摘要： A touch panel device includes processing circuitry to generate coordinate information based on a signal outputted from the touch panel and to output a detection value based on depressing force. The processing circuitry previously stores a plurality of pieces of predictive detection value information, selects a piece of predictive detection value information based on a gradient of the detection value, obtains a final predictive detection value that the predictive detection value finally reaches by using the selected predictive detection value information, obtains a present predictive detection value by using the selected predictive detection value information, and executes a correction process of reducing influence of a memory effect by bringing a present detection value close to the final predictive detection value when an absolute value of a difference between the present predictive detection value and the present detection value is less than or equal to a predetermined threshold value.

摘要： A touch panel device includes processing circuitry to generate coordinate information indicating a position of a touch operation; to generate a pressing value corresponding to pressing force applied to an operation surface of a touch panel; to classify the positions of touch operations included in operation logs each being data including the coordinate information and information indicating the pressing value into groups and to determine group regions respectively corresponding to the groups; to determine a threshold value of the pressing value in each of the group regions based on the operation logs; and to judge that the touch operation is a depressing operation with pressing force if the pressing value is greater than or equal to the threshold value and to judge that the touch operation is a normal touch operation other than the depressing operation if the pressing value is less than the threshold value.

摘要： A position detection device includes processing circuitry: to receive an image captured by a monitoring camera, to execute a process for detecting a person in the image, and to output two-dimensional camera coordinates indicating a position of the detected person; to transform the two-dimensional camera coordinates to three-dimensional coordinates; to recognize a character string on a nameplate of a device in a wearable camera image captured by a wearable camera; to search a layout chart of the device for the recognized character string; to determine two-dimensional map coordinates based on a position where the character string is found when the recognized character string is found in the layout chart, and to calculate the two-dimensional map coordinates based on the three-dimensional coordinates when the recognized character string is not found in the layout chart; and to output image data in which position information is superimposed on a map.
