1. Field of the Invention
The present invention relates to wearable vehicle information indicators and methods of indicating vehicle information using the indicators and, more particularly, to wearable vehicle information indicators which are configured such that a driver who wears the indicator is capable of coordinating a variety of devices within a vehicle and is able to give operation commands to the coordinated devices, and methods of indicating vehicle information using the indicator.
2. Description of the Related Art
Generally, instrument clusters installed in front of a driver seat are used for providing a variety of vehicle information to drivers. In addition, different types of methods of enabling drivers to more easily and rapidly recognize a variety of information regarding the vehicle have been developed.
Recently, Google Glass, (which is a glasses-shaped smart device), has been introduced. Google Glass may be used to operate a variety of application programs in conjunction with a smart phone. Google Glass includes a headset shaped like a pair of glasses and includes a computer, an imaging device (i.e., a camera, video camera, etc.), a prism type display, a microphone, a speaker, a battery, etc. Furthermore, Google Glass has a five megapixel imaging device, a video function, an 802.11 b/g WiFi function, a Bluetooth function, etc. and is operated by voice or touch recognition methods. However, Google Glass has no function for coordinating different devices in one space. Furthermore, due to the display being disposed in front of the eyes of a user, when a user wears Google Glass when driving, images displayed may reduce driving attentiveness.
Accordingly, the present invention provides a wearable vehicle information indicator configured such that a driver who wears the indicator may coordinate a variety of devices within a vehicle, and may also provide operation commands to the coordinated devices while the indicator may periodically recognize the line-of-sight of the driver or determine whether motion of the driver matches a preset pattern. The present invention further provides a method of indicating vehicle information using the indicator and a computer program for the same.
In one aspect, the present invention provides a vehicle information indicator configured to be worn in front of the eyes of a user. The vehicle information indicator may include a coordinate setting module configured to set a space within a vehicle as a plurality of spatial coordinates, recognize a distance of a change in a line-of-sight movement of the user based on an eye zone as a reference point of the spatial coordinates, and set a particular zone from the spatial coordinates as detailed zone coordinates; a user command module configured to recognize one of a pattern of body motion of the user and frequencies that the motion is preformed or a direction and distance that the line-of-sight of the user moves, and communicate operation commands to at least one device within the vehicle; a wireless communication module configured to execute wireless communication between the user command module and the vehicle; and a battery configured to supplying power to the modules.
The coordinate setting module may include: a gyro- or acceleration sensor configured to sense a change in the line-of-sight of the user; an input module configured to input a point at which the line-of-sight movement of the user has stopped; and a controller configured to recognize the point input by the input module as a coordinate value. The input module may include one of a timer configured to measure a time for which the line-of-sight movement of the user has stopped and a touch pad configured to receive direct input of the point.
In another aspect, the present invention provides a method of indicating vehicle information using a vehicle information indicator, which may include: setting a particular spatial area in a vehicle as a plurality of spatial coordinates; recognizing, by a controller, a distance change in a line-of-sight movement of a user based on an eye zone which may be a reference point of the spatial coordinates of the indicator, and setting, by the controller, a particular zone from the spatial coordinates as detailed zone coordinates; transmitting, by the controller, an operation command signal of the user to a desired device of the vehicle via wireless communication when a direction and distance that the line-of-sight of the user has moved is matched with the desired device. The method may further include operating, by the controller, the desired device in response to the transmitted operation command signal.
The method may yet further include recognizing, by the controller, a pattern of body motion of the user and frequencies that the motion is performed (e.g., the number of times the body motion is performed) as a detailed operation command signal for the desired device while the desired device is operated; and selecting, by the controller, a menu item of the desired device in response to the detailed operation command signal. In addition, the method may include displaying, on a display within the vehicle, operation information regarding the desired device in response to transmission of the operation command signal of the user, to the desired device via wireless communication; and warning the driver, by a warning indicator executed by the controller, in response to the line-of-sight of the driver being out of the eye zone for a predetermined time.
Further, the method may include: analyzing, by the controller, a location of the eye zone of the indicator, a line-of-sight pattern for setting the coordinates, and the pattern of the body motion for the operation command, and identifying the user; transmitting a user identification signal to the vehicle; and automatically adjusting , by the controller, at least one of a position of a steering wheel, a position of a seat and a position of at least one side mirror in response to the user identification signal.
As described above, the present invention may have the following effects.
