Haptic effect generation for space-dependent content

A method of authoring haptic effects, the method comprising:

• receiving a haptic track and a video texture map, the haptic track having haptic data, the haptic data defining operation of a haptic actuator, the video texture map representative of at least one frame of a video, the haptic track associated with the at least one frame of the video, and the video texture map having a plurality of video pixels;
• and
• generating haptic data modifiers associated with haptic pixels, each haptic pixel associated with at least one of the video pixels, the haptic data modifiers for modifying at least a portion of the haptic data and modifying operation of the haptic actuator.
