Publication number: 20160139674Abstract: An information processing device includes a storage and an circuit. The storage stores first distance information indicating a distance between a reference point and a first surface and first shape information indicating a surface shape of the first surface. The circuit acquires second distance information indicating distance between the reference point and an object. The circuit determines if an operation inputted by user is present or absent by using the second distance information. The circuit determines whether a first condition is satisfied or not by comparing the first shape information with second shape information. The circuit updates the first distance information based on the second distance information when the operation is determined to be absent and the first condition is determined to be satisfied.Type: ApplicationFiled: October 22, 2015Publication date: May 19, 2016Inventors: Wataru WATANABE, Yuma SANO, Ryosuke NONAKA, Masahiro BABA
