     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0012]    Turning to  FIG. 1 , a schematic drawing is shown of a location based gaming device. In particular the gaming device  10  is shown to comprise a location control unit  1 , arranged to output location data. Typically, such a location control unit  1  may be provided by a global positioning system unit, known in the art, which receives location information from geostationary signals  2 . However, other positioning signals, including radio signals etc. may be used to receive location information. The location control unit is communicatively connected to a controller  3  and a light unit  4 . The light unit  4  comprises light sources  5 , which may display a light characteristic, controlled by controller  3 , such as light color, intensity and light pattern. As an example of a change of a light characteristic controller  3  is adapted to provide, for each light source  5 , a color transition. Herein, a color transition will be defined as a change in color states of the light source. A color state may be defined by a specific CIE XYZ coordinate, or coordinated in any derived color space, e.g. an RGB combination including white and amber (LED) light sources. This defines the perceived coloring of the light, in addition to a controlled intensity of the respective RGB sources  5  arranged in the light unit  4 . Otherwise, the light source  5  may vary the radiated wavelength, to generate a specific color in the visible light spectrum. Using high colored brightness LEDs, including white light, color states of substantially the entire visible color spectrum can be generated within a single visual segment  6  by light sources  5 . A memory  7  is coupled to the controller  3  to store track data, which may be prestored or received via a data port  8  (WIFI, infrared, USB, GPRS, UMTS or other digital connection). In addition, other data, such as game data or audio data may be stored, to be accessed by the controller  3 . The controller may further comprise user interface, such as a controller switch, a knob etc. to, further comprising a controller switch and/or a controller data port to select a number of controller game modes. 
         [0013]    The gaming device functions as follows: 
         [0014]    The location control unit  1  outputs location data to the controller  3 . The controller  3  calculates a proximity function indicating whether the location data match with the track data prestored in the memory  7 . For instance, if a user is within a predetermined range of a certain track, this may be regarded as ‘on track’, whereas, if the user is more than a predetermined distance, for instance several tens of meters, away from the track, this may be regarded as ‘off track’. Thus, the memory may prestore a sequence of locations, which may together form a track, and a sequence of directions, which may indicate a preference direction to move between the locations, and the controller  3  may be arranged to calculate a proximity function, and further change a light characteristic, such as a light color, a light intensity or light pattern, to signal an outcome of the proximity calculation. The following lighting behavior may be illustrative (in any particular combination): 
         [0015]    The controller  3  is arranged to provide full lighting intensity when the device is on route and decreasing intensity when leaving route; 
         [0016]    The controller  3  is arranged to change color depending on directions, e.g., green color when right direction, red color when wrong; 
         [0017]    The controller  3  is arranged to indicate a distance from the goal: e.g., blinking slowly when far from end goal, and faster when close; 
         [0018]    The controller  3  is arranged to indicate a proximity of target places: e.g., fast change of colors when close to special place; or 
         [0019]    The color is arranged to indicate a gaming response: e.g., flash certain color when ‘picking up’ certain object. 
         [0020]    A computing device  11  may be arranged, preferably communicating via signals  12 , for example, via GSM, UMTS, GPRS or the like. The computing device may function as a central game controller, typically communicating with several of gaming devices  10 , and arranged to compute at least a location of the gaming device, for example to project it on a digital map. Although the illustrated embodiment shows a one-way communication between computing device  11 , in an alternative embodiment the communication unit is a two way communication unit. It is possible to arrange the computing device to instruct the controller of the gaming device. This functionality may be used to further enhance the gaming possibilities, for example, to give an alert that torches are in the vicinity of each other, or that a certain person has performed a predetermined action with one of the gaming devices. The computing device may be a central unit but may also be arranged in (one of) the gaming devices for example, functioning in a master slave relation. In the latter case any gaming device may be arranged to function as a master computing device and/or slave computing device. However, a computing device may also be formed as a functional unit that is distributed over a plurality of gaming devices. 
         [0021]    As shown in  FIG. 2 , in an embodiment, the form of the torch  20  is formed as an elongate hand held body  21  in the form of a cylinder or inverted cone-shaped having a hand grip on a proximal side and having on the distal side a plurality of visually distinct lighting segments  6 . The segments  6  may be formed optically, by focusing optics confining light of a source to a visually distinct segments. It is possible to provide any number of segments  6 . The segments  6  are positioned around a central body axis. In each segment  6  a cluster of LEDs (see  FIG. 1 ) may be installed with different colors. Alternatively, other light sources, such as an incandescent light source may also be used or any other multiprimary light source, or color temperature adjustable light source. Of course, also monochrome LEDs can provide a light response. 
         [0022]    The system functionality of the  FIG. 2  is further exemplified in  FIG. 3 . The system elements of  FIG. 1  are indicated but not repeated. The device  20  may further comprise a gesture recognition module  26  for detecting predefined gestures; the controller  3  is further arranged to control the light characteristic as a function of a detected gesture. Thus, for instance, by ‘picking up’ items, or by ‘waving’ the torch, or by ‘throwing a spell’, different sensory responses can be activated by the controller  3 . In the example of  FIG. 2 , the gaming device  20  comprises an electronic compass unit  25 , arranged to output compass directional data to controller  3 . The handheld elongated body facilitates pointing the compass in a direction, to further identify whether a user is heading on a right track. To promote reliable indication of the direction irrespective of angular tilt of the body, a plurality of compass units may be arranged at an angle respective to each other, and wherein the controller  3  is arranged to select a compass unit that is oriented in a functional working condition. For instance, by pointing the device  20  in different directions, the controller  3  may be arranged to control the light unit response as a function of stored track directional data. Thus, when pointing the device  20  in the right direction according to a prestored ‘on track direction’, a specific ‘on track’ color such as green may be shown; and when the direction is wrong, the ‘off track’ color, such as red may be signaled. This further enhances the game possibilities since the user may intuitively be redirected to the right track, without having to read maps. The light unit response depending on the electronic compass indication may be activated in response to the gesture module  26 , in particular, when the gesture module senses that the torch is tilted. This prevents in adverted signaling due to rotations or movements of the torch  20  when used. Specifically, the gesture module  26  may comprise a tilt sensor and/or acceleration sensor (not shown). 
         [0023]    The invention is not limited to only light as output, but covers sound (sounds capes), smell, vibration and tactile output as additional game modalities as well. In particular, the torch  20  may comprise an acoustic unit (preferably including a loudspeaker  22 ) and/or a vibrational unit  23  activatable in response to the controller  3 . The torch  20  may further include batteries and a game port  8  to load track data; game software etc. 
         [0024]    Furthermore, where the embodiment discusses an elongated torch like body, other embodiments may be feasible, wherein, for example, the functionality is incorporated in a light ball, spectacles or a hat. 
         [0025]    Additional features may include: 
         [0026]    Touching of an interactive ‘poster’ to select a game or new assignment. This can also be triggered by entering a GPS location or pointing in a certain direction using the digital compass. 
         [0027]    Touching of torches to hand over items from the inventory, activate things, battle against each other, forward a color, give a function to somebody else et cetera. 
         [0028]    Use gestures to throw (virtual) things to a direction. E.g. a magic spell. 
         [0029]    Use the torch to set out a route. 
         [0030]    Shake gesture to lose items from the inventory. 
         [0031]    Dimming the light (and turning it on again) by blowing or covering it with your hands 
         [0032]    The invention also covers a combination of these game features. More in particular, it may be understood that the invention also covers embodiments, without express indication to the contrary, of combined features as described here above.