First, a user may obtain vehicle information with a glasses-type indicator, worn by the user, without space restriction. As needed, the user who wears the indicator may operate the vehicle. Since manipulation of a menu related to operating the vehicle using a sensor may be possible, the indicator may free both of the driver's hands while the driver is manipulating the menu, thus enhancing convenience of use.
Second, the indicator according to exemplary embodiments of the present invention may be worn on the face of the user and provide information to the user in response to variation of the line-of-sight of the user. Therefore, the present invention may reduce dangers which may result from manipulating vehicle controls, (e.g., switches or knobs), while driving, thus promoting safer driving. Furthermore, the indicator may rapidly provide vehicle information to the user, thereby reducing traffic accident risks.
Third, the indicator according to exemplary embodiments of the present invention may be in wireless communication with the vehicle, whereby devices (such as an imaging device, e.g., a camera, a video camera, etc., a display, etc.) of the vehicle may be used as the indicator without a need for a separate imaging device or display installed in the indicator. As a result, the weight of the indicator may be reduced, and the indicator may be manufactured at relatively low costs.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the attached drawings.
In the present invention an indicator may be worn as glasses and may be used to coordinate a variety of devices within a vehicle, and may be provided with operation commands for the coordinated devices. Accordingly, the indicator ma the configured to periodically recognize the line-of-sight of the driver or determine whether motion of the driver matches a preset pattern.
The indicator according to the present invention is a device which may have a similar shape to that of optical glasses or the like, however the invention is not limited only to devices having a glasses shaped structure, rather all types of structures are contemplated, so long as the user (driver) may be able to wear, remove and see through the device when the device is being worn.
The coordinate setting system 10 may be configured set the space within the vehicle as spatial coordinates. Furthermore, the coordinate setting system 10 may be configured to recognize a distance of a change in line-of-sight of a user based on an eye zone that is a reference point of the spatial coordinates, and set desired zones from the spatial coordinates as detailed zone coordinates. Accordingly, the coordinate setting system 10 may include a gyro- or acceleration sensor 12 which may be configured to sense a change in line-of-sight of the user (e.g., by sensing movement of the head of the user when the user's line-of-sight changes), an input module 14 which may be configured to input a point at which the line-of-sight movement of the user temporarily stops (e.g., for several seconds), and a controller 16 (e.g., an automotive microcontrol unit—MCU—) which may be configured to recognize the point, input in the input module 14, as one coordinate value.
According to exemplary embodiments, the input module 14 may use a timer which may be disposed within the indicator and may be configured to measure an amount of time for which the line-of-sight movement of the user is stopped. Furthermore, the input module 14 may include a switch or touch pad which may be provided on the leg portion of the indicator to enable the user to directly input the point.
Hereinafter, a method of indicating vehicle information using the indicator having the above-mentioned construction will be described.
The preset operation may include a spatial coordinate setting operation and an operation of setting detailed zone coordinates from the set spatial coordinates. The spatial coordinate setting operation, in which the user who wears the indicator may coordinate a particular spatial area within the vehicle, may be conducted first. For example, as shown in
Subsequently, in the operation of setting detailed zone coordinates, particular zones of No. 1 to No. N in the spatial coordinates may be set as detailed zone coordinates to determine a distance of a change in line-of-sight of the user, based on the eye zone as the reference point of the spatial coordinates. For example, as shown in
After the preset operation is completed, (e.g., in the above-described way), the indicator worn on the user may become ready to be operated. In particular, to operate various devices recognized as the detailed zone coordinates in the spatial coordinates, the user command system 20 in the indicator may be configured to recognize the direction and distance that the line-of-sight of the user has moved. When the direction and distance that the line-of-sight of the user moves are matched with a specific device in the detailed zone coordinates, an operation command signal of the user may be transmitted to a corresponding, specific device via wireless communication. Then, the specific device may be operated by a transmitted operation command signal.
While the specific device is operated, a pattern of body motion and the number of times of motion (e.g., the motion of turning the head up, down, left and right and the number of times the user performs a turning motion) may be recognized as detailed operation command signals for the specific device. Accordingly, the operation menu items of the specific device may be selectively conducted by the detailed operation command signals. Furthermore, when an operation command signal of the user is transmitted to a specific device of the vehicle via wireless communication and the specific device is thus operated by the operation command signal, operation information of the specific device may be simultaneously displayed on a display within the vehicle by the AVN controller. Accordingly, the driver may operate a desired device without separately manipulating the desired device with his or her hands. As a result, driving stability may be enhanced.
Hereinafter, several exemplary embodiments of the method of indicating vehicle information using the vehicle information indicator according to the exemplary embodiments of the present invention will be described.
