Definitions
- the present invention relates to a device for generating a haptic
- the ultrasound signals of which can be tuned in terms of phase, frequency and amplitude.
- the invention further relates to a method for configuring and controlling such a device.
- Controls By actuating such control elements, the user receives immediate haptic feedback via the sense of touch on his hand or fingers, so that the duration and pressure with which the control element is acted on can be perceived directly.
- VR virtual reality
- AR augmented reality
- holographic environments in which any objects, devices and / or user interfaces are virtually displayed by suitable display systems.
- the devices mentioned at the outset were developed which, by means of controlled ultrasound loudspeakers, generate an area which can be perceived by sound in terms of their phase, frequency and amplitude at predeterminable points of an interaction space. The sound acts directly on the hand and can be felt and felt here.
- Such a device with a planar arrangement of ultrasonic loudspeakers is described, for example, in WO2016 / 038347 A1.
- Currently known devices for generating a haptically perceptible area of a virtual object have a large number of ultrasound loudspeakers, which are arranged areally on a common plate. The extends above the plate
- holographic environments often the preferred positions of the imaging devices and the preferred positions of the ultrasound speakers, so that compromises must be made, which reduces the accuracy of the effects produced.
- the interacting hand can only be stimulated with a planar arrangement of the ultrasonic loudspeakers from one direction, so that the palpable effect on the palm of the hand decreases or disappears completely when the hand is twisted.
- the known ultrasound loudspeaker arrangements cannot be combined satisfactorily with the likewise known imaging devices.
- the manual configuration of the ultrasound loudspeakers or the ultrasound signals has proven to be very complex and therefore time-consuming and prone to errors.
- the ultrasound speakers individually or in groups form a plurality of modules which can be positioned or arranged on the interaction space in such a way that
- Ultrasound speaker of another module is oriented and / or
- At least one ultrasound speaker of a module is spaced from a common plane of other ultrasound speakers and / or
- the modules are at a selectable distance from one another. Due to the positionability and thus the freely selectable position of the individual modules with ultrasonic loudspeakers, the device can be optimally adapted to the existing installation space, which is why a collision of the preferred positions of the image-generating devices and the touch-generating devices is avoided.
- the arbitrary, in particular angular arrangement of individual loudspeakers and / or modules relative to one another results in an optimal three-dimensional alignment of the modules in space, which can be arranged at any position outside the interaction space and aligned in the desired orientation.
- An individual design of the device for generating the haptic feedback can thus be realized with an optimal use of the available installation space.
- the device with essentially freely positionable modules has a minimal space requirement and, in particular, because the orientation of individual modules can be adjusted, a high degree of customization of the strength of the haptic effect can be achieved.
- the ultrasound loudspeakers of a module are arranged on a common module level.
- the ultrasound loudspeakers of a module preferably have an orientation oriented parallel to one another.
- the specific design of such a module is not specified in particular with regard to the number and arrangement of the ultrasound loudspeakers and is essentially arbitrary, but in practice there has been a matrix-like arrangement of the
- Ultrasound speakers proved to be advantageous.
- they are square
- Matrix arrangements of, for example, 4x4 ultrasound speakers are preferred.
- the device has at least three modules, the module levels of which are oriented at an angle to one another.
- the modules can be optimally arranged around the interaction space and aligned with the interaction space due to the installation space.
- a control unit with software (firmware) and a software included thereon is preferably
- the control unit calculates the individual ultrasonic signals in depending on the individual module positions and module orientations In relation to their phase, frequency and amplitudes in order to create a region with haptic feedback at any point in the interaction space. If such an area is to be created at several points, suitable groups are formed from the existing modules, which are assigned to a specific point and which generate the haptic feedback at this point. Because with the present three-dimensional
- the haptic area can be felt even with different hand orientations and any shadow areas within the interaction space can be effectively avoided.
- Control unit possible, so that simple and therefore inexpensive modules can be used in this case.
- all cable lengths and signal propagation times must be known or the same length.
- each module has a separate microcontroller for configuration and / or control of the ultrasound loudspeakers of a module and for communication with the control unit. This results in an optimal networking of the modules with the control unit designed as the main control unit and the communication is via a
- a plurality of ultrasound microphones are provided, which are directly on the modules or freely in the room
- the ultrasound microphones result in a simple automatic
- Configurability of the device and the ultrasound microphones can also be used as a three-dimensional acoustic camera with which objects within the
- Interaction space can be recognized, identified and tracked by a continuous position determination. This can result in an otherwise required
- Image capture device for example in the form of a stereo camera, can be dispensed with. This will be discussed in more detail in the description of the method according to the invention.
- the modules emit test signals which are defined one after the other and which are immediate and / or after a reflection on one or more reflection bodies of Ultrasound microphones are registered which are arranged directly on the modules and / or freely in the room, so that the relative positions and orientations of the modules and ultrasound microphones result from the transit times and / or the intensities of the registered test signals. Taking into account the positions thus determined and known
- Orientations of the modules and of the ultrasound microphones arranged thereon can advantageously be coordinated with respect to their phase, frequency and amplitude in such a way that areas which can be perceived haptically at any point within the interaction space can be generated.
- the ultrasound microphones self-calibrate the device, which simplifies the configuration of the device, which can be carried out essentially automatically without manual specifications.
- the accuracy and resolution of the configuration increases with an increasing number of modules and / or ultrasound microphones. Therefore, at least three are preferred
- Ultrasound microphones are provided, which can be arranged essentially freely distributed in the room. If the ultrasound microphones can be freely positioned, there are also the advantages that the positions are not limited to the module positions and, consequently, the amount of ultrasound microphones used and the different directions - i.e. their angles to measuring elements - can be increased as desired, which increases the detection range and accuracy of the procedure increased.
- the ultrasound microphones can also be used as an acoustic camera with which objects within the interaction space can be identified, identified and tracked by means of a continuous position determination.
- the ultrasound microphones can also be used as an acoustic camera with which objects within the interaction space can be identified, identified and tracked by means of a continuous position determination.
- reflections from stationary or moving objects within the interaction space - such as, for example, a hand that engages in the interaction space - are registered by the ultrasound microphones and the position, shape and movement of the object are determined from the reflected signals.
- the ultrasound frequencies can be used for the detection and tracking of the objects within the interaction space, which frequencies anyway generate the haptic effect
- Ultrasound speakers are given. Alternatively, other frequencies that deviate from this can also be used.
- objects can be determined using existing classification algorithms, which compare the reflected signals with existing and object-related data sets and, with a given match, allow the object to be clearly assigned. This also enables specific and targeted excitation of the object within the interaction space.
- a specific embodiment of the present invention is explained below with reference to the figure, which shows a schematic representation of a device for generating a haptically perceptible area of a virtual object within an interaction space with a plurality of ultrasound loudspeakers.
