Description

Device for detecting movements of a person using the device for the purpose of transforming the movements into a virtual space

The invention relates to a device for detecting movements of a person using the device for the purpose of transforming the movements into a virtual space. The device comprises a seat rotatably formed with respect to a ground on which the person using the device can sit, the seat being shaped such that at least movement of the legs from the knee to the distal end of the legs of the person using the device is possible, and Sensors that detect the movements of the feet of the person using the device. The invention further relates to a system for detecting movements of a person using the system and for transforming the movements into a virtual space. The system contains the

Device according to the invention and is adapted to the detected by the sensors movements of the feet in a synchronous, Richtungsidente and

to translate velocity-identical locomotion of a virtual avatar in virtual space, wherein the virtual avatar can be displayed in a virtual space displayed on a display means.

The document US 9,329,681 B2 discloses a system for detecting

Movements by a person using the system and transforming the movements into a virtual space, whereby the person in the system can move upright by walking. The system is essentially constituted by a substructure with a concave base, which is known as a

Footprint for a person using the system, and a frame for fixing and stabilizing the person using the system

Pelvic area formed. The pelvic area is fixed with a strap that surrounds the pelvis. This can give the person a high sense of security.

In the system known from the document US 9,329,681 B2 has proved to be disadvantageous that an "entry" into the system and an "exit" from the System is very uncomfortable due to the frame and the belt and thus time-consuming for the person.

The patent US 5,515,078 A discloses a system for detecting

Position information and display a virtual space based on the position information. The system comprises a computer, a base and a chair, whereby parts of the chair can be changed in position by the user of the system with respect to the base. These changes are detected by a measuring device. Furthermore, the system has a monitor which is attached to the chair and moves with the chair. Joysticks are attached to the chair or monitor. The joysticks and the

Position measuring device detected signals are evaluated by the processor and converted into the virtual space displayed on the monitor.

As a result, the system known from US 5,515,078 A does not detect directly the movements of the person using the system, but the movement of the elements of the chair or joysticks which changes the position of the person. An immersion of the person using the system, which describes an insertion of the person into a virtual body / avatar, is thus in this case only slight, if at all.

The utility model DE 20 2007 01 1 704 U1 discloses a device for controlling flat or three-dimensional objects which can be displayed on a display by means of a sensor device which exerts movements or loads exerted on a seating surface by a user and / or the movement or loads captured by one foot of the user. In particular, the sensor device is formed a movement, position, height, acceleration and / or inclination of the seat and / or different positions or

Orientations of the foot of the user to capture. The sensor device for detecting the positions and orientations of the foot is formed by a three-dimensional resilient rocker, which is changed by changing the pressure on the foot in its position. As a result, even in this device, the movements of the person using the device are not detected directly, but the movement of elements that moves the person is detected. In contrast to the aforementioned system, the advantage is obtained that the foot can additionally be used as an input device, but this only takes place as long as the foot gets up on the sensor device. A detection of movements of the foot when not on the sensor device upstanding foot is not described because the rocker can not move with the foot. An immersion of the person using the system is thus also given in this case, if at all, only slightly.

The present invention is based on the object, a device for detecting movements of a person using the device

to provide, in which directly the movements of the person, in particular the legs or feet of the person, are detected, during the use of body parts

wrap around fixing means is avoided and still given a great freedom of movement of all limbs of the person using the device.

According to the invention, the object of the present invention by a

Device solved in that the device comprises a seat with a support member, wherein the support member is adapted to that a seat member on which the person using the device can be attached to an upper part of the support member, and that the load of the seat member in the

Is substantially taken along a vertically arranged longitudinal axis of the support element and forwarded to a base, wherein the seat is rotatably formed with respect to the ground, and wherein the seat is formed so that at least one movement of the legs from the knee to the distal end of the legs the device using the person is possible. The device further comprises sensors which detect the movements of the feet of the person using the device and cyberfoot covers for receiving at least one of the sensors, the cyberfoot covers each having a sole and attachment means with which the cyberfoot covers are applied to the legs of the person using the device are attachable, and wherein the Sole of Cyberfußüberzieher is curved so that during the movement of the legs of the person using the device a continuous sliding rolling movement of the feet of the person using the device is possible.

