Abstract

An alignment sensor system comprising: a movement apparatus (1) for performing movements by center of gravity displacement or muscle action of a human body, having an alignment member (2), and a mass production sensor (4) fixed relative to the alignment member (2).

Description

The present invention relates to an alignment sensor system and an orientation sensor method for a movement apparatus for performing movements by center-of-gravity displacement or muscle operation of a human body.

From sports equipment development training equipment for use in gyms are known, such as treadmills, stepper or bicycle ergometer. On this sits or stands a user and performs predetermined movements. It should be burned by the physical activity calories, achieved a training effect, and fun for the user to be generated.

Furthermore, game consoles such as a Nintendo ^Wii® or a Sony PlayStation ^{Move® are} known in which the user performs physical movements that are detected by a sensor. In the former, control modules are guided in one or both hands, whose position and orientation are determined by means of acceleration sensors in the control modules and an optical detection of the control modules and transmitted to the game console. In the latter, the body or body components are detected by means of multiple cameras, determines their location and orientation and transmitted to the game console. As a result, a game on a TV screen can be influenced or controlled.

Furthermore, 3D cinemas are known in which films are shown with a three-dimensional effect in order to offer the viewer a realistic as possible movie experience. Through a 3D effect on films, the action on the screen should look more real and let the audience forget that he is in a movie show. He should as far as possible become part of the action himself.

Furthermore, simulators are known in which a user controls, for example, a Formula 1 car or a racing motorcycle, wherein the user instead of a real windshield, a system of computer monitors is available. Furthermore, a realistic driving experience can be increased by the fact that the user takes place in a realistic simulated vehicle cockpit and the controls differ only slightly from those of a real vehicle.

Furthermore, video glasses are known, which are arranged and fixed on the head of a user ("head mounted display", hereafter HMD), such as Oculus Rift ^™ or HTC Vive ^™ . A virtual reality can be visually displayed on such a video goggle, whereby a user behaves during the use of such a device as if he could look around in the virtual reality and move freely in it. As the user alters the orientation of his or her head, and thus the video goggles, a stationary sensor system detects the orientation change of the head and goggles and redirects orientation change direction and velocity to a computing unit that computes the video image displayed by the video goggles accordingly a user the impression arises, as if he could actually look around in the virtual space or even move.

Furthermore, flight simulators are known for pilot training, which simulate a true-to-original cockpit on the one hand, but also simulate the actual movements and accelerations that act on a real cockpit during flight, take-off and landing. This happens, for example, in that the cockpit is arranged on a movement platform, such as a tripod or otherwise gimbal-mounted, and the cockpit can be moved, tilted and accelerated by the movement platform in different directions.

In the patent application not published at the time of filing DE 10 2014 223 447.8 For example, a device for performing movements by gravity displacement or muscle action of a human body is known, wherein a user causes a center of gravity displacement by the movement of his hip area while the user is supported on the device, and a movable part of the device including his own body into different ones Directions. While doing so, the user may wear video glasses and move through and interact with the overall video eyewear and motion device system in a virtual environment. The movements caused by the user can be generated solely by gravity by shifting the center of gravity. This movement device is a device that changes its orientation passively by user action and does not specify itself controlled.

By combining such a movement device with an HMD, it is possible, for example, to simulate a hang glider flight for the user, whereby an alignment change of the motion machine caused by body centering displacement is evaluated to control the simulated hang glider, and by the HMD an image reproduction adapted to the alignment of the head the simulation takes place.

The problem here is that both the orientation of the moving machine and the orientation of the head must be detected independently to allow this or a similar simulation. Thus, the orientation of the head is ultimately the sum of the orientation of the machine and the orientation of the head relative to the orientation of the machine. An HMD-enabled acquisition of the absolute head orientation does not allow conclusions about the orientation of the machine and thus of the user's body.

It is an object of the invention to provide an apparatus and a method to allow the determination of the orientation of such a moving machine cost.

This object is achieved with a system and a method according to the independent claims. Advantageous developments are the subject of the dependent claims.

By using a mass production sensor, in particular a smartphone for detecting the position of an alignment element of a movement machine, a high-quality alignment detection is possible with cost-effective means.

