Patent number: 11829532Abstract: There is provided a control device including a control unit that controls tactile sense presentation for presenting a stimulation through a tactile sense and hearing sense presentation for presenting a stimulation through a hearing sense, when it is determined that an operation has been performed on an input unit including a contact area with which an object is brought into contact. The control unit controls displacement indicating a difference from a reference position of the contact area, the displacement being related to the tactile sense presentation, and a strength of sound related to the hearing sense presentation, so that at least one of the tactile sense presentation and the hearing sense presentation is in a proper range that is a range allowing a user of the input unit to perceive the presentation and not causing the user to have unpleasant feeling.Type: GrantFiled: April 17, 2020Date of Patent: November 28, 2023Assignee: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Takeshi Ohnishi, Fumiaki Hirose, Yuma Nakai