The invention also relates to a system comprising the device according to the invention, wherein the system is adapted to the movements of the feet detected by the sensors in a synchronous, Richtungsidente and

to translate the speed-identical movement of a virtual avatar in virtual space.

The invention further relates to a method for producing the device according to the invention, comprising the steps of: providing the seat with the support element, which is adapted so that a seat element can be fastened to the upper part of the support element, providing the sensors, and providing the Cyberfußüberzieher.

For the sake of simplicity and for reasons of better clarity, the person using the device or the system will be abbreviated to person in the further course of the description.

In preferred embodiments of the invention, the device comprises a seat with a seat element which is fastened to the upper part of the support element.

When using the device according to the invention, the person sits at least partially on the seat, depending on the shape of the seat member of the seat at least a movement of the legs from the knee to the distal end of the legs of the person is possible. For example, in a seat element with a flat seat surface, for example a normal chair or an office chair, in the

Essentially only the movement of the legs from the knee to the distal end of the legs is possible. The thighs of the person lie essentially on the seat.

In a seat element in saddle shape, for example, the legs of the person already given a greater freedom of movement, the freedom of movement can be maximized in a seat element in Fahrradsattelform. The thighs The person lie while sitting only slightly or not at all on the seat and the sitting position is upright many times more than when sitting on a flat seat. The legs can be moved substantially holistically, with the legs of the person in rest position are only slightly angled. Theoretically, the seat, starting from a bicycle saddle shape, can be made even smaller, which further increases the freedom of movement of the legs, but no longer provides seating comfort.

Preferably, the seat member is formed so that the thighs of the person substantially or not predominantly rest on the seat member.

Alternatively, the person can achieve this result by changing the sitting position on a flat seat, so that the thighs can be moved as freely as possible.

Advantageously, to increase the safety of the person, the seat is provided with a backrest and / or an armrest.

Preferably, the support element is arranged along its longitudinal axis substantially below the center of gravity of the seat element. In some

Embodiments is the support element along its longitudinal axis in

Essentially arranged centrally below the seat element.

Preferably, the support element allows the rotation of the seat relative to the ground. For this purpose, the upper part of the support element is rotatably formed relative to a lower part of the support element. The support member can be made adjustable in length to regulate the seat height.

Preferably, the support element comprises a gas spring. The gas spring is rotatable about its longitudinal axis and is designed to be adjustable in length.

Preferably, the device according to the invention comprises a stand, which receives the support element and connects to the substrate. The stand may be a part of the support element. Preferably, the device according to the invention is designed so that the stand does not restrict the granted by the seat legroom of the person. In some embodiments, the device is configured such that a pedestal portion of the pedestal that provides stability to the device is positioned below a person's tread surface disposed about the seat. Alternatively, the

Tread surface be formed as a base portion of the stand.

In some embodiments, the device according to the invention comprises a formwork with which at least one base portion of the stator is clad. The formwork has a recess for the implementation of the support element and a means for fixing the stator. The tread surface is at the top of the

Formwork arranged so that the formwork acts as a pedestal whose areal extent is determined at least by the required range of motion for the legs of the person.

In some embodiments, a swivel chair is used as the seat, such as an office swivel chair, with the stand corresponding to the base of the swivel chair. In order not to restrict the legroom through the base, the foot of the swivel chair is preferably clad with the formwork and fixed within the formwork. The fixation is particularly advantageous when the base of the swivel chair is provided with rollers.

For a good walking feel, it is necessary that the seat height is a slight

Angulation of the legs allows. Depending on the size of the person, the intended length of the support element may not be sufficient to avoid excessive bending of the legs. In some embodiments, the device includes

Support element with a different from the standard dimensioning length. Alternatively, the device may be provided that the existing

Supporting element can be replaced by a support element deviating length. In other embodiments, the device is at least one more

Support element, for example, a longer gas (pressure) spring, attached to the exchange. In order to simulate the person a feeling as real as possible, the device according to the invention on Cyberfußüberzieher, which are slipped over the person's feet. The sole of Cyberfußüberzieher is curved, allowing a continuous sliding rolling movement of the person's feet.

