To add, Microsoft surface isn’t using FTIR. They’re using DI.

The technology we, and microsoft use for their multitouch displays is build on that of Jef Hans demo’s. I’m sure he’ll has some patents on some things.

Indeed, he filled in many patents about FTIR:

http://v3.espacenet.com/textdoc?DB=EPODOC&IDX=WO2008017077&F=0

and other multi-touch input devices:

But i find it rather strange that the patent document is in Japanese, or something alike and not in American English, because we’re speaking about international and european patents here. I’m not sure your source is thrust worthy.

The document I linked is available both in Japanese and American English (depending on the links you click you get on the US, European or Japanese version). The source should be OK, here you have the English version:

Multi-touch technology has been there quite for some time and some patents are filed on different ideas. Apple has filed a patent for Multi touch gesture dictionary too. FINGERWORKS, INC. had filed for many patents and had few products like iGesture, TouchStream etc. The company seems to have ceased its business for the reasons not known. Microsoft too has more than 5000 patents to its credit for various ideas. They are bound to make many more based in Microsoft Surface.

It is reported that the United States Patent Application by Microsoft bearing number 20070192550 citing “Adaptive Granularity Refinement In Detecting Potential Data Races” is said to be the patent for Microsoft Surface. But the same is not clear. Microsoft also files a patent application for ‘A display system and method for use in controlling movement of a virtual image version of a physical object is described’ against 20070188444, which probably would be useful for Microsoft Surface.

Apple’s United States Patent Application number 20060097991 dated May 11, 2006 for “Multipoint touchscreen” is for ‘A touch panel having a transparent capacitive sensing medium configured to detect multiple touches or near touches that occur at the same time and at distinct locations in the plane of the touch panel and to produce distinct signals representative of the location of the touches on the plane of the touch panel for each of the multiple touches is disclosed’. Another application 20060026521 from Apple, ‘Gestures for touch sensitive input devices’ is for ‘Methods and systems for processing touch inputs are disclosed. The invention in one respect includes reading data from a multipoint sensing device such as a multipoint touch screen where the data pertains to touch input with respect to the multipoint sensing device, and identifying at least one multipoint gesture based on the data from the multipoint sensing device.’

There is bound to be some excitement related to patents and Microsoft Surface.

The following are some applications for US patents on multi touch and similar technologies. (sorry going to work on formatting these...)

Does anyone know if the DI method is patented? I’m aware that the term DI is created here (by whitenoise?), but is the technique itself the subject of any patent?

On a related issue… let’s grant that there’s some multitouch patent that is valid. Sonix says anyone can build a multitouch table (implying: without being sued), which I agree. But what if a commercial organisation builds one for internal use? Or use it as a public showcase, like those by the nuigroup, citywall, HP D5 conference, and GM Greenbuild Show… ?

[Edit: found answers (sort of) to my questions at http://nuigroup.com/forums/viewthread/147/ ]

Check out: uspto link

Does this mean FTIR is now patented?

And this seems to cover DI: link

I believe this has been posted before.
It is an application, so it does not mean it is an approved patent.
DI is too generic, thats like patenting air.

If anyone knows of published material that covers the material of the patent application before the date of the application, it would probably be a good idea to post it

If Han’s patentapllication is approved I think he pretty much has got the use of FTIR for multi-touch sensing locked up.

Nevertheless it seems that a lot of people has been utilizing FTIR for touch-sensing already, which is also mention in the references in Han’s patent application, and therefore the patent might not be approved. We can only wait and see whether his patent is approved or not.

It could be interesting reading that PhD thesis he is mentioning. Is there anybody that could have time to contact him, and gain permission to publish it here?

In the PhD thesis published in 1991, it’s stated that a certain “Sensor Frame” uses a light source and performs optical detection of gestures, resulting in a “multi-finger touch screen”.

Isn’t this the prior art that we are all looking for?

And if you look at the bibliography, the Sensor Frame was in existence since December 1986, more than twenty years ago.

I extracted from the thesis the following design of the Sensor Frame:
?ACT=28&fid=17&aid=1077_kS4WIM1hRhMu4SxkUGZn
