    • A device (40) for imparting distance information to a human subject, comprising a hand-holdable housing (42) having a front end (44) and an axis (46), configured so when said housing (42) is held in a human hand with said front end (44) forwards, said axis (46) points straight ahead; physically associated with said housing (42), a light-source (24) configured for projecting a beam of light through a light- source aperture (28) in a direction not more than 4° divergent from parallel to said axis (46); physically associated with said housing (42), a light - detector (26) configured to detect light projected by said light-source (24), reflected from a reflecting object located at a distance from said front end (44) between a minimum distance and a maximum distance and entering through a light - detector aperture (30), at a frame rate where a detection location of said light reflected from a reflecting object on an epipolar line of said light - detector (26) is dependent on said distance to the reflecting object; and functionally associated with said light - detector (26), a distance reporter (56, 68) configured to produce a signal perceptible to a human subject, said perceptible signal modulated as a function of said detection location at a reporting rate; wherein said light-source aperture (28) and said light - detector aperture (30) are separated by an inter- aperture separation of not more than about 5 cm, wherein along said epipolar line between said detection location of light reflected from a reflecting object at said minimum distance and said detection location of light reflected from a reflecting object at said maximum distance there are at least about 20 distinct detection locations, and wherein said perceptible signal is modulated differently for each of said at least about 20 distinct detection locations.
    • 一种用于向人类对象传递距离信息的装置(40),包括具有前端(44)和轴线(46)的手持式外壳(42),当所述外壳(42)保持在人体 所述前端(44)向前移动,所述轴线(46)向前指向; 物理地与所述壳体(42)相关联的光源(24),被配置为将光束通过光源孔径(28)以不大于平行于所述轴线(46)的4°的方向投射; 物理地与所述壳体(42)相关联的光检测器(26),被配置为检测由所述光源(24)投射的光,从位于距所述前端(44)一定距离的反射物体反射的光的最小距离 和最大距离,并且以从所述光检测器(26)的核线上的反射物体反射的所述光的检测位置取决于所述光检测器孔径(30)的所述距离 反射物体 并且与所述光检测器(26)功能相关联,距离报告器(56,68)被配置为产生对人类受检者可感知的信号,所述可感知信号以报告速率作为所述检测位置的函数进行调制; 其中所述光源孔径(28)和所述光检测器孔径(30)由不大于约5cm的孔径间隔分开,其中沿所述核极线在所述从反射物体反射的光的检测位置之间 在所述最小距离处,并且在所述最大距离处从反射物体反射的光的所述检测位置具有至少约20个不同的检测位置,并且其中对于所述至少约20个不同检测位置中的每一个,所述可感知信号被不同地调制。
