    • A roll detection system is disclosed for detecting a roll angle of a light emitting apparatus around a longitudinal axis thereof. The light emitting apparatus preferably is a pointing device (2). The system furthermore comprises a light detecting arrangement (4) for detecting light emitted by the pointing device (2) and means for determining where the pointing device is pointed. The pointing device (2) comprises at least a first (X1) and a second light source (Y1). The first (X1) and second light source (Y1) emit light with a different polarization orientation. The light detecting arrangement (4) is equipped with a polarization filter (3). The orientation of the polarization of the light emitted by the first (X1) and second light source (Y1) differs by an angle unequal to 90°. With the system the roll angle of the pointing device (2) can be determined for a large angle range.
    • 公开了一种用于检测发光设备围绕其纵向轴线的侧倾角的侧倾检测系统。 发光装置优选是指向装置(2)。 该系统还包括用于检测由指示设备(2)发射的光的光检测装置(4)以及用于确定指示设备指向何处的装置。 指示设备(2)至少包括第一光源(X1)和第二光源(Y1)。 第一(X1)和第二光源(Y1)以不同的偏振取向发射光。 光检测装置(4)配备有偏振滤波器(3)。 由第一光源(X1)和第二光源(Y1)发射的光的偏振方向相差一个不等于90°的角度。 利用该系统,可以在大角度范围内确定指向装置(2)的侧倾角。

    • A system is disclosed comprising a pointing device (10), an appliance (20) and at least two light sources (30), which are either part of the appliance (20) or which are positioned in its vicinity. The pointing device (10) comprises a light detector (12) for detecting light signals from the at least two light sources (30). The system further comprises measuring means (14) for measuring a property of the detected light signals, representative of the aiming point of the pointing device (10). The system can be used for controlling a free moving cursor on the screen of the appliance (20). Alternatively, it can be used for controlling other appliances by movement or gesture of the pointing device
    • 公开了一种系统,其包括指示设备(10),设备(20)和至少两个光源(30),其是设备(20)的一部分或者位于其附近。 指示装置(10)包括用于检测来自至少两个光源(30)的光信号的光检测器(12)。 该系统还包括用于测量检测到的光信号的属性的测量装置(14),其代表指示装置(10)的瞄准点。 该系统可用于控制设备(20)的屏幕上的自由移动的光标。 或者,其可以用于通过指示设备的移动或姿态来控制其他设备
