Abstract:
A display control apparatus includes: an input unit that receives state information indicating at least one of a state of a moving object, a state of inside of the moving object, and a state of outside of the moving object; and a controller that controls a displayer, which generates a predetermined image and outputs the predetermined image onto a display medium, based on the state information. The predetermined image shows a presentation image including text, when displayed on the display medium. The controller causes the displayer to generate a first predetermined image showing a first presentation image including first text corresponding to a predetermined event, determines whether the at least one state has made a predetermined change, based on the state information, and causes the displayer to generate a second predetermined image showing a second presentation image including second text corresponding to the predetermined event.
Abstract:
A visual field calculation apparatus capable of accurately calculating a visual field range of a user without using a complex configuration is provided. The visual field calculation apparatus includes a saccade detector that detects a saccade on the basis of a first gaze direction detected at a first timing and a second gaze direction detected at a second timing, a saccade speed calculator that calculates speed of the saccade on the basis of a time difference between the first timing and the second timing, the first gaze direction, and the second gaze direction, and a visual field range calculator that calculates a displacement vector of a saccade whose speed exceeds a first threshold, and calculates an area including a final point of the displacement vector as the visual field range of the user.
