Proposed in the present invention is that, in a case in which a passenger of a vehicle wears a wearable device, to provide navigation to a destination, a path to the destination is divided into a walking course and a vehicle traveling course such that navigation for the vehicle traveling course is provided via a head unit of a vehicle and navigation for the walking course is provided via the wearable device. At this time, division of the walking course and the vehicle traveling course may be performed by the wearable device and may be performed by the head unit of the vehicle. In addition, bio-information of a driver acquired by the wearable device and monitoring information such as previously input profiles may be referenced upon division of the respective courses. For example, the bio-information may include an average step speed and health conditions (e.g., a heart rate and fatigue degree), and the profiles may include, for example, a desired exercise distance/calorie burn and preference for uphill road/stairs.
First, a description will be given of the configuration of an apparatus for carrying out the embodiments of the present invention.
FIG. 1 is a block diagram illustrating an exemplary configuration of a head unit of a vehicle according to an embodiment of the present invention.
Referring to FIG. 1, the head unit, designated by reference numeral 100, of the vehicle may include a wireless communication unit 110 connected to a wearable device such as smart glasses or a bracelet/watch type wearable device via wireless communication protocols such as, for example, Bluetooth or Wi-Fi, to exchange data including an audio-visual signal with the wearable device, a memory 120 storing map/destination data, a display unit 130 to visually output a map and navigation-related information, a sound output unit 140 to output a guide sound upon execution of a navigation function, a GPS module 150 to acquire current location information, and a controller 160 to control the above-described components. The controller 160 may perform judgment and calculation required to carry out the present embodiment. For example, the controller 160 may control the overall process of establishing a wireless data path with the wearable device. The controller 160 may judge an optimum path to a destination upon receiving destination information from the connected wearable device and control the display unit 130 and the sound output unit 140 to output travel information for the judged path. In addition, upon reception of monitoring information from the wearable device, the controller 160 may set a walking course and a vehicle traveling course to the final destination using the received monitoring information.
Meanwhile, the display unit 130 and the sound output unit 140 may be called an output unit for convenience.
FIG. 2 is a view illustrating an example of smart glasses applicable to embodiments of the present invention.
The smart glasses 200 are configured to be worn on the human head. To this end, the smart glasses 200 may include a frame unit (e.g., a case or housing). The frame unit may be formed of a flexible material for easy wearing. FIG. 2 illustrates the frame unit as including a first frame 201 and a second frame 202 formed of different materials.
The frame unit is supported by the head and internally defines a space for installation of various components. As illustrated, electronic components such as, for example, a control module 280 and a sound output module 252 may be mounted to the frame unit. In addition, a lens 203 to cover at least one of the left eye and the right eye may be separably coupled to the frame unit.
A display unit 251 may take the form of a head mounted display (HMD). The HMD is a display that is worn on the head of a user to display an image immediately in front of the user's eyes. To provide an image immediately in front of the user's eyes when the user wears the smart glasses 200, the display unit 251 may be located to correspond to at least one of the left eye and the right eye. FIG. 2 illustrates the display unit 251 as being located to correspond to the right eye so as to output an image toward the right eye of the user.
The display unit 251 may project an image to the user's eye using a prism. In addition, the prism may be a transparent to allow the user to view both the projected image and a general forward visual range (i.e. a viewing range through the user's eyes).
As described above, the image output through the display unit 251 may overlap a general driver's field of vision. Accordingly, the smart glasses 200 may provide navigation for a walking course based on augmented reality (AR).
A camera 221 is located proximate to at least one of the left eye and the right eye to capture a forward image. The camera 221 located proximate to the eye may acquire an image of a scene that the user views.
Although FIG. 2 illustrates the camera 221 as being incorporated in the control module 280, the position of the camera 221 is not limited thereto. The camera 221 may be installed to the frame unit and a plurality of cameras may be used to acquire a stereoscopic image.
The smart glasses 200 may include command input units 223a and 223b operated to receive a control command. The command input units 223a and 223b may be operated by touch or push action, for example.
The control module 280 is configured to control a variety of electronic components mounted to the smart glasses 200. For example, the control module 280 may allow establishment of a wireless data path with the head unit of the vehicle through a wireless communication unit (not shown) of the smart glasses 200, and transmit destination information or monitoring information through the established data path. In addition, upon reception of destination information from a smartphone, the control module 280 may set a walking course and a vehicle traveling course using the monitoring information and allow destination information of the set vehicle traveling course to be transmitted to the head unit of the vehicle. In addition, the control module 280 may control the sound output unit 252 and the display unit 251 to provide navigation for the walking course.
Meanwhile, vital signal sensors to monitor bio-information such as, for example, a body temperature and pulse, may be arranged at an inner surface of a distal end of the frame unit (i.e. legs of the glasses) coming into contact with the skin.
Although FIG. 2 illustrates the control module 280 as being installed to one side of the frame unit around the head, the position of the control module 280 is not limited thereto.
