Abstract
A method of creating a haptic effect on a touch surface, the method including the steps of detecting a location of a first appendage and a second appendage on a touch surface, applying a mechanical force to the first and second appendages at the detected locations on the touch surface, modulating the amplitude of the mechanical force to adjust a friction force applied to the first appendage and second appendage to simulate a texture.

A method of creating a haptic effect on a touch surface, the method including the steps of:
- detecting a location of a first appendage and a second appendage on a touch surface;
- applying a mechanical force to the first and second appendages at the detected locations on the touch surface;
- modulating the amplitude of the mechanical force to adjust a friction force applied to the first appendage and second appendage to simulate a texture.
The method of clam 1 wherein the mechanical force is modulated based on the position of the first appendage relative to the second appendage.
A haptic device including:
- a position detection unit that detects a location of a first appendage and a second appendage on a touch surface;
- a mechanical force generation unit that applies a mechanical force on the first appendage and second appendage at the detected locations on the touch surface,
- wherein the mechanical force unit modulates the amplitude of the mechanical force to adjust a friction force applied to the first appendage and second appendage to simulate a texture.
The device of clam 11 wherein the mechanical force is modulated based on the position of the first appendage relative to the second appendage.
