Abstract
A technique is provided to present more intuitive settings of a haptic sensation. In particular, a signal generation device is provided that includes an input unit to accept setting information including information indicative of the direction of the haptic sensation to be presented by a target object; and a generation unit that generates a waveform signal for presenting the haptic sensation based on the setting information accepted by the input unit.
Claims19
A signal generation device comprising:
- an input unit configured to accept setting information that includes first information indicative of a first direction and a second direction of a haptic sensation to be presented by a target object, and second information indicative of an intensity of the haptic sensation to be presented by the target object, the first direction, the second direction and the intensity being associated with a time on a timeline of the haptic sensation to be presented by the target object;
- a generation unit configured to generate a waveform signal to generate the haptic sensation based on the setting information accepted by the input unit;
- an image generating unit configured to generate an image including a waveform with a time axis representing the timeline, the waveform indicating the first information and the second information of the haptic sensation at each time on the timeline, the first direction and the second direction being indicated by a first side of the time axis and a second side of the time axis that is opposite to the first side;
- and
- an operation unit configured to edit the waveform in the image to change the setting information.

A signal generation method comprising:
- accepting, by at least one processor, setting information that includes first information indicative of a first direction and a second direction of a haptic sensation to be presented by a target object, and second information indictive of an intensity of the haptic sensation to be presented by the target object, the first direction, the second direction and the intensity being associated with a time on a timeline of the haptic sensation to be presented by the target object;
- generating, by the at least one processor, a waveform signal to present the haptic sensation based on the setting information that is accepted;
- generating, by the at least one processor, an image including a waveform with a time axis representing the timeline, the waveform indicating the first information and the second information of the haptic sensation at each time on the timeline, the first direction and the second direction being indicated by a first side of the time axis and a second side of the time axis that is opposite to the first side;
- and
- editing, by the at least one processor, the waveform in the image to change the setting information.

A signal generation system comprising:
- memory that stores software code for a signal generation program;
- and
- at least one processor that, when executing the software code for the signal generation program, configures a computer to provide:
- an input unit configured to accept setting information that includes first information indicative of a first direction and a second direction of a haptic sensation to be presented by a target object, and second information indicative of an intensity of the haptic sensation to be presented by the target object, the first direction, the second direction and the intensity being associated with a time on a timeline of the haptic sensation to be presented by the target object;
- a generation unit configured to generate a waveform signal to present the haptic sensation based on the setting information accepted by the input unit;
- an image generating unit configured to generate an image including a waveform with a time axis representing the timeline, the waveform indicating the first information and the second information of the haptic sensation at each time on the timeline, the first direction and the second direction being indicated by a first side of the time axis and a second side of the time axis that is opposite to the first side;
- and
- an operation unit configured to edit the waveform in the image to change the setting information.
