Abstract
The following quote was obtained by the news editors from the background informa tion supplied bythe inventors: “Head mounted face tracking is conventionally do ne using cameras. But cameras can haverelatively high-power and data throughput budgets, which is not ideal for form factors which have limitedpower and compu te budgets (e.g., headsets). Moreover, orientation of cameras for face tracking can resultin issues with occlusion caused by, e.g., facial hair of the user, or improper line of sight.”
