Definitions
- the invention relates to a method for producing at least one nosepiece of eye-catching glasses according to claim 1.
- Glasses are stored, among other things, on the nose of a person wearing glasses.
- the glasses either lie directly on the nose by means of the frame, or the glasses contact the nose via so-called nose pads or via a saddle bridge.
- the position of the glasses, in particular the glasses, relative to the eyes of the glasses wearer is determined by the contact situation on the nose and the contact situation of the temples on the ears.
- optical eyeglass frames therefore offer frames or frames of different sizes or widths, with local retailers stocking the sizes that correspond to the common physiognomic features in the region. Different sized frames are no problem optically, since the lenses are individually cut and adapted to the respective frame.
- the glasses or the frame contain essential elements which are essential for the function of such glasses. This is the case, for example, with glasses which are designed to detect the viewing direction of the glasses wearer.
- the assemblies which ensure the actual function of such glasses are arranged in the glasses frame and not in the glasses. In such a
- Glasses frame is arranged a variety of electronic components in a limited space. It is therefore not possible to simply reduce or enlarge such a spectacle frame in order to adapt it to different people. Due to the mutual influence of neighboring arranged Such highly integrated electronic devices cannot be easily converted into electronic components, since factors such as crosstalk, capacitive or inductive coupling and shielding must be taken into account. Such glasses therefore have a “unitary frame”.
- Such glasses which are also referred to as eye glasses, are known from US Pat. No. 9,668,648.
- Eye detection cameras are arranged directly in the nose frame part, an adjustment via wire-supported nose pads is not possible.
- a further disadvantage of known methods for adapting glasses to a person's head is that the head parts of the person, in particular the nose, can be deformed during the fitting of the goggles, which results in poor fit of the goggles.
- the object of the invention is therefore to provide a method of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, with which eye-goggles can be adapted easily, contactlessly and precisely to an individual wearer, and which enables the eye-goggles to be worn for a long time and with little fatigue .
- eye-tracking glasses can be adapted to an individual wearer easily, contactlessly and precisely. Due to the high accuracy of fit, long and fatigue-free wearing of the gaze glasses is made possible. It has been shown that the nose pad is particularly relevant or central to the
- Nose shapes can be adjusted. This enables a very precise adjustment of the gaze glasses to an individual head.
- the at least one nose pad is modeled as a counterpart of the respective nose, in particular to the respective bridge of the nose, which ensures a very good fit
- Eye-catching glasses are reduced from the ideal position.
- the adaptation to very different nose shapes is possible without contact, which means
- the goggle goggles remain securely on the head even when the wearer moves quickly. This can cause a
- goggles can be quickly and precisely adapted to a wearer.
- very precise measurements or activities can be carried out with the goggles after just a short adjustment time.
- Eye-tracking glasses are often used alternately by several different people, so a short adjustment time is important.
- the adjustment can also be carried out by less experienced people, so that no trained optician is required.
- the invention relates to eye-goggles with at least one nose pad according to claim 9.
- the object of the invention is therefore to provide goggles with at least one nosepiece with which the disadvantages mentioned can be avoided, which can be adapted easily, precisely and without contact to a person.
- Figure 1 is an objective goggles with a nose pad and a nose pad holder in an axonometric exploded view.
- Fig. 2 the gaze glasses according to Fig. 1 in elevation.
- a topography of at least the nasal bridge of the person is recorded and topography data are created, in which
- the topography is recorded by means of a camera 8, 9, 15, which is moved in front of the face and to the side of the head of the person, in order to create unscaled topography data of the measured area of the head from several recorded images.
- the vision goggles 2, comprising a predefinable basic nose pad are arranged on the head of the person.
- At least one position value of the person's eyes is determined by means of the eye detection cameras 8, 9, the unscaled topography data being converted into scaled topography data on the basis of the at least one position value.
- Production data for at least one nosepiece 1 of the goggles 2 adapted to the bridge of the nose are created.
- Manufacturing data at least one nose pad 1 is produced.
- eye-tracking glasses 2 can be adapted to an individual wearer in a simple, contactless and precise manner. Due to the high accuracy of fit, long and fatigue-free wearing of the gaze glasses 2 is made possible. It has been shown that the nose pad is particularly relevant or central to adapting the gaze glasses 2 to different people.
- goggles 2 can be attached easily and without contact
- the at least one nose pad 1 is modeled as a counterpart of the respective nose, in particular to the respective bridge of the nose, as a result of which the seat fits very well
- Eye-catching glasses 2 is reached, causing the slipping
- Eye-tracking glasses 2 is reduced from the ideal position. Here is the
- Eye-tracking glasses 2 simply on different heads or faces, in particular to be adapted very precisely to different nose shapes.
- goggles 2 can be quickly and precisely adapted to a wearer.
- very precise measurements or activities can be carried out with the goggles 2 after only a short adjustment time.
- Eye-tracking glasses 2 are often used alternately by several different people, so that a short adjustment time is important.
- the adjustment can also be carried out by less experienced people, so that no trained optician is required.
- the present invention relates to the adaptation of a pair of eye-tracking glasses 2 to the head of a wearer.
- the adjustment is carried out by changing the seat of the gaze glasses 2 on the nose of the glasses wearer or user by changing certain dimensions at the contact points to the nose, their position or the seat on the nose of a certain, individual
- the nose pad 1 thus spaced the eyeglass frame from the nose and brings about the correct fit of the gaze glasses 2 on the bridge of the nose.
- the nose pad 1 as a contact zone or
- a topography of at least the nasal bridge of the person is recorded and topography data are created.
- the measurement step is carried out without contact, which means that the nose is not subject to any deformation during measurement.
- the topography data created in the measurement step reflect the surface of at least the bridge of the nose of the person.
- Modeling step is used to create manufacturing data for the at least one, preferably two, nosepads 1 of the goggles 2 adapted to the bridge of the nose from the topography data of the measuring step.
