The computing device 104, in some embodiments, may exchange data with the network 112.
The projector tracking system 108 includes a first imaging device 126 and a second imaging device 130, although it is contemplated that the projector tracking system 108 can include any number of imaging devices. The projector tracking system 108 generally captures, projects and processes imaging associated with in-vehicle gaming. The imaging devices 126, 130 can be any electronic imaging device known in the art configured to project virtual images and capture virtual and real image data. Exemplary imaging devices include, but are not limited to, digital cameras, digital video cameras, projectors and imaging sensors. The first and second imaging devices 126, 130 can be mounted in the vehicle 102.
Referring now to FIG. 2, a vehicle interior 200 (i.e., an environment) of the vehicle 102 implementing a system for virtual gaming according to an exemplary embodiment is illustrated. The interior 200 of the vehicle 102 can include a first front seat 204, a second front seat 206 and a rear seat 208, though other configurations could be provided. A first vehicle occupant 210 and a second vehicle occupant 212 are seated on the rear seat 208. A first imaging device 214 is mounted to the left of the first vehicle occupant 210 and a second imaging device 216 is mounted to the right of the second vehicle occupant 212. The first and second imaging devices 214, 216 are used to project and capture images in the vehicle environment 200, for example a first image 218 and a second image 222, for in-vehicle virtual gaming.
In the illustrated embodiment, the first and second imaging devices 214, 216 are laterally spaced from one another. However, it is appreciated that the first and second imaging devices 214, 216 can be mounted in or on other various locations within the cabin of the vehicle 102, for example, the vehicle ceiling (not shown), the rear seat 208, a head rest of the first front seat 204 or the second front seat 206, a vehicle floor 220, among others.
One having ordinary skill in the art will understand that other imaging devices located in, on or controlled by the computing device 104 can be used in conjunction with the first and second imaging device 214, 216 for in-vehicle virtual gaming. Further, the portable device 110 can also include an imaging device (e.g., a camera phone) that can be used in conjunction with the first and second imaging device 214, 216 for in-vehicle virtual gaming. The projector tracking system 108 and/or the processor 114 can be configured to receive signals from the aforementioned other imaging devices to process with the signals and/or position data received from the first and second imaging device 214, 216.
FIG. 3 illustrates a side view of the vehicle interior 200 of FIG. 2 including a vehicle occupant 300 (e.g., a first or second vehicle occupant 210, 212 of FIG. 2) and an arm rest 302 located adjacent to the vehicle occupant 300. An imaging device 304 is located in the arm rest 302 and includes an image projection mechanism 306 and an image capture mechanism 308. By using multiple imaging devices, with dual image capture and image projection mechanisms, detection and projection of virtual images is facilitated by shadow occlusion as is known in the art.
Although the image projection mechanism 306 and the image capture mechanism 308 are positioned vertically spaced from one another in the illustrated embodiment, one having ordinary skill in the art will appreciate that other positioning arrangements are possible. Further, it is appreciated that the image projection mechanism 306 and the image capture mechanism 308 can be integral components of the arm rest 302 as shown, or as separate components of the arm rest 302.
Referring again to the system 100 and the computing device 104, the processor 114 (e.g., a controller, ECU) can include a game module 122 and an image module 128 for implementing in-vehicle gaming. It is appreciated, that in some embodiments, the projector tracking system 108 could include and/or perform the functions of the game module 122 and/or the image module 128 using the processor 114 or a separate processor integrated with the projector tracking system 108. In further embodiments, the portable device 110 or the network 112 could also perform the function of the game module 122 and/or the image module 128 by communicating with the computing device 104 or processor 114 or the projector tracking system 108.
In the illustrated embodiment, the processor 114 is configured to transmit, receive and process signals from the memory 116, the input/output interface 124, the disk 120, the vehicle systems 106, the projector tracking system 108 and the portable device 110. The game module 122 and the image module 128 execute and perform functions in conjunction with the processor 104 for in-vehicle virtual gaming as described throughout.