FIG. 3 is a view illustrating a bracelet/watch type wearable device applicable to embodiments of the present invention.
Referring to FIG. 3, the bracelet/watch type wearable device 300 may include vital signal sensors 341 and 342 affixed to an inner surface of a main body of the wearable device 300 coming into contact with the skin of a user, the vital signal sensor 341 being used to measure the body temperature and electrocardiogram (ECG) and the vital signal sensor 342 including an electrode for measurement of, for example, skin conductivity and electromyogram (EMG). In addition, a display unit 351 may be affixed to an outer surface of the main body to visually output the operational state of the wearable device 300, information acquired via the vital signal sensors 341 and 342, or navigation-related path information. Of course, the bracelet/watch type wearable device 300 may include, for example, a controller to control the aforementioned components and a wireless communication unit to exchange data with the head unit of the vehicle or a smartphone in a wireless manner, both the controller and the wireless communication unit being mounted in the main body.
A description will be given below of provision of a navigation function via interworking between the above-described head unit and a wearable device with reference to FIGS. 4 and 5.
FIG. 4 is a flowchart illustrating an exemplary process of providing navigation according to an embodiment of the present invention.
Referring to FIG. 4, a wearable device monitors the heath condition of the user periodically or based on an event (S410).
A smartphone may be wirelessly connected to the wearable device (S420A), and the wearable device may be wirelessly connected to the head unit of the vehicle (S420B).
When connection between the respective devices is completed, the user can retrieve a destination using the smartphone (S430). Destination retrieval using the smart phone is more convenient than that using the wearable device because the smartphone generally has a relatively large command input means such as, for example, a display unit and a touchscreen, which provides easier operation of the user. However, it is clear to those skilled in the art that this destination retrieval is given by way of example and destination retrieval may be performed using the wearable device.
When the destination is determined, retrieved destination information is transmitted to the wearable device (S440).
The wearable device sets a vehicle traveling course and a walking course using the transmitted destination information and monitoring information (i.e. profile information including, for example, the health condition and the propensity of exercise of the user)(S450). For example, when the user desires exercise and prefers stairs, the vehicle traveling course may be set to a short distance and the walking course may be set to include an uphill road or stairs. Even if the user desires exercise, the walking course may be set to a shorter distance (i.e. the vehicle traveling course may be set to a longer distance) upon determining that the user has a poor health condition at present.
After completion of the course setting, the wearable device transmits a location where the walking course begins, i.e. a destination of the vehicle traveling course to the head unit of the vehicle (S460).
The head unit of the vehicle provides a navigation function to the transmitted destination (S470). Then, when the vehicle reaches the destination, the head unit of the vehicle notifies the wearable device thereof (S480).
As a result, the wearable device provides navigation for the walking course to the final destination retrieved using the smartphone (S490).
The embodiment of FIG. 4 has been described as the final destination being retrieved using the smartphone and the wearable device setting the vehicle traveling course and the walking course. However, final destination retrieval and course setting may be performed by the head unit of the vehicle. This will be described below with reference to FIG. 5.
FIG. 5 is a flowchart view illustrating another exemplary process of providing navigation according to an embodiment of the present invention.
Referring to FIG. 5, a wearable device monitors the heath condition of the user periodically or based on an event (S510).
When the wearable device is wirelessly connected to the head unit (S520), the wearable device transmits acquired monitoring information to the head unit (S530).
When a destination is retrieved using the head unit (S540), the head unit sets a vehicle traveling course and a walking course using the received monitoring information (S550).
Thereafter, the head unit provides navigation to a beginning location of the set walking course (S560). Then, when the vehicle reaches the destination, the head unit of the vehicle notifies the wearable device thereof simultaneously with transmission of walking course destination information (i.e. information related to the retrieved final destination) (S570).
The wearable device may provide walking navigation to the corresponding destination upon receiving the walking course destination information (S580).
As is apparent from the above description, the following effects are acquired according to at least one embodiment of the present invention.
Upon provision of navigation to a destination, a walking course may be set in consideration of, for example, the propensity of exercise, health condition, and stamina of a person.
In addition, both a vehicle traveling course and a walking course may be conveniently set via single retrieval, and the accuracy of an estimated arrival time may be enhanced.
It will be appreciated by persons skilled in the art that the effects that can be achieved through the present invention are not limited to what has been particularly described hereinabove and other advantages of the present invention will be more clearly understood from the above detailed description.
The present invention as described above may be implemented as a computer readable code of a computer readable medium in which programs are recorded. The computer readable medium includes all kinds of recording devices in which data that may be read by a computer system is stored. Examples of the computer readable medium may include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, and an optical data storage device. In addition, the computer readable recording medium includes a carrier wave (e.g., data transmission over the Internet).
Accordingly, the above detailed description is not intended to be construed to limit the present invention in all aspects and be considered by way of example. The scope of the present invention should be determined by reasonable interpretation of the accompanying claims and all equivalent modifications made without departing from the present invention should be included in the following claims.
