In embodiments of display viewing detection, a presence module, implemented on an electronic device, enables a first sensor to detect an object responsive to detecting audio via one or more microphones of the electronic device. The first sensor generates data that is used by the presence module to determine that the object is within a viewing range of the electronic device and that movement of the object is below a predetermined threshold. The presence module then enables at least a second sensor to confirm the object is viewing a display of the electronic device. When the object is detected by the second sensor, the presence module enables the display for viewing by the object.

An image display device acquires data representing a status of a temperature distribution of a machining machine based on information on machining and generates a temperature distribution image from the acquired data. Further, a three-dimensional machining simulation representing a status of machining is performed to generate a three-dimensional simulation animation and a projection image is generated from the three-dimensional simulation animation. Then, an image obtained by synthesizing the temperature distribution image and the projection image is generated and displayed.
