| description | To provide a visual perception load estimation device and a visual perception load estimation program capable of improving accuracy in estimating a driver's visual perception load in consideration of a state of a visual object.SOLUTION: A visual perception load estimation device includes: an acquisition unit for acquiring state information indicating a state of a user visually recognizing a visual object and visual object information on the visual object; a sight line deviation estimation unit for estimating sight line deviation frequency, which is the frequency of the visual object being deviated from a visual field which is set in a range determined beforehand from the sight line of the user visually recognizing the visual object using the acquired state information; a visual acuity estimation unit for estimating dynamic visual acuity indicating the visual acuity for visually recognizing the dynamically changing visual object using the sight line deviation frequency, and estimating target visual acuity indicating visual acuity necessary for visually recognizing the visual object using the visual object information; and a visual perception load estimation unit for estimating a visual perception load indicating a load for visually recognizing the visual object using the dynamic visual acuity and the target visual acuity.SELECTED DRAWING: Figure 2
【課題】視対象の状態を考慮して、運転者の視覚負担を推定する精度を向上させることができる視覚負担推定装置、及び視覚負担推定プログラムを提供することを目的とする。【解決手段】視覚負担推定装置は、視対象を視認するユーザの状況を示す状況情報、及び視対象に関する視対象情報を取得する取得部と、取得した状況情報を用いて、視対象を視認するユーザの視線から予め定められた範囲に設定された視野であって、視野から視対象が外れた頻度である視線ブレ頻度を推定する視線ブレ推定部と、視線ブレ頻度を用いて、動的に変化する視対象を視認するための視力を示す動的視力を推定し、視対象情報を用いて、視対象を視認するために必要な視力を示す視標視力を推定する視力推定部と、動的視力、及び視標視力を用いて、視対象を視認する負担を示す視覚負担を推定する視覚負担推定部と、を備えている。【選択図】図２ |