If a conventional computer is used to determine the orientation of a display unit, in particular a video eyeglass and to determine an image for the display unit, a powerful system can be provided with inexpensive standard components.

If another smartphone is used instead of the video glasses and the calculations for the display of this smartphone or the mass production sensor are made, the complexity of the system can be reduced and the user comfort can be increased.

The alignment element 2 is a horizontal longitudinal axis 11 to a transverse axis extending horizontally and perpendicular to the longitudinal axis 12 and optionally a vertical and thus vertical to both previous axes vertical axis 13 rotatable about a pivot point formed by the common intersection of the axes. In the exemplary embodiment, the vertical axis is strictly vertical. The vertical axis can also be around the transverse axis 12 be tilted forward or backward.

The direction and position indications "front", "rear", "left" and "right" used below refer to the orientation of the movement device and are as follows: "front" describes the side of the movement device on which the 1 related left end and up 4 covered upper end of the longitudinal axis 11 lies; "Rear" describes the side of the movement device where the on 1 related right end and up 4 related lower end of the longitudinal axis 11 lies; "Right" describes the side of the movement device where the on 1 related left end and up 4 referenced right end of the transverse axis 12 lies; "Left" describes the side of the motion device where the on 1 related right end and up 4 related left end of the longitudinal axis 11 lies.

The alignment element 2 has a support device 20 for a user's body. The support device 20 has handle elements 21 , Armschalen 22 and leg shells 24 on. At the rear end of the alignment element 2 are footpegs 25 arranged, through which a user can rest with the soles of the feet. In each case a handle element 21 and an arm cup 22 One side are immovably fixed relative to each other and form a handle unit 23 , One leg shell each 24 and a footrest 25 One side are immovably fixed relative to each other and form a foot unit 26 , Through this support device 20 becomes the body of a user on the motion device 1 supported.

The individual parts of the support device 20 are attached to a frame element 27 tethered. The grip units 23 and the foot units 26 are by a rail element 28 with the frame element 27 connected, causing the handle units 23 and the foot units 26 within fixed limits in the longitudinal direction of the movement device 1 can move. The individual elements of the support device 2 can work together with the frame element 27 around the transverse axis of the device 1 to be tilted around a bearing, with which the frame element 27 with another support element in circle segment shape, the arch element 29 connected is.

It has a base plate for this purpose 31 on, the non-displaceable in operation or rotatably mounted on a base, such as a room floor. The basic element 3 also has a support column 32 on, perpendicular to the base plate 31 extends upwards. At the upper end of the support column 32 is a warehouse 33 , In the exemplary embodiment, a roller guide arranged over which the alignment element 2 is stored so that it is aligned at least about the longitudinal axis 11 can rotate about a pivot point formed by the intersection of the axes. The roller guide 33 has an arcuate arrangement of two roller elements 34 on which the arch element 29 is stored, wherein additionally at least one roller 35 in the vertical direction over the arch element 29 is arranged to secure these components in a vertical direction.

Furthermore, the longitudinal axis extends 11 horizontal in this embodiment. It would also be conceivable that the longitudinal axis 11 tilted down or up. The transverse axis 12 is in this embodiment with respect to the frame member 27 fixed arranged. If the frame element 27 around the longitudinal axis 11 is tilted, tilts therefore also the transverse axis 12 of the device. If the alignment element 2 already around the longitudinal axis 11 is tilted, there is a further tilting of the support device 20 together with the frame element 27 Therefore, the also tilted transverse axis 12 ,

The support element in circle segment shape - the arch element 29 - does not necessarily have to be executed in circular segment form. This support element may in another embodiment, for example, follow in its shape any curve function. It would also be conceivable, the arc element 29 not as a circle segment but as a closed circle. In such an embodiment, it could be possible for the user to complete a full rotation around the longitudinal axis with the device.

In this view, it is easy to see that the frame element 27 has two parts, which are arranged on the right and left side of the figure. The individual parts of the device 1 can be made of different materials. For example, from carbon fiber reinforced plastic, conventional plastic or metal. In a preferred embodiment, the entire construction of the device is as light as possible. By a low mass, in particular the moving parts of the device, the ease of use for the user can be increased because tilting can be brought about easier.
