Thanks to a front-acing 1.31 megapixel camera, the user of a Vaio E Series 14P can control basic features of the notebook and software via hand movements. However, it is a very careful and basic implementation as only Windows Media Player, Internet Explorer 9, PowerPoint and PowerDVD support gestures at this time.
On the hardware side, the 14P comes with n Intel Core i3-2350M (2.3GHz) that is combined with the HM76 chipset. There is 4GB DDR3 1333MHz memory, a 500GB HDD storage, AMD Radeon HD 7670M graphics and integrated Intel HD Graphics 3000 as well as a 14-inch display that delivers a resolution of 1366 x 768 pixel. The notebook is currently on sale in Europe.
Gesture control is an intriguing new way that could be an evolutionary step above a touchscreen and by far more useful on notebooks that touch or audio-input. However, gesture interfaces are currently way too crippled to make sense for most users beyond a nice-to-have feature. Gestures require, just like touch, a system-wide integration and they need plenty of app support to become an appealing feature.
I have always used "gestures" over the Keyboard and even over the mouse pad.
They work for me.
