An Apple patent application published today shows that the Force Touch trackpad used in the 12-inch MacBook and latest 13-inch MacBook Pro could get more sophisticated in future versions. The patent describes how a mix of vibration and temperature could fool your finger into ‘feeling’ different surfaces, such as metal and wood.
For example, a glass surface may be controlled to have the temperature of a relatively cooler metal material and/or a relatively warmer wood material […]
In some cases, the temperature may be varied over time, such as in response to one or more touches detected using one or more touch sensors. For example, a metal material may increase in temperature while touched in response to heat from a user’s finger.
The patent describes how vibrations could be used to simulate a textured surface, such as the grain of a wooden surface … expand full story
