Texture on Touch Screens

This sounds great - and I'm looking ahead to the day that HTML supports a touch screen box commany with haptic feedback for the blind (and the overworked computer professional). Not only can this be used to confirm button presses, it can also be used to locate the button on a touchscreen quickly by feel rather than by sight. I'm guessing that the first meaningful applications will be in enhancing the machine-user interface and that the ability to have textured graphics and more interactive games will be an interesting bonus.

We are hearing about  Haptics for a couple of years now from various reasearch labs - Haptic feedback sensors, Haptic feedback display and so on.

When can we expect a real commercial product using such technologies?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
