DETAILED DESCRIPTION OF THE INVENTION

[0021] Smile triggered device (1) that reflects people's images only when they smile, smile triggered device (1) comprising: [0022] frame (2), [0023] mirror (3) having at least one reflecting surface and installed into frame (2), switchable material (4) which can be switched to transparent or opaque state and covered on the reflecting surface of mirror (3), [0024] camera (5) capturing images of the user, [0025] control unit (6) connected to camera (5) and adapted to processes facial expressions of the user in real time for detecting whether the user smile or not, wherein control unit (6) changing the state of switchable material (4) to the transparent state from opaque state by applying voltage thereto if a smile detected, [0026] at least one of battery (7) or a plug for powering camera (5) and control unit (6).

[0027] The inventive smile triggered device (1) is entertaining mirror (3) which allows people to see their reflections only when they smile. In the context of this invention, the user of the device is encouraged to smile to activate mirror (3) function. In the all embodiments of the invention described below, smile triggered device (1) essentially comprising; frame (2), mirror (3), switchable material (4), camera (5) and control unit (6). Camera (5) is disposed on frame (2) or behind mirror (3) and can be any type of digital camera (5) which produces digital images. Camera (5) is electrically connected to control unit (6). Control unit (6) is capable of processing images captured by camera (5) and can be any micro-controllers, for example; Arduino. Raspberry, Custom PCB or the like.

[0028] Mirror (3) has a polished or smooth surface (as of glass) that forms images by reflection on which switchable material (4) is coated. Switchable material (4) which is also called smart glass or switchable glass is a glass or glazing whose light transmission properties are altered when voltage, light or heat is applied. Switchable material (4) changes from translucent to transparent, changing from blocking some (or all) wavelengths of light to letting light pass through. Switchable material (4) includes one of custom LCD (liquid crystal display), electrochromic, photochromic, thermochromic, suspended particle, micro-blind or polymer dispersed liquid crystal devices.

[0029] Since smile triggered device (1) is electronic, it requires a power supply or access to electricity source. In the preferred embodiment of the invention, smile triggered device (1) comprising battery (7) for powering camera (5) and control unit (6). In another embodiment, a plug can be used instead of battery (7) for connecting smile triggered device (1) to an electrical socket.

[0030] To activate smile triggered device (1), the first step is turning on the device. In one embodiment, device (1) can be turned on by plugging into an electricity socket. In another embodiment, smile triggered device (1) includes a power button having an ON and OFF state and smile triggered device (1) can be turned on by switching the power button to ON position from OFF position. In another embodiment, smile triggered device (1) runs on standby mode and employs a motion detection sensor to track nearby movement, so that the motion detection sensor can switch smile triggered device (1) to on position when someone approaches.

[0031] Once smile triggered device (1) is energized and running, switchable material (4) is in non-reflective state. Non-reflective state can be a graphic, picture, drawing, shape, design, pattern, brand element such as logos or brand marks, words, solid colors or the natural color of the material. Non-reflective state can be fully non-reflective or slightly non-reflective, slightly reflective.

[0032] Smile triggered device (1) allows custom graphic applications on mirror (3) in two different embodiment, the first embodiment applies if switchable material (4) is a custom LCD, the second embodiment is if the smart glass is a PDLC. In the custom LCD embodiment, any type of custom 2D (two dimensional) graphic could be installed and showed on the LCD screen during the opaque state. In the PDLC embodiment the visual images, drawings or shapes could be printed, painted or sticked on the top of the reflecting surface of mirror (3) so that the visuals become visible when the PDLC becomes transparent. This feature allows placing brands, messages or images on smile triggered device (1).

[0033] After smile triggered device (1) is energized, camera (5) starts to capture image of the user. In one embodiment, the user is either prompted to smile by being shown a word (for example a written message that says smile smile to camera smile to see yourself etc), a shape (for example a visual illustration such as a smiley face) as described above or a light on the product, or by hearing a voice or sound (for example an audio message that is pre-recorded and played by an audio player (speaker)) that prompts to smile. Different voices or sounds can be stored in memory of control unit (6) or an external memory in smile triggered device (1).

[0034] When the user smiles, camera (5) captures the smile action from user's face and informs control unit (6). Once control unit (6) detects the smile input from camera (5), it changes the state of switchable material (4) from the first state to the second state by applying voltage to switchable material (4). The first state does not reflect the image, whereas the second state reflects the image. Since switchable material (4) is changed to transparent state, mirror (3) becomes visible and the user can see himself on the mirror.

[0035] In one embodiment, mirror (4) function is maintained until the user changes his facial expression. In other words, control unit (6) is keeping switchable material (4) in transparent states by applying continuous voltage to switchable material (4) until the user changes his facial expression. When the user changes his facial expression, camera (5) informs control unit (6). Control unit (6) processes the images coming from camera (5). If control unit (6) detects that the user doesn't smile, it stops applying voltage to switchable material (4) to change its state back to the nontransparent state. In another embodiment, mirror (4) function is maintained via control unit (6) by applying continuous voltage for a predetermined time (for a few seconds 0-10) after the smiling facial expression detected.
