## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a heat-mount display and, more particularly, to a head-mount display with exercise information displayed thereon.
2. Description of the Related Art
Among a multitude of head-mount displays in the market, one of them is Google GlassTM. The Google GlassTM can display images in front of users' eyes without requiring additional fixed or handheld display. Users can interact with the Google GlassTM through voice control to easily display various types of information, such as time, weather, schedule, electronic atlas and the like in daily life for users' references.
With reference to FIG. 9, a Google GlassTM includes a head-mount frame 70, an electronic device 80, and a camera 90. The head-mount frame 70 has two temples. The electronic device 80 and the camera 90 are mounted on one of the two temples. The electronic device 80 is connected to the camera 90. The head-mount frame 70 is hollow for reserving space for wiring, and has two earpieces for respectively fixing the Google GlassTM on the two earflaps of a user. One of the earpieces 71 has a rechargeable battery therein electrically connected to the electronic device 80 to supply an operating power to the electronic device 80. The electronic device 80 has multiple driving circuits and a mini-projector 81. The mini-projector 81 projects images onto a virtual display screen 82 through the driving circuits. The virtual display screen 82 is a translucent prism reflecting the images projected from the mini-projector 81 to the retina of the user wearing the Google GlassTM. Because the electronic device 80 is mounted on one temple of the head-mount frame 70, the virtual display screen 82 can be positioned in an upper half portion of the user's angle of view. When the user looks up, the images projected from the mini-projector 81 can be seen. When the user looks straight ahead, the user's view will not be interfered by the images on the virtual display screen 82.
Another pair of conventional eyeglasses capable of receiving and displaying external information includes a first housing, a second housing, and a frame. The first housing and the second housing are respectively mounted on two temples of the frame, and are electrically connected to each other. The first housing has a transducer and a receiver. The transducer serves to sense a moving state of a user wearing the eyeglasses. The receiver serves to receive information transmitted from external equipment, such as mobile phones, GPS device, and the like. The second housing has a magnifying lens serving to display a screen corresponding to the received information for users to view.
Despite the capabilities of performing navigation, searching for information, receiving emails, uploading images and the like through a network environment, and being portable, the foregoing Google GlassTM and eyeglasses are still bulky and rely too much on network environment, and are expensive and not cost-effective. To people fond of exercise, carrying a bulky and costly Google GlassTM without being able to freely stretch and exercise like cycling, running, climbing, hiking and the like becomes a burden during exercise. When there is no network environment at all or when the user is doing exercise in a mountain area, convenience brought forth by the Google GlassTM thus has no chance of using its might. Additionally, high cost of the mini-projector in the Google GlassTM further raises the threshold in presenting the Google GlassTM as a consumer electronic product.

The display screen 40 is mounted on the outer sidewall of the transparent body 30, is electrically connected to the display unit, and displays images that are viewable to the user through the inner sidewall of the transparent body 30. The magnifying lens 50 is mounted on the inner sidewall and serves to enlarge the exercise information taking the form of icons or text messages and displayed on the display screen 40. In the present embodiment, the transparent body 50 is made of a glass material or an acrylic material.
With reference to FIG. 2A, an embodiment of the transparent body 30 is a hollow and transparent case, and has a first fixing portion 31 and a second fixing portion 32. The first fixing portion 31 is formed on an inner side of the outer sidewall of the transparent body 30, and the second fixing portion 32 is formed on an inner side of the inner sidewall of the transparent body 30. The first fixing portion 31 and the second fixing portion 32 respectively match a surface of the display screen 40 contacting the first fixing portion 31 and a surface of the magnifying lens 50 contacting the second fixing portion 32. Hence, when the display screen 40 is joined to the first fixing portion 31 and the magnifying lens 50 is joined to the second fixing portion 32, the display screen 40 and the magnifying lens 50 are securely mounted inside the transparent body 30. In the present embodiment, the magnifying lens 30 is a biconvex magnifying lens.
With reference to FIG. 2B, another embodiment of the transparent body 30 is substantially the same as the foregoing embodiment except that the transparent body 30 is solid and a hollow space is formed inside the transparent body 30, is adjacent to the inner sidewall of the transparent body 30, and takes a form of a biconcave magnifying lens. As the hollow space has two concave surfaces on two respective opposite sides thereof, the hollow space has the same effect of enlarging images on the virtual screen as that done by the magnifying lens 30 in the foregoing embodiment.
The information box 20 can wirelessly receive or wirelessly detect multiple pieces of exercise information, such as moving speed, moving displacement, geographical location, temperature, heartbeat and the like of the user, and displays the multiple pieces of exercise information on the display screen 40 using icons or text messages. The magnifying lens 50 further enlarges the multiple pieces of information on the display screen 40 for the user to view upon exercising. To explain the information box 20 in detail, with reference to FIG. 3A, an embodiment of a head-mount display in accordance with the present invention is shown, and the substrate 21 inside the information box 20 further has a microcontroller unit (MCU) 23. The MCU 23 is electrically connected to the display unit 24 and the wireless receiving unit 29 on the substrate 21, receives multiple sensing signals respectively detected by multiple external sensors, transmits the sensing signals to the MCU 23, converts the multiple sensing signals into multiple pieces of exercise information in the form of icons and text messages to the display unit 24, and instructs the display unit 24 to drive the display screen 40. The display unit 24 may be a liquid crystal diode (LCD), a light-emitting diode (LED), or an organic LED (OLED) display unit. The display screen 40 may be an LCD display screen.