Preferably, the curvature of the sole is adapted to the shape of the seat and thus to the freedom of movement of the legs of the person. The Cyberfußüberzieher are advantageously formed by any kind of shoes, Sandelen or socks. These can either be pulled directly over one foot of the person or pulled over an already put on sock and / or tightened shoe.

Preferably, the device comprises a tread surface which is arranged around the seat so that the person's feet can roll over the tread surface. The surface can rest on the ground. Alternatively, the tread surface is placed on a pedestal, such as a formwork for covering those parts of the device which provide stability to the device and otherwise restrict freedom of movement if located above the tread surface.

If the ground or the tread surface arranged around the seat is smooth, the soles of the Cyberfoot covers are advantageously covered with a textile in the form of a carpet. If the substrate or the tread surface has a surface formed by a textile, for example a carpet, the sole is advantageously designed to be particularly smooth and formed from metal and / or plastic, in particular from PE, PEHD, POM or PA. This has the advantage that despite physical contact Cyberfußüberzieher with the ground movement of the legs or the feet of the person without much effort is possible and that the system is very quiet.

The movements of the person, in particular the legs or the feet, are detected by sensors which are arranged in the operating position decentralized to the person, and / or sensors, which carries the person in operating position on the body. The decentralized to the person arranged sensors can, for example, by at least one optical sensor, in particular at least one based on infrared optical Sensor be formed. It is expedient in this context to attach active and / or passive motion capture markers to a person's clothing and / or to the cyberfoot covers. With active motion capture markers, there is also the possibility that only at least one light laser unit is mounted externally to the person, this being designed to emit different light pulses. The light pulses are detected by the active motion capture markers, and based on this, the person's movements can be calculated. Sensors worn by the person on the body may include, for example, magnetic sensors, acceleration sensors, proximity sensors, and / or optical sensors. Advantageous are magnetic sensors,

Acceleration sensors, proximity and / or distance sensors and / or optical sensors formed in the Cyberfußüberziehern. Furthermore, there is the possibility that the tread surface or the substrate is pressure-sensitive.

The advantages of the device according to the invention are that the sitting posture allows a secure sitting on the seat and a substantially free mobility of the legs and free movement of the hands. A support of the person on the hands and a body parts wrap around additional fixation to stabilize the person is not necessary in the device according to the invention. As a result, the comfort of getting in and out of the device is also very high and the person can move his hands freely. The person must be in the system according to the invention in

Basically just putting down or getting up. This also provides the advantage that people do not need to be trained on the device, but can intuitively use the device.

Appropriately, at least one rolling element is formed in the sole of Cyberfußüberzieher. The at least one rolling element is advantageously formed by a roller or a ball and is mounted by means of bearings in the Cyberfußüberziehern. Preferably, a rotation angle of the at least one rolling element is detected by means of a rotation angle sensor, in particular a Hall sensor. This has the advantage that a speed of the Cyberfußüberziehers is reliably detected by the at least one rolling element when placed on the base foot and at lifted foot from the ground after the expiry of at least one rolling element, the speed is zero. In this context, the Cyberfußüberzieher advantageous adjustment elements, for example in the form of

Set screws or foam pads on the at least one

Rolling element act and this braking. Suitably, a flow time of the at least one rolling element is adapted to a position of the at least one rolling element on the sole. The greater the distance between the toe of the person and the rolling element, the longer the flow time.

If the Cyberfußüberzieher only one rolling element, this is preferably in the vicinity of a rear third point of the underside of the sole of the

Cyberfoot covers arranged. The rolling element is preferably about 2

Mm above a smooth rounded bottom of the cyberfoot overcoat sole. This has the advantage that the Cyberfußüberzieher on a substrate or on a tread that is covered by a carpet or other textile, can slide well. A carpet or textile advantageously has such a pile height that the rolling element can easily push into the carpet, whereby the rolling element during a walking movement of the person has the longest possible contact with the ground or the tread surface.

