摘要： A component in a horizontal direction (the x-axis component) of a movement amount first acquired after a pointing device is reset and a component in a vertical direction (the y-axis component) are compared, a movement input is regarded as provided only in the horizontal direction in case the absolute value of the x-axis component is larger than the absolute value of the y-axis component, a movement input is regarded as provided only in the vertical direction in case the absolute value of the y-axis component is larger than the absolute value of the x-axis component, a movement input is regarded as provided in the same direction unless the ratio of components of movement inputs is greatly changed subsequently, and continuous movement inputs in the same direction are facilitated.

摘要： In a display apparatus for presentation including an image display device 30 that allows for moving a selection marker across a plurality of menu items arranged in vertical and horizontal directions and displayed on a screen 1 in accordance with received angular velocity information, a menu item to which the selection marker should be moved is determined in accordance with the number of cycles of angular velocity sampling during which the move distance of the pointing device obtained for every sampling cycle from the angular velocity information exceeds a predetermined value continuously. This improved the inconvenience to use with a conventional pointing device in which a distance by which an object should be moved on the display screen is proportional to the entire distance over which the pointing device was moved, calculated from angular velocity; thus, the operator has to tilt the remote controller incorporating a gyroscope to a large extent to move the object by a long distance on the screen.
摘要翻译：在一种用于演示的显示装置中，包括图像显示装置30，其允许沿着垂直和水平方向排列的多个菜单项移动选择标记，并根据接收到的角速度信息显示在屏幕1上;菜单项，根据角速度采样的周期数，根据角速度信息获得的每个采样周期获得的指示装置的移动距离连续超过预定值，确定移动选择标记。这改善了使用常规指点设备的不方便性，其中在显示屏幕上物体应该移动的距离与从角速度计算的指示设备移动的整个距离成比例; 因此，操作者必须将包含陀螺仪的遥控器在很大程度上倾斜以在屏幕上长距离移动物体。
