iPad measures heart and breathing rates using only camera.

Philips Vital Signs Camera app measures fluctuations in skin colour and movement of shoulders to estimate your heart rate and breathing rate. It is impressive that skin colour can be tracked so accurately and quickly. Smartphone and tablet cameras are usually of poor quality (particularly forward facing cameras) so it is a testament to the algorithms that the system appears to work so well. See the review link below where they put it through some paces.

Integrate some of this technology into video conferencing and your tablet will be able to tell you when the person you are talking to is lying or not, or whether you’ve just embarrassed them. This would be useful to add to the extension of SixthSense that designer Timothy Byrne of Western Washington University is working on to provide social cues to suffers of autism.

SpeckleSense is a fast (1000 fps), precise (50 μm), low-cost (cheap components and no lenses) and compact motion sensor that exploits ‘Laser Speckle’.

Ever looked at a laser dot and seen a speckle pattern that seems to shift about as you move your head? That’s Laser Speckle. Researchers from Camera Culture Lab have exploited this by re-purposing the tracking sensor from an optical mouse to track the speckle pattern to sense motion in 3D, see the paper for more details. 

It’s compact and cheap which means you could have these built into mobile phones extremely cheaply, providing 3D mouse input control for mobile devices. 

It has similarities to Kinect technology, i.e. using an optical sensor to analyse a laser pattern project from a similar place. So Kinect on your phone might not be that far away.

I was reminded about Bokodes from Camera Culture Lab at an AR talk I gave recently. The system uses a 3mm microdot of tiled fiducial markers and a tiny lens that enables a portion of the markers to be read when the camera lens is focused on infinity.

Pros:

  • Encode a large amount of information into a tiny space
  • Pose information can be encoded into the matrix to assist augmented reality
  • Active and passive types
  • Do not have to be too close to the item in question

Cons

  • Two cameras required if you want to do AR
  • Non-trivial to create (unlike printed codes)
  • Decent optics required for zoom and wide aperture, maybe?

The current process looks too expensive to be used mass market but maybe a holographic implementation could be the way to exploit this phenomenon much cheaper (by mitmedialab)

[Update] It looks like a a similar technology has been developed in a collaboration between Max Planck Institute for Informatics and MIT Media Lab, Cambridge, Massachusetts a few years. By using an array of these lenses (each one presenting a pixel), hundreds of photos (same object, different views) are compressed into one that changes depending on viewpoint. Here is the article with a video example of a photo with shifting shadow.

Lucky bunny sleeps through first single-pixel wireless contact lens display prototype tests, bringing retinal AR one pixel closer to reality. The lens is wirelessly controlled over a distance of 2cm (when attached) and uses a Fresnel lens under the LED to focus the light on to the retina. This work was done by a team of researchers at the Parvis Research Group at the University of Washington. The New Scientist article has more information and the original paper is available as a PDF.

Visualised data-mining

Cabinet Education Infographic

Researchers for Information Is Beautiful has compiled an infographic for a Wired article that supports the stereotype that Tory governments are made up of public-school boys, whereas Labour governments are made up of grammar-school boys.

Information Is Beautiful really like visualising data and are currently running a contest with a new dataset. It would interesting to see some of these visualisations applied to ScraperWiki. ScraperWiki makes it easier to gather and structure wild data on the web.

Out Run. Out of the box

The Sega 80’s classic Out Run has had two cross-media implementations recently.

Out Run Analogic

Out Run Analogic is a tabletop analogue version based on the Arduino processor. Packing about as much processing power as the original implementation, you control a physical model over a rolling landscape. It is very similar to the wonderful Mobility Masterclass by Tim Hunkin at the Under The Pier Show in Southwold.

OutRun

OutRun by Garnet Hertzof has gone the other way and put the game into real streets. Image processing analyses the real street ahead and displayers it to the player as game graphics. Obviously, the penalty for crashing in the game has consequences in the real world. Although just for fun, this sort of stuff could be useful in an AR scenario where you would overlay non-visual information such a thermal imaging.

At the moment Garnet Hertzof is working on an augmented reality version doom where the virtual characters mimic the real player using a Kinect.

Immersive video puts you where the camera is.

A bit like still quicktime panoramic photos, the neat use of fish-eye lenses and iPad lets the viewer pan around as the film plays; not dissimilar to an on-rails 3D computer game. Looks like it would be most immersive when using the accelerometer to physically look around.

Clever use of the redundant space that is your laptop lid as a whiteboard for those coffee-table meetings. Kit available from http://thedrawtop.com/. Use your mobile’s camera and Evernote to capture important scribbles I think you’re onto a winning combination.

Interesting proof of concept for ubiquitous AR.

Obviously, we’re not going to be really using pizza boxes as laptops. That’s just silly. And I’m not sure about needing to kit every room out with the technology - I think the more personal approach that Pattie Maes et al are following with SixthSense has the potential for a more ubiquitous and personal augmentation of the world for users.

Nevertheless, some of the technology and concepts demonstrated here relating to supplementing real world objects with artificial affordances would go well with SixthSense.

Tesco are the first major supermarket in UK to trial AR so that customers can see how big products might be before ordering them. The web cam-based AR developed by KishinoAR works well for toys and items you can hold in your hands but I think furniture items like the TVs (fast forward to 1:35 in the video) are crying out for a mobile AR implementation so you can try them in their intended locations around the house.