It is an essential feature of the invention that the rounding of the sole of Cyberfußüberzieher, whether in the longitudinal or in the transverse direction, is tailored to the design of the seat. The slightly elevated sitting position of the person over a conventional chair causes a walking sensation when the legs are moved, even though the person is sitting. The weight of the person is thereby derived as when sitting predominantly over the seat, in contrast to a conventional chair only a slight bending of the legs of the person and thus a broad mobility of the thighs as when walking is given. After the stability of the person is caused by sitting, the Cyberfußüberzieher can be set to a particularly smooth rolling, because the executed walking motion does not have to support the stability of the person. This cyberfoot cover and seat work in a synergistic way together and allow the use of the device without the use of

Body parts wrap around fixatives.

It is important that the movements detected by the sensors are transferred in real-time to virtual reality in order to experience the experience of virtual reality as particularly true and close to the body. If the conversion of the movement of the person using the system is inaccurate, time delayed or highly abstracted, many persons experience nausea after a short time when using the system (VR nausea). Preferably, a linear relationship between the movement of the legs and the movement in the virtual space

making the experience particularly direct and genuine.

The advantages of the system according to the invention additionally consist in that a forward and / or backward movement in the virtual space can be triggered by the person in a direct manner by forward and / or backward movement of the feet. Wherein the forward and / or backward movement of an avatar in the virtual space is accomplished only with ground contact of a real executed foot movement.

In some embodiments, the device according to the invention is designed as a kit that can be assembled by a fitter.

Thus, the fitter can integrate a provided seat element into the device. The method according to the invention for producing a device for detecting movements of a person using the device can therefore be extended by the following preparatory steps: providing the seat element, and mounting the seat element on the upper part of the support element.

The seat element represents a seat that the installer of an existing

Remove seating and can mount on the support element of the device according to the invention. The inventive method for producing a device for detecting movements of a person using the device can be extended by the following preparatory steps: Providing a seating opportunity with the seating element, and disassembling the seating element from the seating area.

Laser triangulation 221 a capture. Figures 8a to 8c show in perspective view steps in assembling the seat 210 of the system 200a of Figure 3 and the system 200b of Figure 7. The seat 210 consists of the stator 201, a support member 203, which may be formed as a gas (pressure) spring and the saddle 205. The stand 201 has a slightly conically shaped skirt 202 into which the support member 203 is inserted, the support member 203 being fixed in the stand 201 by a weight of the person. In the tread surface 204, a recess is provided on an underside, into which the stator 201 fits. This has the advantage that the

Performance surface 204 can just rest on a floor and no one

Walking movement disturbing edges are formed. At the saddle 205, a lever 206 may be mounted, by means of which the seat member 205 is height adjustable via the support member 203. Advantageously, the tread 204 is provided on its surface with a carpet.

FIG. 9 shows a side view of the sandals 50a of the system 200b according to FIG. 7 in detail. The sandals 50a have a heel strap 61 formed by aluminum or plastic and two additional straps 62. The additional straps 62 are flexible and adjustable in length. Furthermore, the sandals 50a have passive motion capture markers 59, which are arranged distributed on the sandals 50a, a microcontroller, not shown, and not shown

Proximity sensors on. The proximity sensors detect a distance of the sandals 50a to the tread surface 204, wherein signals of the proximity sensors via the microcontroller to the central control means 10 are transmitted. Due to the Motion Capture Marker 59, the System 200b has a very high accuracy. A sole 58 of the sandal 50a is arched corresponding to the sole 71 of the sandal 50b shown in FIGS. 4a to 4b. Correspondingly, the sandals 50a, like the sandals 50b shown in FIGS. 4a to 4c, have a front region 21 and a rear region 51 in the longitudinal direction, wherein a radius of a sole 58 of the sandals 50a in the front region 52 is greater than in the rear region 51.

The sole 58 has on its underside a very low coefficient of friction, which in this embodiment of Cyberfußüberziehers no rolling element is necessary. Depending on the application, it may also be advantageous, the sole 58 of the Partially provide sandals 50a with elements or a coating which increase the coefficient of friction. An upper surface of the sole 58 is provided with a layer 60 which has a very high coefficient of friction. The layer 60 is formed by rubber, for example. This provides the advantage that the sandal 50a is better fixed to one foot of the person.

