Description

COMPUTER SYSTEM AND A 3D MARKER THEREFORE
TECHNICAL FIELD The invention on the one hand relates to a 3D (three dimensional) marker for a computer system, by which marker various manipulations can be carried out in a 3D environment as well as commands and data can be inputted into programs running on the computer system. On the other hand, the present invention relates to a computer system suitable for free-hand modeling by means of the 3D marker.
BACKGROUND ART
3D markers are understood as input devices providing for the computer system - relative or absolute - spatial positions having three or more degrees of freedom, i.e. positions with or without orientation. The term "computer system" relates to any and all systems comprising a unit for carrying out computing operations. Therefore, the computer system may be e.g. a gaming console, a system executing special scientific functions, or any other device or system.
2D as well as 3D markers suitable for inputting various manipulations and commands in a simple and ergonomic manner into programs running on computer systems have long been known in the computer technology. Such markers are e.g. the mice, the joysticks or the touch pads. According to the present art, these markers are equipped with two-state manipulation element(s), preferably arranged as two-state push buttons. These two-state manipulation elements provide extremely limited manipulation possibilities, so that the functions of the manipulation elements, as well as the parameters of such functions are to be configured and specified prior to the manipulation by other means, such as via a keyboard. In light of the above, prior art markers with two-state manipulation elements are extremely cumbersome and slow in their operation in a 3D environment.
A computer system suitable for performing 3D manipulations as well as a marker therefore are disclosed by way of example in WO 2005/116809 A2. DESCRIPTION OF THE INVENTION
It is an object of the present invention to provide a 3D marker for a computer system, which eliminates the deficiencies of the prior art. It is a further object of the invention to provide a marker, which is easy and inexpensive to manufacture whilst providing great freedom of manipulation in a 3D environment. It is another object to provide a 3D marker simple and ergonomic in its use. Yet another object of the invention is to provide a computer system suitable for free-hand modeling by means of the inventive 3D marker.
The characteristic features of the 3D marker according to the present invention are defined in claim 1 , while the characteristic features of the inventive computer system are specified in claim 6. Preferred embodiments of the marker and the computer system are specified in the dependent claims.
BRIEF DESCIPTION OF THE DRAWINGS
Exemplary preferred embodiments of the invention are described with reference to drawings, wherein
Fig. 1 is a three-dimensional view of an inventive 3D marker, and Fig. 2 is a three-dimensional side view of the 3D marker according to Fig. 1.
MODES FOR CARRYING OUT THE INVENTION
The invention is based on the recognition, that if instead of a two-state manipulation element, the 3D marker is fitted with a multi-state manipulation element, then operation in a 3D environment will be made more efficient and simple.
According to the preferred embodiments illustrated in Figs. 1 and 2, the 3D marker 10 comprises a body 11 having outwardly projecting protrusions 12A1 12B, 12C and 12D. Light sources 13A, 13B, 13C and 13D are arranged at the ends of the protrusions 12A, 12B, 12C, and 12D, respectively, for tracking the spatial placement (position, orientation) of the 3D marker by means of appropriate sensors. The body 11 is arranged ergonomically so as to be suitable for being held and for performing three-dimensional manipulations. The 3D marker is preferably connected to a computer system by means of a cable (not illustrated) attached to the end of the body 11.
In the way as seen in Figs. 1 and 2, the 3D marker 10 according to the present invention comprises a multi-state manipulation element 14. The multi-state manipulation element 14 is preferably formed as a spring return push button having a large number of intermediate states between its idle and fully depressed states, which follow one another either in an analogous way continuously, or in a discrete way. Apart from being a push button, the multi-state manipulation element 14 can be of course formed as a slider or any other similar, ergonomic element.
Additionally to the multi-state manipulation element 14, the 3D marker 10 may preferably be provided with an additional two-state push-button 15 for inputting signals, commands and instructions into the computer system.
