PSEUDO HAPTIC SENSE PRESENTATION APPARATUS, PSEUDO HAPTIC SENSE PRESENTATION METHOD, AND PROGRAM

1 . A pseudo haptic sense presentation apparatus comprising:

a visual object update processing circuitry that visually changes a visual object by a magnitude of visual change of the visual object according to a manipulation based on a motion of a body part on the basis of manipulation information indicating the manipulation and information indicating a relationship between the magnitude of visual change and a manipulation amount based on the manipulation; and

an output processing circuitry that outputs information for presenting the visually changed visual object,

wherein the relationship is defined at least according to a degree of a pseudo haptic sense to be presented.

2 . The pseudo haptic sense presentation apparatus according to claim 1 , wherein

the magnitude of visual change of the visual object corresponds to a magnitude of change of at least one of a size, a shape, a luminance, a color, or a pattern of the visual object, and

the visual object update processing circuitry changes at least one of a size, a shape, a luminance, a color, or a pattern of the visual object.

3 . The pseudo haptic sense presentation apparatus according to claim 1 , wherein

the relationship is a ratio of a change in the magnitude of change to a change in the manipulation amount,

the ratio in a case where an index representing the degree of the pseudo haptic sense is a first index value is a first value, and

the ratio in a case where the index is a second index value different from the first index value is a second value different from the first value.

4 . The pseudo haptic sense presentation apparatus according to claim 3 , wherein

a degree of the pseudo haptic sense represented by the first index value is greater than a degree of the pseudo haptic sense represented by the second index value, and

the first value is smaller than the second value.

5 . The pseudo haptic sense presentation apparatus according to claim 3 , wherein

the manipulation amount changes from a first manipulation amount to a second manipulation amount and/or the manipulation amount changes from the second manipulation amount to the first manipulation amount according to the manipulation,

the first manipulation amount is different from the second manipulation amount,

the ratio when the manipulation amount is the first manipulation amount is a third value, and

the ratio when the manipulation amount is the second manipulation amount is a fourth value different from the third value.

6 . The pseudo haptic sense presentation apparatus according to claim 5 , wherein

the first manipulation amount is greater than the second manipulation amount, and

the third value is smaller than the fourth value, or the third value is greater than the fourth value.

7 . A pseudo haptic sense presentation method comprising:

a visual object update step of visually changing a visual object by a magnitude of visual change of the visual object according to a manipulation based on a motion of a body part on the basis of manipulation information indicating the manipulation and information indicating a relationship between the magnitude of visual change and a manipulation amount based on the manipulation; and

an output step of outputting information for presenting the visually changed visual object,

wherein the relationship is defined at least according to a degree of a pseudo haptic sense to be presented.

8 . A non-transitory computer-readable recording medium storing a program for causing a computer to function as the pseudo haptic sense presentation apparatus according to claim 1 .