In a further embodiment variant, the sandals 50a have active motion capture markers which are activated by the microcontroller in the sandals 50a. For sandals 50a with active motion capture markers, the optical sensors 220a are advantageously not formed by sensors but by

Laser light units. The laser light units are designed to output different static and / or dynamic light pulses.

In a further embodiment, further motion capture markers are attached to a clothing of the person.

Figures 10a and 10b show in a lateral perspective view of the principle of a walking movement on the seat member 205 of the system 200a of Figure 3, the system 300 of Figure 6 or the system 200b of Figure 7. In a walking motion on the seat member 205, the person moves the knee joint , here indicated by the left foot, from a position Ka to a position Kb. Simultaneously with this movement, the person rolls his left foot over the

Underground under tightening of the ankle from, see difference angle Wa to Wb.

Systems and a person using the system.

FIG. 12 shows a perspective view of a further embodiment variant of the system 400 according to the invention in the installed position during use by a person, wherein the system 400 differs from the system 100 according to FIG. 1 only with respect to the seat element 405. The seat member 405 has the shape an office seat and has a flat seat. The system 400 further includes a tread surface 404.

It will be explained below with reference to FIG. 1 1 how a movement of a person using the system is transmitted to an avatar moving in a virtual space.

Depending on the variant, the speed of the person's feet is detected differently. In the system 100, 200a, 300 and 400, the

Speed of the feet determined by means of built-in Cyberfußüberziehern rolling elements and Hall sensors.

In the system 200b, the speed of the feet is detected by the sensor 220a. About the additional installed in the sandals 50a proximity sensors is determined whether by the person by means of the sandals 50a contact to

Tread surface 204 is made or not. The information is continuously transmitted via the radio network 13 to the central control means 10. In the central control means 10, the information is further processed so that, in the case of non-ground contact, the speed of the respective sandal 50a is set to zero and in the case of ground contact the speed is set according to a value which is being detected by the sensors 220a. As illustrated in FIG. 11 by means of arrows V1 and V2, both the left sandal 50a and the right sandal 50a have at the moment shown

Ground contact. The speed at this moment is higher for the left sandal 50a than for the right sandal 50a.

Depending on the embodiment, a direction vector R [X, Y, 0] of a

intended direction of movement of the person by means of the 3D glasses 14, by means of the rotation angle sensor in the gas spring 103 and / or an orientation of the

Cyberfußüberzieher be captured.

When determining the directional vector R [X, Y, 0] by means of the 3D glasses 14, a viewing direction B [X, Y, Z] of the person is permanently detected by the 3D glasses 14. The 3D glasses 14 are preferably formed by a commercially available 3D glasses 14. The viewing direction B [X, Y, Z] is continuously transmitted to the central control means 10. In the central control means 10, the Z-component of the viewing direction B [X, Y, Z] is set to zero and the components X and Y of the direction vector R [X, Y, 0] are calculated by means of an algorithm. This is the easiest way to determine an intended direction of movement of the person.

When determining the direction vector R [X, Y, 0] by means of the rotation angle sensor, the directional vector R [X, Y, 0] is determined via the orientation of the seat element with respect to the ground or the tread surface. The orientation of the saddle 205 corresponds to the orientation of the pelvis of the person. By determining the directional vector R [X, Y, 0] via the orientation of the seat element, the advantage is obtained that the person is simulated an even more real movement in the virtual world.

In determining the direction vector R [X, Y, 0] on the orientation of the

Cyberfußüberzieher by the central control means 10 both the current position of the Cyberfußüberzieher, as well as the current orientation of the

Cyberfoot coverers continually captured.

In a further embodiment, additionally the

Acceleration of Cyberfußüberzieher detected by acceleration sensors.

