Patent number: 10474292Abstract: An information reception device is provided with: operation surface which is adjusted to produce a characteristic index vibration by an object contact; a storage device stores candidate information (candidate information is related with the index vibration) which serves as a candidate of input information; a microphone which acquires observation information according to observation of the actual vibration arising in the surrounding environment; and a CPU. The CPU (selecting part) judges whether or not the index vibration exists in the observation information acquired. When the CPU judges that the index vibration exists, the CPU selects the candidate information which is related with the index vibration as the input information.Type: GrantFiled: September 15, 2017Date of Patent: November 12, 2019Assignees: MEGACHIPS CORPORATION, NITTO DENKO CORPORATIONInventors: Motoyasu Tanaka, Takashi Matsutani, Masayasu Yamamoto, Yuki Haraguchi, Hideo Sugawara, Ikuo Kawamoto, Motoki Haishi, Nobuyuki Kozonoi
