SOFTNESS FEELING CONTROL DEVICE, SOFTNESS FEELING PRESENTATION SYSTEM, SOFTNESS FEELING CONTROL METHOD, AND PROGRAM
A softness impression control device receives designation information for designating a softness impression for a presented visual target, and obtains and outputs a deformation speed index corresponding to a softness impression index indicating a softness impression designated by the designation information using information representing a correspondence between a deformation speed index indicating a deformation speed of a visual target and a softness impression index indicating a softness impression given by the visual target deforming at the deformation speed. By presenting the presented visual target deforming at the deformation speed indicated by the output deformation speed index, it is possible to cause a designated softness impression to be given.
1 . A softness impression control device comprising processing circuitry configured to:
receive designation information for designating a softness impression for a presented visual target; and
use information indicating a correspondence between a deformation speed index indicating a deformation speed of a visual target and a softness impression index indicating a softness impression given by the visual target deforming at the deformation speed to obtain the deformation speed index corresponding to the softness impression index indicating a softness impression designated by the designation information.
2 . The softness impression control device according to claim 1 , wherein
a softness impression indicated by the softness impression index corresponding to the deformation speed index indicating a first deformation speed is greater than a softness impression indicated by the softness impression index corresponding to the deformation speed index indicating a second deformation speed lower than the first deformation speed.
3 . The softness impression control device according to claim 1 , wherein
the presented visual target includes a first presented visual target and a second presented visual target presented together with the first presented visual target,
the processing circuitry receives first designation information that is the designation information for designating a softness impression for the first presented visual target and second designation information that is the designation information for designating a softness impression for the second presented visual target, and
the processing circuitry obtains a first deformation speed index that is the deformation speed index corresponding to the softness impression index indicating the softness impression designated by the first designation information and a second deformation speed index that is the deformation speed index corresponding to the softness impression index indicating the softness impression designated by the second designation information.
4 . The softness impression control device according to claim 1 , wherein the processing circuitry is configured to further
obtain and output the presented visual target deforming at a deformation speed based on the deformation speed index and/or output a command for deforming the presented visual target at the deformation speed based on the deformation speed index.
5 . The softness impression control device according to claim 4 , wherein
a deformation speed based on the deformation speed index in a first time interval is different from a deformation speed based on the deformation speed index in a second time interval different from the first time interval indicated by the deformation speed index.
6 . A softness impression presentation system comprising the softness impression control device according to claim 4 , wherein
the softness impression control device outputs the command, and
the softness impression presentation system further comprises:
a presentation device configured to present the presented visual target deformed according to the command; and
an imaging device configured to image the presented visual target presented by the presentation device to obtain a video image of the presented visual target.
7 . A softness impression control method of a softness impression control device, the method comprising:
receiving designation information for designating a softness impression for a presented visual target; and
using information indicating a correspondence between a deformation speed index indicating a deformation speed of a visual target and a softness impression index indicating a softness impression given by the visual target deforming at the deformation speed to obtain the deformation speed index corresponding to the softness impression index indicating a softness impression designated by the designation information.
8 . A non-transitory computer-readable recording medium storing program for causing a computer to serve as the softness impression control device according to claim 1 .
