Summary:To cause the sensitivity of a pointer to be reduced without requiring a user to perform any operation separately, when the user is pointing or likely to point to a specific position in a virtual three-dimensional space by a pointer that virtually emits a ray to the virtual three-dimensional space.SOLUTION: An image processing unit 26 perspectively projects a virtual three-dimensional space where a virtual object is located, on the basis of a visual line direction 42 that is set in the virtual three-dimensional space in accordance with the attitude of an information processing device 10 to generate a two-dimensional image and causes it to be displayed on a display 14. A ray control unit 28 sets a ray emission angle in the virtual three-dimensional space on the basis of the attitude of a pointer 12. When a sensitivity reduction condition is satisfied that the angle change amount of the visual line direction 42 in a prescribed time is less than or equal to a threshold visual line angle and the angle change amount of a ray emission angle in the prescribed time is less than or equal to a threshold emission angle, the ray control unit 28 reduces the sensitivity of the pointer 12, as compared with the case where the sensitivity reduction condition is not satisfied.SELECTED DRAWING: Figure 5 【課題】仮想３次元空間に仮想的にレイを出射するポインタによって、ユーザが仮想３次元空間の特定の位置を指し示している場合又は指し示そうとしている場合に、ユーザが別途の操作を行う必要なくポインタの感度を低下させる。【解決手段】画像処理部２６は、情報処理装置１０の姿勢に応じて仮想３次元空間に設定された視線方向４２に基づいて、仮想オブジェクトが配置された仮想３次元空間を透視投影して２次元画像を生成しディスプレイ１４に表示させる。レイ制御部２８は、ポインタ１２の姿勢に基づいて仮想３次元空間におけるレイの出射角度を設定する。レイ制御部２８は、所定時間内における視線方向４２の角度変化量が閾値視線角度以下であり、且つ、所定時間内におけるレイの出射角度の角度変化量が閾値出射角度以下であるという感度低下条件を満たす場合に、当該感度低下条件を満たさない場合に比して、ポインタ１２の感度を低減させる。【選択図】図５
