VISUAL FIELD-CALCULATING UNIT AND VISUAL FIELD-CALCULATING METHOD |
摘要 |
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 (130) includes a saccade detection unit (131) 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 calculation unit (132) 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 calculation unit (133) that extracts a saccade whose speed exceeds a first threshold, calculates a displacement vector of the extracted saccade, and calculates an area including a final point of the displacement vector as the visual field range of the user. |