The wireless receiving unit 29 is further wirelessly connected to a wireless transmitting unit 29A to wirelessly receive exercise information wirelessly transmitted from the wireless transmitting unit 29A. The wireless transmitting unit 29A is connected to a temperature sensing unit 25, a motion sensing unit 26, a physiological data sensing unit 27, and a geographical location sensing unit 28. The temperature sensing unit 25 serves to sense an ambient temperature and a user's body temperature upon exercising. The motion sensing unit 26 serves to detect a moving speed or a moving displacement of the user upon exercising. The physiological data sensing unit 27 serves to sense a heartbeat rate or other physiological data of the user upon exercising. The geographical location sensing unit 28 serves to detect a location and an altitude where the user is positioned upon exercising. Thus, the multiple pieces of exercise information include the ambient temperature, the body temperature, the moving speed or displacement, heartbeat rate or other physiological data, and location and altitude of the user.
With reference to FIG. 3B, another embodiment of a head-mount display in accordance with the present invention is shown, and the present embodiment is substantially the same as the foregoing embodiment except that there are multiple wireless receiving units 29 directly receiving wireless signals transmitted from corresponding sensing units and the wireless transmitting unit 29A is no longer needed. The MCU 23 is connected to a wireless temperature receiving unit 25A, a wireless motion receiving unit 26A, a wireless physiological data receiving unit 27A, and a wireless geographical location receiving unit 28A. The wireless temperature receiving unit 25A serves to receive a signal indicative of an ambient temperature or a body temperature of the user upon exercising transmitted from a wireless temperature sensing and transmitting unit 251. The wireless motion receiving unit 26A serves to receive a signal indicative of a moving speed or a moving distance of the user upon exercising transmitted from a wireless motion sensing and transmitting unit 261. The wireless physiological data receiving unit 27A serves to receive a signal indicative of a heartbeat rate or other physiological data of the user upon exercising transmitted from a wireless physiological data sensing and transmitting unit 271. The wireless geographical location receiving unit 28A serves to receive a signal indicative of a location and an altitude of the user upon exercising transmitted from a wireless geographical location sensing and transmitting unit 281. The multiple wireless receiving units include, but are not limited to, the foregoing wireless temperature receiving unit 25A, wireless motion receiving unit 26A, wireless physiological data receiving unit 27A, and wireless geographical location receiving unit 28A. For practical implementation, the MCU 23 may be connected to one or more wireless receiving units. For example, the MCU 23 is only connected to the wireless geographical location receiving unit 28A, is connected to the wireless motion receiving unit 26A and the wireless physiological data receiving unit 27A, or is connected to the wireless temperature receiving unit 25A, the wireless physiological data receiving unit 27A, and the wireless geographical location receiving unit 28A.
From the foregoing description, the multiple pieces of exercise information of the user can be viewed from the display screen 40 through the magnifying lens 50. To explain a concept of forming a virtual image between the display screen 40 and the magnifying lens 50, with reference to FIG. 4, the magnifying lens 50 and the display screen 40 are placed in front of a user's eyes 60 with the magnifying lens 50 situated between the display screen 40 and the user's eyes 60. The magnifying lens 50 is spaced apart from the display screen 40 by a gap L. The display screen 40 displays an object 41. According to the imaging concept, light rays of the object 41 emitted from the display screen 40 respectively pass through the focal point and the optical center of the magnifying lens 50, and an enlarged virtual image of the object 41 appears behind the display screen 40. The magnifying lens 50 pertains to a converging magnifying lens.
With reference to FIG. 5, the imaging concept and operation of the present application are described as follows.

After the wireless sports watch 94 wirelessly receives the sensing signals wirelessly transmitted from the wireless heartbeat detector 92, the wireless pedometer 95, and the wireless foot motion sensor 96, the wireless sports watch 94 further wirelessly transmits the sensing signals indicative of exercise information of the user to the head-mount display worn on the head of the user.
With reference to FIG. 7A, the various sensing units include a wireless heartbeat detector 92, a wireless speed sensor 97, and a bike recorder 98. The bike recorder 98 is mounted on a handlebar of a bicycle. The wireless heartbeat detector 92 is mounted on the chest of the user. The wireless speed sensor 97 is mounted on a front fork/rear fork of a frame of the bicycle. During cycling, the bike recorder 98 wirelessly receives sensing signals wirelessly transmitted from the wireless heartbeat detector 92 and then wirelessly transmits the sensing signals to the head-mount display worn on the head of the user.
In addition to outdoor exercise, the head-mount display can be applied to indoor exercise equipment, such as a treadmill. With reference to FIG. 8, when the user is exercising on a treadmill, the information box 20 can simultaneously and wirelessly receive sensing signals wirelessly transmitted from various sensing units mounted on the user and sensing signals wirelessly transmitted from all sensing units mounted on the indoor exercise equipment. With reference to FIG. 8A, some of the various sensing units mounted on the indoor exercise equipment and the user include a treadmill 91, a wireless heartbeat detector 92, and a speed sensor 93. The wireless sports watch 94 is worn around the user's wrist. The wireless heartbeat detector 92 is mounted on the user's chest. The speed sensor 93 is mounted in the treadmill 91. The speed sensor 93 and the wireless heartbeat detector 92 respectively detect speed information of the treadmill 91 and the user's heartbeat rate information, and further transmit the speed information and the heartbeat information to the head-mount display for the user's reference. In collaboration with the exercise functions provided by the treadmill 91, the head-mount display can strengthen users' effect of exercise. Additionally, besides the convenience in demonstrating information, the information box can further enhance the display screen 40 in terms of the space utilization efficiency and the effect of recognizing information.
