The one or more processors identify a companion device electronically in communication with the wireless communication device as being a wearable glass projection device when a received extended display identification (EDID) extension(s) from the companion device include a non-zero field of view, pixel density, and/or interpupillary distance value. The one or more processors can render content for the wearable glass projection device as a function of the non-zero field of view, pixel density, and/or interpupillary distance value, and can optionally apply a rendering adjustment to the content as a function of optical data associated with a user of the electronic device stored in the non-transient memory device. ## Claims ### Claim 1 An electronic device, comprising: a communication device;
