Embodiment Construction

[0015] One embodiment is a system that transforms or "morphs" haptic signals designed for high-definition haptic output devices, such as linear resonant actuators or piezoelectric actuators, into A special type of haptic signal aggregated by a vibrotactile haptic effect pattern (or some other type of haptic effect pattern) of a haptic output device such as an eccentric rotating mass motor. In transforming or "warping" the haptic signal, the system replaces the haptic effect pattern contained within the haptic signal with a vibrotactile haptic effect pattern. A haptic effect schema is a collection of data that causes a haptic output device to produce haptic effects. A vibrotactile haptic effect mode (also identified as a "vibrate mode") is a specific type of haptic effect mode that causes an SD haptic output device to produce a vibrotactile haptic effect for a specified duration and to stop producing a vibrotactile haptic effect for a specified duration. duration. The haptic ...

Abstract

A system is provided that transforms haptic signals into vibrotactile haptic effect patterns. The system receives a haptic signal that includes haptic effect patterns. The system further detects a start time and an end time for each haptic effect pattern. The system further detects haptic effect patterns based on a characteristic, and replaces the detected haptic effect patterns with substitute haptic effect patterns. The system further shifts the start time for each haptic effect pattern back by a shift duration. The system further assigns a vibrotactile haptic effect pattern to each haptic effect pattern. The system further sends the vibrotactile haptic effect patterns to a standard-definition haptic output device to generate vibrotactile haptic effects.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application Serial No. 61 / 874,920, filed September 6, 2013 (the disclosure of which is incorporated herein by reference), and also claims U.S. Provisional Patent Application Serial No. 61 / Priority of 906,975 (the disclosure of which is incorporated herein by reference). technical field [0003] Embodiments relate generally to a device, and more particularly to devices that produce haptic effects. Background technique [0004] Haptics is a tactile and force feedback technology that exploits a user's sense of touch by applying tactile feedback effects (ie, "haptic effects") to the user, such as force, vibration, and motion. Devices such as mobile devices, touch screen devices, and personal computers can be configured to generate (generate) haptic effects. Generally, calls to embedded hardware capable of producing haptic effects, such as actuators, can be prog...
