US 10,096,213 B2 · Signal for carrying washout request in haptic audiovisual content, related method and device

Abstract

A method, a device and a signal enabling automatic washouts in HAV contents. Washout related information is added to a signal representing a HAV content so that a HAV rendering device may adapt the washout to its physical limitations defined by the device capabilities as well as the user preferences. Different types of washouts are proposed. The HAV content signal comprises a first information representative of a haptic washout effect and an optional second information representative of the parameters required for the haptic washout effect. The method comprises performing a first haptic effect, computing the haptic washout effect according to device capabilities, user preferences, type of washout obtained from washout flags and optional washout parameters, and performing the haptic washout effect.

Dependent claims

A method for controlling rendering of a haptic effect, the method being implemented in a haptic rendering device and comprising:

obtaining a signal comprising information representative of the haptic effect to be rendered, the information carrying at least a first information whose value is representative of a haptic washout effect to be performed after the haptic effect, said haptic washout effect being in opposition with the haptic effect;
providing a first haptic command representative of the haptic effect to a haptic actuator to perform the haptic effect;
computing a second haptic command representative of the haptic washout effect, the second haptic command being adapted to a haptic rendering according to device capabilities;
and
providing the second haptic command to the haptic actuator to perform the haptic washout effect.

A data processing apparatus for controlling the rendering of a haptic effect, comprising:

an input interface configured to obtain a signal comprising information whose value is representative of an haptic effect to be rendered characterized in that the signal carries at least a first information representative of a haptic washout effect to be performed after the haptic effect, said haptic washout effect being in opposition with the haptic effect;
a haptic interface configured to:
provide a first haptic command representative of the haptic effect to a haptic actuator to perform the haptic effect;
obtain device capabilities from the haptic actuator;
compute a second haptic command representative of the haptic washout effect, the second haptic command being adapted to a haptic rendering according to device capabilities;
and
provide the second haptic command to the haptic actuator to perform the haptic washout effect a memory configured to provide at least the haptic user preferences;
and
a processor configured to compute the haptic washout effect, according to at least one of the device capabilities and user preferences.