The 3D marker 10 supplemented with the multi-state manipulation element 14 is extremely efficient for use in 3D free-hand modeling, game control, three- dimensional navigation or any other software control functions. In game control functions, by way of example, the multi-state manipulation element 14 can set the speed for the position adjusted by the 3D marker, in case of 3D freehand modeling, the intensity of the specific action (e.g. opening airbrush, radius of clay sphere) can be adjusted therewith. By means of the multi-state manipulation element 14, these parameters can be fine-tuned in small steps or continuously adjusted, resulting refined operations and greater efficiency and ergonomics.
It is a further advantage of the present invention that it allows continuous adjustment of the parameters parallel to executing other activities, thereby enabling more information to be delivered to the computer or computer system, in a more intuitive way. In case of free-hand modeling, where, by way of example, a shape of a virtual object is continuously changed, the parameters of the specific virtual shaping device can be set, which effects the virtual object. Therefore, the computer system also comprises a program means configuring one or more parameter(s) of the virtual shaping tool based on the input entered by means of the multi-state manipulation element 14, which program means is preferably a program module processing the input signal delivered by the multi-state manipulation element 14. If1 by way of example, a sphere is the virtual shaping tool being controlled by the 3D marker 10, then refined shapes can be modeled on the virtual object or shape-adjustments of a greater scale can be achieved by the mere dynamic adjustment of the radius of the sphere by means of the multi-state manipulation element 14. In this case, therefore, the parameter of the virtual shaping tool adjusted by means of the multi-state manipulation element 14 is the virtual spatial dimension (i.e. size) of the virtual shaping tool. However, any other form of virtual shaping tool may evidently be used. Furthermore, not only the size, shape or radius of the virtual shaping tool may be dynamically configured, but also further parameters thereof, e.g. intensity, type, character, distribution or any other characteristic feature of the effect. The multi-state manipulation element 14, can regulate e.g. the acuteness or obtuseness as well as stretching of the virtual tool or may modify the rate of surface smoothing, or the speed of edge contraction.
The multi-state manipulation element 14 may be used for applying smoothings or delays. If, for example, a tapering form (e.g. a horn) is desired to be created in a 3D space, it may be advisable, if a state of the multi-state manipulation element 14 - resulting in a smaller shape of the virtual object - is continuously, gradually acquired. Further, the same method may be used for offsetting any eventual shaking of the hand. State smoothings and delays of the multi-state manipulation element 14 can be executed digitally (by means of an algorithm) or electronically (e.g. by means of a condensator), or by a combination of these solutions.
More than one multi-state manipulation element 14 can also be arranged on the 3D marker. The multi-state manipulation elements 14 may be combined with each- other, for example, by means of a push button arrangement, that can separately detect how much it is depressed and can separately detect how much it is tilted forward or backward. In such a case a plurality of parameters can be controlled simultaneously. In case of a virtual shaping tool, by way of example, the state of depression of the push button may determine the size of the virtual shaping tool and the forward or backward tilted state may adjust the obtuseness or acuteness of the virtual shaping tool. In this case, a first multi-state manipulation element 14 is arranged for altering a first parameter of the virtual shaping tool, and a second multi-state manipulation element 14 is arranged for altering a second parameter of the virtual shaping tool.
The multi-state manipulation element 14 according to the present invention is preferably arranged as an analogous push button, however any other solution may also be used. According to the present invention the attribute of "multi-state" refers to more than two states, the number of which states preferably is three, more preferably at least ten, and most preferably at least a thousand. The multi- state manipulation element 14 may be arranged with analogous or discrete intermediate states. By way of example, the multi-state manipulation element 14 may be manufactured with a potentiometer or a pressure sensor. An especially preferred embodiment is the application of an optical gate comprising a light source and a light detector, as well as a light aperture operated by the multi-state manipulation element 14 arranged in between.
The invention is of course not limited to the preferred embodiments detailed above, but further versions and modifications are possible within the scope defined by the claims.
