1. Field of the Invention
The present invention relates to a wearable display device and more particularly, a wearable display device worn by a user in the form of glasses and displaying predetermined information for the user.
2. Discussion of the Related Art
Information technology (IT) including location based services making use of global positioning system (GPS) and indoor location technology; display technology; wireless communication technology; and so on provides the users with a host of benefits such as convenience of living.
Particularly, advancement of display technology has reached a point of commercialization of thin film type of flexible display and about 4 inch size of OLED flexible display has been recently developed.
Meanwhile, location technology enabling various kinds of location-based services in a smart-phone era has advanced to a point where accuracy of indoor location information relying on a base station or Wi-Fi is characterized in the range of tens to hundreds meters, in addition to outdoor localization by employing GPS signals.
In addition, wireless communication such as the fourth-generation mobile communication is now capable of servicing a large capacity video directly through a communication network while close-proximity wireless communication technology based on Wi-Fi is making N-screen technology widely distributed, which enables seamless connectivity between television and smart devices.
It is true that many people benefit from the advancement of IT but it is also true that there are people neglected including the visually impaired or hearing impaired, senior citizens, and the like who do not enjoy the benefits of IT.
People with low vision whose eyesight has been weakened due to innate or acquired impairments cannot watch television at the same position as normal people. Similarly in the case of reading a book, those people have to put a magnifying glass on the book and hold their eye close to the glass to see characters, having a difficulty in obtaining visual information as well as enjoying culture. Moreover, since those people cannot see the foreground scene clearly, their mobility is considerably restricted. Therefore new devices are being developed to improve eyesight of people with low vision based on cameras.
However, since those devices depend only on images captured through a camera, there is an apparent limitation for those people with low vision to live a life like normal people and as stated above, enjoying the full benefits from the advancement of IT is also not easy for those people.
The present invention has been made in an effort to provide a wearable display device enabling the visually impaired, hearing impaired, and the disabled to overcome the visual and aural barrier.
To solve the technical problems above, the present invention provides a wearable display device comprising a communication control module controlling transmission and reception of a signal; a signal processing module processing the signal input to the communication control module and extracting information from the signal; and a display module being worn by a user in the form of glasses and displaying the information.
The wearable display device further comprises a camera module being connected to the display module, capturing an image along the same direction as the sight of the user, and displaying the captured image on the display module.
The wearable display device further comprises a voice input module being connected to the communication control module and receiving a voice of the user and voices around the user.
The signal processing module processes a voice signal input to the voice input module and extracts the voice signal into the form of text, where the text is displayed on the display module.
The signal processing module of the wearable display device extracts voice from the signal and the wearable display device further comprises a voice output module being connected to the signal processing module and outputting voice extracted from the signal.
The wearable display device further comprises a navigation module being connected to the communication control module and receiving position information of the user and based on the information, providing route guide information for the user.
The navigation module comprises a position information receiving unit receiving position information of the user; a map controller storing a map and being connected to the communication control module and controlling the map according to a map control signal input by the user; and a direction indicating unit displaying a moving direction of the user on the display module according to the map control signal.
The navigation module further comprises a map view generation module being connected to the map controller and displaying the map on the display module by changing the view form of the map according to the map control signal.
The wearable display device further comprises a communication module being connected to the communication control module and transmitting and receiving the signal to and from an external device.
The communication module is one of wireless communication modules employing short range wireless communication including Wi-Fi and Bluetooth.
The communication module is one of wireless communication modules employing mobile communication technology including the third generation mobile communication and fourth generation mobile communication.
The wearable display device further comprises a TV receive module being connected to the communication control module and receiving a digital broadcasting signal.
The accompany drawings, which are included to provide a further understanding of this document and are incorporated on and constitute a part of this specification illustrate embodiments of this document and together with the description serve to explain the principles of this document.
With reference to
The communication control module 110 controls transmission and reception of at least one of a voice signal and an image signal.
