The Touch Guys Missed Something
The Touch Guys are Clueless
Most Interactive Breakthroughs Came from Someone Other than Touch Guys
Examples
George Hurst, founder of Elographics, was trying to make a digitizer.
Bill Pepper, developer of original analog S-Cap touch screen, was trying to make a fretless, stringless guitar.
John Fenn and Daryl Stoddard, inventors of the first matrix touch panel, were making an electronic chess board.

3. Great Optics
4. Unbreakable/All Plastic
5. Contoured and formed
6. Lots of electronics options
7. Low cost
8. Low power
9. Proximity Sensing (Z-axis)
10. No Coordinate Drift
11. High Resolution
12. Pen Input

Reflecting on the Past and Looking to the Future
Questions to Ask
We had interactivity at our fingertips in 1920. Why did it take so long to get to where we are today?
How do we apply what we know today, with what we missed in the past, to get to where we want to be in the future?

Why the Touch Guys Missed the Boat
First Miss: Durability
In the early 80's there were three touch technologies
IR
Resistive
Zone capacitive

Why the Touch Guys Missed the Boat
Second Miss: Multi-Touch
Multi-touch was rejected for about 25 years due to ghosting.

Why the Touch Guys Missed the Boat
2 million Projected Capacitive Verifone units were shipped pre-iPhone, but no one realized the display’s potential until Apple.

Putting the Past, Present & Future Together
How do you combine thecapabilities of the Theremin &
PCAP with our dreams of interactivity?

Putting the Past, Present & Future Together
Disney Research has Figured out the Solution
PCAP + Gestures + Motion = Touché
Touché = Swept Frequency Capacitive Sensing

Putting it All Together
Bottom Line
Interactivity should not be confined to just touch.
Think Bigger.
Next Steps
Touch guys need to go back to the drawing board and look at the technology at our fingertips since 1920 and look to combine with the PCAP of today.
Non-touch guys should channel their inner Disney.
