• Eye Relief ~20mm, Eye-Box ~10mm
• Brightness: 3 to 5kCd/m² (nits), Decent FOV (depends on application)
• Image Position (at finite or at infinite distance), Flip Vu recommended
• Optimal Convergence for Binoculair systems
• Light Weight<100g & Ophtalmic Correction mandatory

14. UX for Smart Glasses, The Key success factor for AR devices
14
• Touch pad:
 Virtual keyboard
 Deported Keyboard on smart phone screen
• Voice command:
 Off line Voice command
 On Line Voice command
 Noise Cancellation (2 embedded Mic mandatory)
 Still very sensitive with low sucess rate
• Gyroscopic:
 Head Mouvement, still not natural
 Difficult to get precise gesture
 Social acceptability issue
• Camera Gesture recognintion:
• Hands movements tracking by TOF Cameras
• Implies the use for one to Two cameras all time (power consumption, cpu resource)
• Visual, Or Eye Tracking:
• BY imaging and tracking of eye and pupil position with low resolution camera
• Still dificult to get very high precision, used for eye to display calibration
• Could induces eye fatigue
• But it should be the best for the future

15. Future trend in AR
headsets and Smart
glasses

16. • AR to replace VR in the longer term:
• If the Display could be transparent, it should transparent to allow
full user’s Mobility
• Form factor is not necessary Glasses Like
• For a better comfort
• For a better social acceptability (Wearable device)
• In the technology side:
• Better Display:
• Higher FOV is expected with >50 deg
• Light Field to display information in different focus plane
• Small foot print with probably Light guide based technologies
• Better computing platform
• Optimized Chip for low power consumption & low heating
• More hardware integration
• Needs for a better Battery (Life time, capacity, form factor)
• UX/Software side: Here is the big value
• Create a new eco-system (Mobile phone app like)

Use Case

19. 19
Demand for smart glasses
will be driven by enterprises more than
consumers… in the short term
• Enterprise market for wearables to surpass consumer market,
according to Deloitte’s Consulting
• Good ROIs can be demonstrated in enterprises (productivity
of hands free and information access)
• There are millions of field service, warehouse, maintenance
and other enterprise users that
will benefit from hands free smart glass solutions