Referring now to FIG. 4, a computer implemented method of virtual gaming in a vehicle is shown according to an exemplary embodiment. In particular, the method will be described in association with the computer system 100 and FIGS. 1-3, though it is to be appreciated that the method could be used with other systems. At step 402, the method includes detecting a first set of image position data defining a first position of images projected on a game surface. The images can be virtual images (e.g., images 218 and 222), projected, by for example, the image projection mechanism 306, or real images (i.e., other objects in relation to the game surface). The image capture mechanism 308 can detect images and extract position data defining a position of the images.
The game surface is an environmental surface of the vehicle. Exemplary environmental surfaces include, but are not limited to, the floor 220 and a back of the first front seat 204 and/or a back of the second front seat 206. In particular, the environmental surface of the vehicle 102 can include at least one of or both the floor 220 of the vehicle, the back of the first front seat 204, and the back of the second front seat 206.
At step 404, the method further includes detecting a set of player position data defining a gesture or a position of one or more players relative to the first set of image position data and the game surface. For example, in FIG. 2, the first and second imaging devices 214, 216 can detect gestures or motions of the first vehicle occupant 210 and/or the second vehicle occupant 212 with respect to the game surface (i.e., the vehicle floor 220) and/or the first set of image position data, for example, the image position data associated with the images 218, 222. The image capture mechanism 308 can be configured to detect the set of player position data using techniques known in the art (e.g., gesture recognition, facial recognition, etc.). In another embodiment, the gestures or positions of the one or more players can be monitored or tracked by the image capture mechanism 308.
At step 406, the method further includes calculating or processing a second set of image position data based on the first set of image position data and the set of player position data. The second set of image position data represents the output (e.g., position) of virtual images based on the original position of the images (i.e., defined by the first set of image position data) and the interaction of the players (i.e., defined by the set of player position data).
The game module 122 of the processor 114 can be configured to receive the first set of image position data and the set of player position data from the projector tracking system 118. The game module 122 can further calculate the second set of image position data. In another embodiment, the projector tracking system 108 can be configured to calculate the second set of image position data.
The second set of image position data can also be generated or processed based on a game schema defined by the game module 122 and executed by the processor 114. The game schema can be stored in the computing device 104 (e.g., in the memory 116 or the disk 120). Alternatively, the game schema can be obtained (e.g., a download) or accessed via the portable device 110 or the network 112.
In one example, the game schema is modeled after a soccer game. For example, the images 218, 222 can be an image of soccer ball. The first vehicle occupant 210 and the second vehicle occupant 212 can “kick” the soccer ball with appropriate gestures in relation to the floor 220. In another example, the game schema is modeled after a toy car game. For example, the images 218, 222 can be a an image of a toy car that the first vehicle occupant 210 and the second vehicle occupant 212 control using gestures to “drive” the virtual car on the floor 220. One having ordinary skill in the art will realize that other game schemas known could be implemented with the system(s) and method(s) described herein.
At step 408, the method further includes projecting the images according to the second set of image position data on the game surface. The image projection mechanism 306 can be controlled to project images according to the second set of image position data. For example, the image module 128 can send a signal indicating the second set of image position data to projector tracking system 108 in order to control the output of one or both of the imaging devices 126, 130, and in particular, the image projection mechanisms associated with the imaging devices 126, 130.
In the illustrated embodiment shown in FIG. 2, the second set of position data is projected as virtual image 222 by the imaging devices 214 and 216. The virtual image 222 is based on the first set of position data (i.e., the original position of the image 218) and the set of player position data. In this example, one or both of the vehicle occupants 210, 212 performed an action or gesture, defined by the set of player position data, with the image 218, defined by the first set of position data, resulting in image 222, defined by the second set of position data.
One having ordinary skill in the art will realize from the systems and methods described herein, and in particular, the first and second imaging devices, in-vehicle gaming can become a total vehicle entertainment experience. It will be appreciated that various modifications of the above-disclosed and other features and functions, or alternatives or varieties thereof, may be desirably combined into many other different systems or applications. Also that various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