Using the obtained data of V1, V2, and R [X, Y, 0], a movement of the avatar is performed at each calculation pass through the central control means 10 as follows:

- From the speed V1 and V2, a speed of the person is calculated according to the following formula:

V = MAXIMUM VALUE (\ V1 \, \ V2 \) ^* SIGNATURE (V1 + V2) ^* (-1);

From V, a distance D to be traveled is calculated by multiplying V by a time interval between two calculation passes. Furthermore, the distance D to be covered can be multiplied by a correction factor k (for example, with a necessary conversion of centimeters to meters). Formula: D = V ^* (time difference between the calculation passes) ^* k;

- From the distance D and the direction vector R [X, Y, 0] is a

Translation vector T [X, Y, 0] is calculated by calculating an amount of the direction vector R [X, Y, 0] on the length of the distance D. That a negative one

Distance D causes a reversal of the direction obtained from the direction vector R [X, Y, 0], a positive distance D causes this direction to be maintained. Preferably, the conversion of the speed of the person on the distance covered by a graphic software of the central control means 10. In this regard, it is advantageous that the graphic software instead of the

Translation vector T [X, Y, 0] a directed average velocity is passed.

For each calculation pass, the avatar is advanced by the translation vector T [X, Y, 0] or according to the directional average velocity.

- In addition, the movement of the avatar can be smoothed with already known algorithms. In addition, there is the possibility that the avatar is limited and / or directed by means of customary software calculation in his movements. As a result, gravity or collisions can be simulated. The

The viewing direction of the avatar is controlled according to the usual methodology according to the viewing direction detected by the 3D glasses 14.

Figure 13 shows another general embodiment of the system 500 according to the invention and a person using the system 500. The system 500 has Cyberfußüberzieher and is equipped with a seat 1 10 according to Figures 2a-2c. Furthermore, the system may have a central control means 12 and may have a virtual display means, for example in the form of 3D glasses. The seat may also be formed according to a seat of another embodiment described herein or formed by a combination of elements of the seats described herein. The central control means 12 is formed in the right Cyberfußüberzieher, but can also in the left Cyberfußüberzieher, in the virtual

Display means or be formed in a separate housing.

It will be explained below with reference to FIG. 13 how a person using the system causes the avatar to move sideways, forwards / backwards, in the virtual space to move and / or to turn and / or to go around a bend. In this context, the movements of the feet of the person or the

Speeds of the person's feet, at least in X and Y coordinates, advantageously in X, Y and Z co-ordination, and / or respective rotations about these axes, with forward / backward movement of the feet substantially corresponding to the Y components sideways movement in the

Substantially corresponds to the X component and a movement along the

Vertical essentially corresponds to a Z motion. The coordinate system shown in FIG. 13 is a foot-fixed coordinate system, with only one of the fixed-coordinate coordinate systems being shown in FIG. 13 for the sake of simplicity.

The X component and Y component of the movement of the person's feet are advantageously detected as follows:

by means of at least one in a sole of Cyberfußüberzieher

arranged rolling element, wherein a rotation of the at least one rolling element is detected with at least one rotation angle sensor. The rotation angle sensor can be formed by an optical sensor, for example a laser, or a magnetic sensor, for example a Hall sensor. Preferably, the at least one rolling element is formed by a ball or by an all-side roll. Advantageously, a load sensor is additionally attached to the at least one rolling element, which detects a load applied to the at least one rolling element;

- By means of at least one decentralized to the person arranged optical sensor according to system 200b according to Figure 7, which detects at least the movements of the feet. With the at least one decentrally arranged optical sensor, a Z-component of the movement of the person's feet can also be detected;

- By means of at least two position sensors, each one

Position sensor is formed in a Cyberfußüberzieher. The position sensors advantageously determine their position by means of reference points arranged around the system.

and or - By means of at least two optical sensors, wherein in each case an optical sensor is formed in a Cyberfußüberzieher. The optical sensors are designed, for example, correspondingly optical sensor, which are also used in computer mice.

