Tracking and gesture recognition system particularly suited to vehicular control applications

A system and method tracks the movements of a driver or passenger in a vehicle (ground, water, air, or other) and controls devices in accordance with position, motion, and / or body or hand gestures or movements. According to one embodiment, an operator or passenger uses the invention to control comfort or entertainment features such the heater, air conditioner, lights, mirror positions or the radio / CD player using hand gestures. An alternative embodiment facilitates the automatic adjustment of car seating restraints based on head position. Yet another embodiment is used to determine when to fire an airbag (and at what velocity or orientation) based on the position of a person in a vehicle seat. The invention may also be used to control systems outside of the vehicle. The on-board sensor system would be used to track the driver or passenger, but when the algorithms produce a command for a desired response, that response (or just position and gesture information) could be transmitted via various methods (wireless, light, whatever) to other systems outside the vehicle to control devices located outside the vehicle. For example, this would allow a person to use gestures inside the car to interact with a kiosk located outside of the car.

Vehicle control

A vehicle control system has a plurality of subsystem controllers including an engine management system 28, a transmission controller 30, a steering controller 48, a brakes controller 62 and a suspension controller 82. These subsystem controllers are each operable in a plurality of subsystem modes, and are all connected to a vehicle mode controller 98 which controls the modes of operation of each of the subsystem controllers so as to provide a number of driving modes for the vehicle. Each of the modes corresponds to a particular driving condition or set of driving conditions, and in each mode each of the functions is set to the function in mode most appropriate to those conditions.

Dynamic image processing method and device and medium

A motion image processing method and device for authenticating a user using a specific device, using motion information of an object. Time series monochrome images, obtained by photographing an object, using a camera, are input. An object is detected from an initial frame of the input time series images, using a basic shape characteristic, and a plurality of reference points to be tracked are automatically determined in the object. Then, corresponding points of the respective reference points are detected in an image frame other than the initial frame among the input time series images. Subsequently, motion information of a finger is calculated, based on the result of tracking the respective reference points and an assumption of limited motion in a 3D plane. Based on the calculated motion parameter, a solid object is subjected to coordinate conversion, and displayed if necessary. As a result of the tracking, a reference point in each frame is updated. Tracking, motion parameter calculation, and displaying are repeated with respect to subsequent frames.

Vehicular impact reactive system and method

System and method for reacting to an expected impact involving a vehicle including an anticipatory sensor system for determining that an impact involving the vehicle is about to occur prior to the impact and an impact responsive system coupled to the sensor system and actuated after its determination of the expected impact. The sensor system includes wave receivers spaced apart from one another, each receiving waves generated by, modified by, or reflected from a common object exterior of the vehicle. The impact responsive system attempts to reduce the potential harm resulting from the impact and can be a protection apparatus which protects a vehicular occupant or a pedestrian, such as one including an airbag and an inflator for inflating the airbag.

System to control daylight and artificial illumination and sun glare in a space

An illumination maintenance system for maintaining a desired illumination profile in a space throughout at least a portion of a day where the illumination sources include daylight and artificial light, the system comprising a first sensor for sensing an illumination level in at least a portion of the space, at least one window treatment for at least one opening for allowing daylight into the space, the window treatment selectively altering the amount of daylight entering the space, a plurality of electric lamps providing artificial light to supplement the daylight illumination of the space; the electric lamps being dimmable, a control system controlling the at least one window treatment and the plurality of electric lamps to maintain the desired illumination profile in the space, the control system controlling the plurality of electric lamps so that the dimming level of each lamp is adjusted to achieve the desired lighting profile and compensate for the daylight illumination in the space throughout at least the portion of the day; and the control system further operating to adjust the window treatment in the event of sun glare through the opening to reduce the sun glare and such that when the desired illumination profile within a defined tolerance is achieved, the control system stops varying the dimming levels of the lamps and the adjustment of the at least one window treatment.

Driver assistance system

A system and method of assisting a driver of a vehicle by providing driver and vehicle feedback control signals is disclosed. The system and method includes receiving location data of the vehicle from a GPS unit, receiving the location data of the vehicle and retrieving navigation characteristics relevant to the location data using a processing circuit, generating a most probable future path for the vehicle and determining a location of at least one navigation characteristic with respect to the most probable future path and the vehicle, generating vehicle data at least one vehicle sensor, and transmitting a control signal to a vehicle control area network to warn the driver of an upcoming navigation characteristic on the most probable path.

Protecting children and passengers with respect to a vehicle

There is provided a system and methods for mitigation of the potential dangers to which at least a child, and passengers, are exposed to prior to, during travel and after travel, when outside and adjacent a vehicle. Potential dangers to which a child is exposed are risks associated with driving and non-driving behavior of the driver, when the child is inside and outside the vehicle, when the vehicle is driven on public roads and on private property grounds, and as a result of deficient of mistaken operation of child and passenger related devices. The system and methods require input commands into an indicator to operate equipment elements aboard the vehicle, including sensors, operable devices and alert systems, and are operative for communication with remote stations, with adjacent-driven vehicles, and with the vehicle owner.
