Yesterday I looked into (ab)using google maps to use with the MMA. Because I did not felt like implementing an entire tile engine myself I looked around on Google and found this actionscript project: Google Maps API opensource. However this [...]
MoreLast weekend I code a keyboard in actionscript and added it to the Multitouch Media Application. At this moment you will only be able to type text into the yellow square. Due some bug in touchlib/TUIO the shift button won’t [...]
MoreSince the start of my project, I wanted to do a multi-touch media application which could be used for organizing photos and videos. I started my first attempts with using the languages C++ and OpenGL. However this was more difficult [...]
MoreNot much new, just some minor bug fixes, improvements and compatibility fixes for the latest touchlib (rev. 61). Download: I’ve included a Windows binary and the source code of touch tracer for Linux users.By using the included Makefile you should [...]
MoreLast week Microsoft presented their implementation of a multi-touch screen. They decided to create it in the shape of a coffee table. Examples of applications can be found in the following video: More movies are available on the official page [...]
MoreIf you take a look at multitouch videos on Youtube, most of them are related to photo manipulation.These demo movies show the possibility of scaling, rotating and translating multiple photos at the same time. A few days ago I created [...]
MoreLast week I managed to get touchlib compiled under Ubuntu Linux (thanks Xvarg). While bug fixing and updating my touch tracer source code, I also tried to compile it in Ubuntu. Since I am not a linux guru, getting the [...]
MoreIt works! After the last blog not much had to be done about the FTIR screen. Actually I only used some tape to hide the wires on the sides. With all LED’s in place and the frame being placed on [...]
MoreIn this final step of building the FTIR prototype I will cover the soldering of LEDs. In my previous blog post I already calculated that 30 LED’s would be enough to cover the entire plate. As power source for my [...]
MoreInspired by other FTIR prototypes I decided to use an aluminum frame. The main reasons for are because its cheap and strong. Before actually working on the frame, I made a drawing in AutoCAD. Within this drawing I could easily [...]
MoreThe FTIR prototype which I am building will be using an acrylic plate which will be mounted in a frame. I tried to maintain the aspect ratio of a regular screen (4:3). The size of the plate is 41 x [...]
MoreFor the past several days, I have received parts for constructing my touchscreen prototype which is based on Frustrated Total Internal Reflection (FTIR). Today I will cover how the lens of the Philips webcam can be dismounted and replaced by [...]
MorePerhaps you noticed an article about multi-touch screen devices which I posted sometime ago. Inspired by the movies and publications of Jeff Han and Mitsubishi (Diamond touch table) I will be doing my master thesis research project on multi-touch gesture [...]
