Abstract
A mobile device cover 1 with transparency and a tint or reflection layer on the side towards viewer is attached to the device 3 with a base unit 2. When opened, the cover reflects images 4 displaying on the screen of the device and creates a floating virtual image 6 looks like floating at the other side of the cover. For certain 3D graphics, the images may looks like a hologram. The cover may also reflect the viewers face to the camera for video conferencing and may include an additional light source to increase the brightness of the viewers face during such conference.

Floating image generating mobile device cover
This invention relates to a cover that is capable of generating floating virtual image for the videos and images displaying on the screen of a mobile device, e.g. a tablet or a phone.
Displaying a video or a static image with realistic 3D or hologram effects is not an easy task. To overcome this, the present invention proposes a cover with transparency that can reflect the displaying images on a mobile device to create virtual images with "floating" effects to make the images looks more realistic. For certain 3D graphics, the images may looks like a hologram.
When opened, it reflects videos or images from a mobile device with floating effects so that the viewer can enjoy more realistic video or 3D graphic images.
It uses a single light source directly from the device display; no extra light source is required to project the video or the images.
When opened, it can also reflect viewer's face to the front camera of the device, if there is any, for video conferencing.
Preferably, the cover can be added with a light source to increase the brightness of the viewer's face during the video conferencing.
Preferably, the cover should add a tint or reflection layer to the side that towards viewer to increase the brightness of the reflected images and also minimise the distortion, e.g. blur or double images.
Preferably, a stand can be used to position the device and cover to provide a better watching angle for the viewer.
Preferably, the cover has a base unit with that can be attached to the device.
Preferably, when not in use, the cover can be closed or removed from the device.
An example of the invention will now be described by referring to the accompanying drawings:
• figure 1 shows how the cover is attached to the device and generating a floating virtual image by reflecting a displaying image from the screen of the mobile device to the viewer;
• figure 2 shows the example of figure 1 in a different angle;
• figure 3 shows the example where the cover is used during video conferencing;
• figure 4 shows an additional light source added to the cover to increase the brightness of the user face during video conferencing;
• figure 5 shows the distortion of the projected image that results in a blurred image or double images;
• figure 6 shows a mean of minimising the distortion that is shown in figure 5;
2
• figure 7 shows a stand been used to adjust the device and the cover to a position that provides a better watching angle for the viewer; and
• figure 8 shows the cover in a closed position to protect the screen of the device it attached to.
A cover 1 with transparency has a base unit 2 that can be attached to a mobile device 3. The reflected light 5, by this cover, from the displaying image 4 on the mobile device reaches viewer's eye that creates a virtual image 6 looks like floating at the other side of the cover due to the transparency of the cover. For certain 3D images, it will look like a hologram with the floating effect. (Figure 1 and 2)
During video conferencing, the cover also reflects the light 7 from the viewer's face to the build in camera 8 of the device, so that the people on the other side of the video conferencing can see the viewer's face as the virtual image 9. A small light source 10 can be added to the cover to project light 11 on to the viewer's face during video conferencing. This increases the clarity of the image reflected to the camera by the cover. (Figure 3 and 4)
Since the cover is with transparency, the light from the displaying image can be reflected by both side of the surfaces of the cover as 5 and 12. This creates two virtual images 6 and 13 at the other side of the cover which cause a blurred image or double images. A possible, but not limited, method to overcome this is to apply a tint or reflection layer to the side of the cover that faces the viewer. This layer reflects part of the light 12 that goes into the viewer's eye into a different direction as 15 and reduces the brightness of the virtual image 13 so that the blur or double images effect can be minimised. (Figure 5 and 6)
A stand 16 can also be used with the cover to put the device into a position that the viewer can see the virtual image from a better angle and with more comfort. (Figure 7)
When not in use, the cover can be closed to protect the screen of the device. (Figure 8)

Claims (6)
1. A cover with transparency that reflects images displaying on the screen of a mobile device to generate floating virtual images on the other side.
2. A cover according to claim 1, which is applied with a tint or reflection layer to increase the clarity of the reflected image.
3. A cover according to claim 1 or 2, which can be used for video conferencing by reflecting the viewer's face to the camera and reflecting the displaying image to the viewer's eyes.
2. A cover according to 3, which is added with a light source to increase the brightness of the viewer's face.
4. A cover according to any of the preceding claims, which can be used with a stand under the device to adjust the device and the cover to a position that provides a better watching angle for the viewer.
5. A cover according to any of the preceding claims, which has a base unit that can be attached to the device.
6. A cover according to claim 5, which can be closed to protect the screen of the device it attached to.
