PROBLEM TO BE SOLVED: To provide a technology for generating and presenting heartbeat feeling information by acquiring heartbeat feeling intensity only from a pulsation interval.SOLUTION: The interval of pulsation of the heart of an animal which can be acquired by a biological sensor is defined as a pulsation interval, a sensation that the animal feels about the pulsation of its own heart is defined as a heartbeat sensation, the intensity of the heartbeat sensation is defined as heartbeat feeling intensity, and information for presenting the heartbeat sensation is defined as heartbeat feeling information. A heartbeat feeling information generation device includes a heartbeat feeling intensity estimation part for estimating heartbeat feeling intensity such that an estimation value of heartbeat feeling intensity corresponding to a section in which a statistical value of the pulsation interval is a first value is larger than an estimation value of heartbeat feeling intensity corresponding to a section in which a statistical value of a pulsation interval is a second value larger that the first value by using a sequence of pulsation intervals, and a heartbeat feeling information synthesis part for synthesizing heartbeat feeling information from the pulsation interval and the estimation value of the heartbeat feeling intensity. The heartbeat feeling information is information for presenting a heartbeat sensation repeating at pulsation intervals and is information for presenting a heartbeat sensation of strength corresponding to the estimation value of the heartbeat feeling intensity.【課題】拍動間隔のみから鼓動感強度を求め、鼓動感情報を生成、呈示する技術を提供する。【解決手段】生体センサで取得できる動物の心臓の拍動の間隔を拍動間隔とし、動物が自身の心臓の拍動に対して感じる感覚を鼓動感覚とし、鼓動感覚の強さを鼓動感強度とし、鼓動感覚を呈示するための情報を鼓動感情報とし、鼓動感情報生成装置は、拍動間隔の系列を用いて、拍動間隔の統計値が第１値である区間に対応する鼓動感強度の推定値が、拍動間隔の統計値が第1値よりも大きい第２値である区間に対応する鼓動感強度の推定値よりも大きくなるように、鼓動感強度を推定する鼓動感強度推定部と、拍動間隔と鼓動感強度の推定値とから鼓動感情報を合成する鼓動感情報合成部とを含む。鼓動感情報は、拍動間隔で繰り返される鼓動感覚を呈示するための情報であって、鼓動感強度の推定値に対応する強さの鼓動感覚を呈示するための情報である。【選択図】図１
