Microsoft 3D Holographic Display a Future Technology

Microsoft 3D Holographic Display a Future Technology

Wow a 3D Holographic Display?? Microsoft Research has conducted a laboratory scale demonstration of a 3D holographic display that can be viewed by multiple people from any angle and does not require the use of special eyeglasses. Unusually for Microsoft, the announcement and the accompanying video contain very few details of the technology or the planned end applications. From the sparse details seen on the video, the display appears to be based on the mirascope, which is a pair of convex mirrors bonded together with an opening at the top on one of them. Images of an object captured by laser photography are projected into the parabolic mirror cavity. With multiple reflections, the light beams get amplified and emerge from the hole to form a 3D hologram in air. This image can be viewed from any angle, you can poke a finger through it and so on. The only details disclosed by Microsoft is that 3000 images per second are projected at a speed of 15 frames per second. The holographic image, as seen from the video, appears small in size and in black and white.

The human eye sees objects by sensing the light reflected from it. The light reflected from different parts of the object vary and the two eyes perceive the reflected light slightly differently, to create a 3D image in the brain. The use of laser light beams on an object enhances differences in the light reflected. This reflection is recorded and played back to create holographic displays.

An early application of holographic displays has been in the advertising holograms used over the night sky at sports stadia and at entertainment venues such as rock concerts. Holographic advertising displays have also been built into point-of-sale terminals in shopping malls and placed in the lobbies of hotels and other public places. In these, the holographic image is projected on a glass or transparent plastic screen.

In recent years, the emergence of higher resolution cameras and faster computer chips has driven the search for higher definition 3D holographic displays. One of the leaders in this field is Zebra Imaging of Austin, Texas. Their ZScape technology was listed among Time magazine's 50 greatest inventions of 2011. The Zebra Imaging technology works with computer aided design software, with laser scan data and satellite images to capture thousands of "Hogel" ( Holographic image) points that are recorded on a film with a laser beam. When this film is viewed using a halogen or LED lamp, a 3D holographic image appears. This technology has been used at project construction sites to plan movement of lifting cranes, in medical imaging and in defense and security applications. Other products in this field include the RePro3D, from Tachi Labs of Japan.

The Microsoft 3D display technology appears to avoid this intermediate step of recording images on a film for playback by directly using computer images to create the holographic image. If the hologram is created as easily as the video clip suggests, it could drive costs down dramatically.

Possible future applications

Given Microsoft's domination of the office suite software, the possible applications of this new technology would be to create 3D moving images in presentations and other office documentation. It could also change the concept of video conferencing by replacing the 2D image of the participants, with a 3D virtual presence. This technology could quickly make its way into portable electronic devices such as music players, smart phones and tablets. Anyone listening to a piece of music may actually be able to project a holographic image of the singer or play the music CD as an image in air in front of him. This technology could also be deployed in the GPS devices used as map displays in cars to project a 3D virtual image of the route in place of a 2D map.

It would be fascinating to see what Microsoft and the others do with this technology in the coming few years.

Viewsonic TDi2340 Universal Display that could be a screen for Tablet or Phone

Viewsonic TDi2340 Universal Display that could be a screen for Tablet or Phone

Viewsonic TDi2340 was a universal display that could also works as the mobile monitor for your tablet or smartphone wirelessly. This cool universal monitor was a 23 inch monitor which claimed to be a suitable monitor for "cloud computing".

It's claimed as the suitable monitor for cloud computing because of the ARM11 processors plus Wi-Fi in it makes this monitor can display an image / video source originate from a tablet or mobile phone. Not just showing a picture / video just because the screen that there is also a touch screen which means that all the tasks that should be done in a tablet or mobile phone we can "move" to the screen this monitor. It's really a new technology for the mobile monitor that could also works as a touchscreen.

Although not described in detail but this monitor seems to be working without a computer (stand alone). Until now there's no information about when will Viewsonic TDi2340 Universal display available on the market and the price of this cool monitor. let's wait for a further information. If you need another cool mobile monitor then you should also check the monitor2go the next generation mobile monitor.

Lightpad G1 Transform your Smartphone into a Notebook

Lightpad G1 Transform your Smartphone into a Notebook

Is there a way to transform your smartphone into a notebook? well the answer is yes. now with the help of Lightpad G1 devices you could easily turn your smartphone into a notebook. LightPad G1 is an advanced projection accessory for your smartphones, which was displayed at CES 2012. Thanks to the pico projector technology, LightPad G1 can project contents of your phone on a large surface. Well, like a laptop dock for your tablet, you have this accessory for smartphones to watch contents on a large screen. It is actually a mounted QWERTY keyboard device. So there is no need to go for another keypad to prepare a document using your smartphone now

The LightPad G1 is also a highly energy efficient device. To project 500 nits of brightness, the accessory just consumes 2.5 watts of power. You can use a wall or any other surface to project images of up to 60-inch in size. The LightPad G1 is thin and it has a svelte form factor. You can certainly carry it around with less effort though weighing 400 grams.

Interestingly, the device supports all phones under iOS, Android, BlackBerry and Windows Phone platforms. The LightPad G1 offers a resolution of 854 x 480 pixels for projection on your wall. Meanwhile, next gen LightPad G2 can provide 1280 x 720 resolution pixels.

Thanks to the QWERTY keypad of the accessory, you can type a lengthy document using your smartphone. It means, using the LightPad G1, you cannot only watch films and surf through images, but also perform most activities you can do on a computer. Price details of the LightPad G1 are not available. It is not also clear when will the accessory will land in stores.

It seems that on the future there will be more cool technology that can morph your gadget into another gadget using the invoked computer technology. So if you want to transform your smartphone into a notebook then you have to wait for this Lightpad G1 devices.
