    • A method for determining an intensity value of an interaction with a computer program is described. The method and device includes capturing an image of a capture zone, identifying an input object in the image, identifying an initial value of a parameter of the input object, capturing a second image of the capture zone, and identifying a second value of the parameter of the input object. The parameter identifies one or more of a shape, color, or brightness of the input object and is affected by human manipulation of the input object. The extent of change in the parameter is calculated, which is the difference between the second value and the first value. An activity input is provided to the computer program, the activity input including an intensity value representing the extent of change of the parameter. A method for detecting an intensity value from sound generating input objects, and a computer video game are also described. A game controller having LEDs, sound capture and generation, or an accelerometer is also described.

    • A hand-manipulated prop is picked-up via a single video camera, and the camera image is analyzed to isolate the part of the image pertaining to the object for mapping the position and orientation of the object into a three-dimensional space, wherein the three-dimensional description of the object is stored in memory and used for controlling action in a game program, such as rendering of a corresponding virtual object in a scene of a video display. Algorithms for deriving the three-dimensional descriptions for various props employ geometry processing, including area statistics, edge detection and/or color transition localization, to find the position and orientation of the prop from two-dimensional pixel data. Criteria are proposed for the selection of colors of stripes on the props which maximize separation in the two-dimensional chrominance color space, so that instead of detecting absolute colors, significant color transitions are detected. Thus, the need for calibration of the system dependent on lighting conditions which tend to affect apparent colors can be avoided.
    • 通过单个摄像机拾取手动操纵的支架,并且分析摄像机图像以隔离与对象相关的图像的部分,以将对象的位置和取向映射到三维空间中,其中, 对象的三维描述被存储在存储器中并且用于控制游戏程序中的动作,诸如在视频显示的场景中渲染相应的虚拟对象。 用于导出各种道具的三维描述的算法使用几何处理,包括区域统计,边缘检测和/或颜色转换定位,以从二维像素数据找到支柱的位置和方位。 提出了用于选择在二维色度空间中最大化分离的道具上的条纹颜色的标准,因此,不是检测绝对颜色,而是检测到显着的颜色转变。 因此,可以避免对依赖于影响表观颜色的照明条件的系统的校准的需要。
