    • In an optical touch display system, light from a primary source can be retroreflected to a detector in the absence of an object in the detection area. When an object is present, its position can be triangulated based on the direction of its shadows at the detectors. Accuracy can be improved with a secondary light source positioned off-axis from the primary light sources so that minimal light from the secondary source is retroreflected to the detectors. Instead, when an object is present, light from the secondary source may be reflected directly from the object. Each detector signal representing light due to the primary light source can be corrected to remove light reflected directly from the object based on identifying and removing a signal component representing light from the secondary light source. In some embodiments, this is facilitated by phasing the primary and secondary light sources.
    • 在光学触摸显示系统中,来自主要源的光可以在检测区域中没有物体的情况下被回射到检测器。 当物体存在时,其位置可以根据其在检测器处的​​阴影方向进行三角测量。 可以通过从主光源离轴定位的次级光源来改善精度,使得来自次级光源的最小光被回射到检测器。 相反,当存在物体时,来自次级源的光可以直接从物体反射。 可以基于识别和去除表示来自二次光源的光的信号分量来校正表示由于初级光源引起的光的每个检测器信号,以去除直接从物体反射的光。 在一些实施例中,通过对主光源和次光源进行定相来促进这一点。

    • A touch screen system that can approximate tracking and dragging states regardless of the user's orientation and without reliance on direct sensing of touch pressure or area. A first detector generates a signal representing a first image of an object interacting with the touch screen. A second detector generates a signal representing a second image of the object. A signal processor processes the first signal to determine approximated coordinates of a first pair of outer edges of the object and processes the second signal to determine approximated coordinates of a second pair of outer edges of the object. The signal processor then calculates an approximated touch area based on the approximated coordinates of the first pair of outer edges and the approximated coordinates of the second pair of outer edges of the object. If the approximated touch area is less than or equal to a threshold touch area, the signal processor determines that the object interacting with the touch screen indicates a tracking state. If the approximated touch area is greater than the threshold touch area, the signal processor determines that the object interacting with the touch screen indicates a selection state. The threshold touch area may be established by calibrating the touch screen system when the object interacting with the touch screen is known to indicate the tracking state.
    • 触摸屏系统可以跟踪和拖动状态,无论用户的方向如何,而不依赖于直接感测触摸压力或区域。 第一检测器产生表示与触摸屏交互的对象的第一图像的信号。 第二检测器产生表示对象的第二图像的信号。 信号处理器处理第一信号以确定对象的第一对外边缘的近似坐标,并处理第二信号以确定对象的第二对外边缘的近似坐标。 然后,信号处理器基于第一对外边缘的近似坐标和物体的第二对外边缘的近似坐标来计算近似触摸区域。 如果近似触摸区域小于或等于阈值触摸区域,则信号处理器确定与触摸屏交互的对象指示跟踪状态。 如果近似触摸区域大于阈值触摸区域,则信号处理器确定与触摸屏交互的对象指示选择状态。 阈值触摸区域可以通过当知道与触摸屏交互的对象来指示跟踪状态时校准触摸屏系统来建立。

    • A touch panel that has a front surface, a rear surface, a plurality of edges and an interior volume. An energy source is positioned in proximity to a first edge of the touch panel and is configured to emit energy that is propagated within the interior volume of the touch panel. A diffusing reflector is positioned in proximity to the front surface of the touch panel for diffusively reflecting at least a portion of the energy that escapes from the interior volume. At least one detector is positioned in proximity to the first edge of the touch panel and is configured to detect intensity levels of the energy that is diffusively reflected across the front surface of the touch panel. Preferably, two detectors are spaced apart from each other in proximity to the first edge of the touch panel, to allow calculation of touch locations using simple triangulation techniques.

    • Emitters and detectors are positioned in proximity to a display screen. Emitters emit energy beams that are diverged across the surface of the display screen. Emitters may be activated/deactivated in sequence, rapid enough to substantially ensure that several energy beams are interrupted by a touch of the display screen. Detectors receive energy beams over a range of angles and generate detection signals upon detecting energy beams. Detection maps are generated based on detection signals. Detection maps indicate which detector should receive an energy beam from which emitter at any point in time. Detections maps are compared to determine that energy beams have been interrupted by a touch. Based on the interrupted energy beams, the location of the touch on the display screen may be determined. The invention serves to reduce the number of emitters and detectors required in a touch panel display system and/or increase the sensitivity and accuracy thereof.
    • 发射器和检测器位于显示屏附近。 发射器发射跨越显示屏表面发散的能量束。 发射器可以被顺序地激活/去激活,足够快以基本上确保几个能量束被显示屏幕的触摸中断。 检测器在角度范围内接收能量束,并在检测能量束时产生检测信号。 基于检测信号生成检测图。 检测图表明哪个检测器应该在任何时间点接收发射器的能量束。 比较检测图以确定能量束已被触摸中断。 基于中断的能量束,可以确定显示屏上的触摸位置。 本发明用于减少触摸面板显示系统中所需的发射器和检测器的数量和/或提高其灵敏度和精度。
