As good as current touchscreen technology is, there’s still quite a bit of lag between your actual finger swipes and the time that it takes for the screen to show what you’ve written. Latency is the enemy here – the lower the latency, the more responsive the screen becomes. Microsoft wants that particular issue to be a thing of the past, and has demoed an ultra-high performance touchscreen with an extremely low latency of 1ms, which compared to typical 100ms touchscreens, is a huge leap forward. Unfortunately it’s not known if Microsoft made the touchscreen as a mere proof of concept device or their actually pushing to get this kind of tech into our tablets and smartphones soon. Until then you can view the astounding performance of the tech in the video linked below.