Based on the detected X-components and Y-components of the movements of the person's feet, the central control means determines whether the person

Wants to perform sideways movements, forward / backward movements, rotational movements or Kurvengehbewegungen. In this regard, it is advantageous pro

Cyberfußüberzieher at least one proximity sensor and / or at least one

Pressure sensor formed in the Cyberfußüberziehern. Suitably, the at least one proximity sensor and / or at least one pressure sensor is designed in the longitudinal direction of the Cyberfußüberzieher in the front region of the sole of the Cyberfußüberzieher. In particular, the at least one proximity sensor and / or

Pressure sensor formed in a region of the Cyberfußüberziehers, which, when the person wears the Cyberfußüberzieher, is located in the area of the ball of the person's foot.

In order to improve discrimination of the central control means between sideways movements, forward / backward movement, rotational or cornering movements, it is also possible to detect rotational movements of the feet about the Z-axis. This can be done, for example, by the external to the

Cyberfußüberziehern arranged optical sensors and / or two each arranged on a Cyberfußüberzieher optical sensors and / or rolling elements and / or position sensors done. By means of external to the Cyberfußüberziehern arranged optical sensors is also possible to detect rotational movements of the person's feet about the X-axis and Y-axis.

The conversion of the movements of the feet of the person using the system to the movements of the virtual avatar in the virtual space is performed by the central control means 12 according to at least one of the following criteria:

- Size of the X-component of the movement of the feet of the person in relation to the Y-component of the movement of the feet. Is the Y component of the As the person's feet approach zero and an X component exists, the virtual avatar moves sideways. If the X component of the person's feet movement is approximately zero and there is a Y component, the virtual avatar is moved forward / backward.

- Rotation of the feet about the Z-axis. A rotation of the feet about the Z-axis during a walking motion is a strong indicator that the person wants to cause the virtual avatar to make a turn-walk.

The size of the X component of the movement of the person's feet in relation to a person's rotational movement sitting on the seat. If an X component is present and the person is essentially sitting at the seat does not rotate against the ground, d. H. a rotation of the pelvis of the person is close to zero, the virtual avatar is moved sideways. If an X component is present and the person sitting on the seat is making significant rotational movement relative to the ground, i. a significant rotation of the pelvis of the person is detected, the virtual avatar is caused to make a rotation about its own axis. The rotation of the body center point is advantageously determined by the at least one decentrally arranged optical sensor and / or based on a rotation of the seat element 105 relative to a substrate by a rotation sensor on the seat 1 10. The rotation sensor is advantageously attached to the support element 103.

- Pressure on the sole of Cyberfußüberziehers. A compressive force on the sole in the front area of the Cyberfußüberzieher in the area of

Footpads of the person and a rotation of the body center of the person around his own axis is a strong indicator that the person wants to cause the virtual avatar to make a turn.

- In the presence of rolling elements in Cyberfußüberziehern

Load on the rolling elements. At a high load on the

Rolling elements and in the presence of an X-component of the movement of the feet, the virtual avatar is caused to make a turn. At a low load, ie at a load of approximately zero, on the rolling elements and in the presence of an X component of the movement of the feet, the virtual avatar is caused to

To perform sideways movement.

- distance of certain areas of the sole of Cyberfußüberzieher to

Document. Is a distance between front of the area

Cyberfoot overcoat is present in the area of the foot pads of the person and the pad, and there is an X component of the movement of the person's feet, the virtual avatar is moved sideways. If a distance between the front portion of the cyberfoot topsheets in the area of the footpads of the person and the pad is zero and there is an X component of the movement of the person's feet, the virtual avatar is caused to make a turn.

- Position of the legs. Are the legs of the person essentially

Angled at right angles and an X-component is present, the virtual avatar is moved sideways. Are the person's legs in

Being substantially outstretched and having an X component, the virtual avatar is caused to make a turn. The determination of the position of the legs is advantageously carried out by the at least one externally arranged optical sensor and / or the position sensors.

A Cyberfußüberzieher with a rolling element in the form of a ball 77 and a proximity sensor 78 is formed, for example in the form of a sandal 50d in Figure 14. The sandal 50d is otherwise substantially similar in structure to the sandal 50b of FIG. 4b, with parts which are the same in the sandal 50d as the parts of the sandal 50b of FIG. 4b are given the same reference numerals.
