Cool! Touchscreen Computers You Don't Even Need to Touch

A bit about some research at MIT. Simply make a "gesture" with your hand and the screen responds.

From the Article

The popularity of touch-screens on mobile phones means that a swipe, tap or a flick comes as naturally these days as the click of a mouse. But existing touch-screens have their limits. Those relying on changes in electrical resistance tend to have poorer resolution than is needed for modern applications, while those that rely on capacitance require an ungloved finger.

Consequently, a new generation of touch-screens, known as optical liquid crystal displays, is emerging. Optical LCDs embed tiny light sensors next to many of the screen’s pixels. In the brief moments between each successive screen image, the backlight is turned off. In these periods of darkness, undetectable to the human eye, sensors are able to pick up light coming from outside the device.

[Snip]

If the principle can indeed be extended to devices that employ optical LCDs, screens of the future will be able to harness the power of mere gestures. Zooming in on an image, and then out again, will be as easy as moving a hand closer or further away from the screen. A hovering finger or a simple movement will be able to press virtual buttons.

These features will, no doubt, be of particular appeal to those who dislike the perpetually greasy and smeared appearance of touch-screen computers and mobile phones. So, even though yet another set of skills will need to be mastered to control these screens, they may well be the wave of the future.

Click to view the article The fallacy of information overload
Wednesday, 23rd May 2012

A lot of the talk around social media in the last year has been around information overload. Social media has provided us with new and exciting ways to create content. But it has also meant learning new ways to manage and engage with social media tools. Are we teetering on the edge of an information overload precipice?


Click to view the article Information overload: fact, fantasy or filter failure?
Wednesday, 23rd May 2012

Information overload is a figment of your imagination. Or a failure of your filter. Or a symptom of your technological submissiveness. Depends on who you ask.

What if you had to sort through 3.5 million articles and social media posts a day and try to pull out the most relevant items for your organisation? What if you then had to cobble it all together into something readable for your top groups and executives in your organisation?
