The latter patent complements one already awarded earlier for the asymmetrical fans used in the RMBP to suppress fan noise, while the haptic feedback patent hints at future changes for iOS devices.

Roller design uses actuators to alter stylus tip resistance

Sony has recently filed a number of patents related to haptic feedback via friction, instead of the vibration method that most devices use. A "rolling contact ball gripping mechanism" on the end of a stylus uses actuators to increase or decrease the ball's resistance to rolling, making it easier or harder to move the stylus across a screen.

Electrostatic field generator offers multiple touch sensations

A team at Disney Research has created a new wearable tactile technology that effectively changes the sensation felt when touching physical objects, using electricity. Revel can add artificial tactile sensations to almost any surface or object, without having to use the motors and actuators currently employed by touchscreen haptic feedback found in phones and tablets, and force feedback rumbling found in game controllers.
