Patent number: 8384666Abstract: An input device having a manipulation member is disclosed. The input device has an absolute input mode and a relative input. In the absolute input mode, the input device determines a coordinate of a pointed point on a window of a display unit based on a coordinate of the manipulation member. In the relative input mode, the input device determines the pointed point on the window in a relative manner based on a two-dimensional displacement of the manipulation member with respect to a reference position, which is set when an input mode is switched into the relative input mode. When the manipulation member receives a load that causes the manipulation member to move beyond a predetermined range, the input device generates and applies a force corresponding to the load to the manipulation member.Type: GrantFiled: May 14, 2009Date of Patent: February 26, 2013Assignee: DENSO CORPORATIONInventors: Masahiro Itoh, Nozomi Kitagawa, Shigeaki Nishihashi, Takeshi Yamamoto, Takeshi Haruyama

Patent number: 8355838Abstract: An indication unit indicates arranged selective areas on a display surface for accepting input. A move unit moves an instructed position on the display surface according to an operation quantity of an operation unit. A selected-state determination unit determines a selected-state area from the selective areas according to the instructed position. A width determination unit determines a width of the selected-state area in each of an x-axis direction and a y-axis direction of the display surface. A moving speed set unit sets a moving speed of the instructed position variably at least when the instructed position passes through the selected-state area such that: a velocity component in the x-axis direction becomes larger as the determined width in the x-axis direction becomes larger, and a velocity component in the y-axis direction becomes larger as the determined width in the y-axis direction becomes larger.Type: GrantFiled: December 15, 2010Date of Patent: January 15, 2013Assignee: DENSO CORPORATIONInventors: Masahiro Itoh, Takeshi Haruyama
