a display mechanism configured to provide a near-eye display integrated in the one or more optical elements;
- a head sensor mechanism configured to measure ambient absorption characteristics of electromagnetic signals proximate the device body;
- and
- one or more computer processor devices that form part of onboard electronics and that are configured to perform operations comprising:
- based at least in part on the measured ambient absorption characteristics, deriving a cephalic parameter of a wearer on whose head the device is worn;
- and
- based at least in part on the derived cephalic parameter, implementing a management action with respect to the near-eye display.
6 more elements
A method comprising:
- using a head sensor mechanism incorporated in a head-worn device having an integrated near-eye display, measuring ambient absorption characteristics of electromagnetic signals proximate the device;
- using onboard electronics comprising one or more computer processor devices housed by the device, performing an automated procedure comprising:
- based at least in part on the measured ambient absorption characteristics, deriving a cephalic parameter of a wearer on whose head the device is worn;
- and
- based at least in part on the derived cephalic parameter, implementing a management action with respect to a near-eye display integrated in one or more optical elements mounted on the device.
