Problems

Brightness: LEDs and OpticsPrice: $699+Applications: ?



Brightness and Power• More LEDs for illumination

Heat: Better thermal designs Cost: LEDs are expensive ! Size: Complex optics for multi-LEDs

• White boost Equivalent to transparent part of color wheel All 3 R,G,B LEDs on at the same time

• Blacks LED Dimming

• Limits Difficult to match lamp based, AC powered projectors Need to think about other applications



ApplicationsUnderstanding Projector Pro’s and Con’s

1. Large image with small device

2. Image overlay on real object– Ideal for augmentation

3. Superposition of images– Higher resolution, brightness

Issues Ambient bright light Screens: Affected by display surface reflectance



New Opportunities

Aware Projectors Decoupled display size



New Opportunities


Image Overlay on Real Objects Decoupled device Non-planar surfaces



New Opportunities



Machine Projection Projector for non-display apps

Stabilized Desktop-like Interaction

Sensor support What components are needed ?





Desktop-like Interaction

Mouse Simulation •Cursor follows handheld projector motion• Pre-warped image remains stable



Image Quasi-Stabilization

Eliminate hand jitter using inertial sensors+camera



Absolute Stabilization

Image stays registered with world features



New Opportunities






Changing Texture and Virtual Lighting

Directions for PocketProjector

‘Personal’ display• Shrinking portable devices that carry more data• Opportunity to switch between personal and public

Modular Low cost mass market product Will become building block

• Platforms: TV, Stereoscopic, Advertising, VideoWalls etc• Process: Tiling, Jittering, Superposition, Steering



Mitsubishi Pocket Projector

Mobility Limited Brightness but new Applications

All-in-one Display large with small device size Augment image overlay on real objects Communicate with tagged world (RFID, Sensors) Collaborate using shared projection
