Apple's Taptic Engine is the unsung hero of the new iPhone 6s upgrade. A lot less "sexy" than 3D Touch, it is nonetheless likely to be a feature that you will grow to love just as much over time. Like many smartphones, Apple's iPhones in the past have used a vibrating motor, either with a rotational motor or a linear oscillating motor, for vibration effects when your iPhone is set to vibrate for calls and/or messages. The new Taptic Engine in the iPhone 6s is much more sophisticated than any vibrating motor Apple has used in an iPhone before. Not only is it an integral component of the 3D Touch experience, it provides a much more refined and capable vibration effect than ever before.
A phone has been modified to be able to transfer a squeeze to another phone. A prototype by Nokia Research and the Helsinki Institute of Information Technology amended an N900 to use a resistor to detect up to four different levels of pressure from compression. The recipient of the phone call receives different levels of vibration, depending on the amount of pressure applied.
Researchers have found a way to increase the resolution of a display beyond its normal capabilities, thanks to the inherent latency of the brain's visual processing. Floraine Berthouzoz and Raqanan Fattal, graphics researchers, found that by vibrating the screen and quickly showing four lower-resolution images of a larger-resolution photograph, the viewer's brain can combine the images and see something close to the original photo.
In an effort to make typing on the iPhone more familiar, the University of Glasgow has unveiled a hack that provides vibration feedback when a virtual key is pressed, simulating the effect of typing on a real keyboard. The patch enables what the University calls haptic feedback, which researchers say can help improve typing speeds, while simultaneously reducing errors. The hack is available from the University's Google Code page, requiring a jailbroken 1.1.3 iPhone.
