Embodiment Construction

[0056] In the drawings, the same elements or elements having the same function are given the same reference numerals. figure 2 , 3 and 4 show the same frame of reference with a Cartesian coordinate system and vertical axes x, y and z.

[0057] Figures 1A to 1D An optical measuring device is shown, in the form of a spectacle device 1 or an eye-tracking device, respectively. The eyeglass device 1 is designed so that a person can wear it on his head, like a usual pair of eyeglasses. It comprises a frame 4 with two side bars 51 and 5r which support the spectacle device 1 on the ears of the person wearing it. In addition, the eyeglass device 1 is held in place on the head by the nose pad 7 . The main frame has a specific width w1 and height h. Its length l depends on the lengths of the side bars 5l and 5r. as in Figure 1C As seen in , the side bars 5l and 5r are hinged to the front of the frame 4 so that the distance w2 between the side bars 5l and 5r can be enlarged or s...

Abstract

The invention relates to an optical measuring device (1) for capturing at least one parameter of at least one eye (10l, 10r) of a test person (31) wearing the optical measuring device (1), comprising a frame (4), at least one frame insert (8l, 8r) attached to the frame (4) and at least one capturing unit (3l, 3r), wherein the frame (4) is designed to fix the optical measuring device (1) in such a way to the head of the test person (31), that the at least one frame insert (8l, 8r) is positioned in front of at least one eye (10l, 10r) of the test person (31) for at least one direction of view of the at least one eye (10l, 10r) on the optical axis (K) of the at least one eye (10l, 10r), and the capturing unit (3l, 3r) is designed to optically capture the at least one parameter of the at least one eye (10l, 10r), wherein the capturing unit (3l, 3r) is arranged in such a way (a) that the optical path (M) for the capturing of the at least one parameter of the at least one eye (10l, 10r) excludes the frame insert (8l, 8r).

Description

technical field [0001] The present invention relates to an optical measurement device for capturing at least one parameter of at least one eye of a test person wearing the optical measurement device, said optical measurement device comprising a frame, at least one frame insert connected to the frame, and at least a capture unit, wherein the frame is designed to fix the optical measuring device to the tester's head such that at least one frame insert is for at least one viewing direction of at least one eye on the optical axis of the at least one eye Located in front of at least one eye of the test person, the capture unit is designed to optically capture at least one parameter of the at least one eye. The invention also relates to a system comprising such an optical measuring device. Background technique [0002] The use of head-mounted eye-tracking devices is known from the prior art. US RE39,539E discloses a device for monitoring eye movements of a person. The system in...
