#ITS2011: Augmenting Touch Interaction Through Acoustic Sensing

Pedro Lopes, Ricardo Jota, Joaquim Jorge [Published at ACM ITS 2011, Kobe, Japan / paper] Recognizing how a person actually touches a surface has generated a strong interest within the interactive surfaces community.

Computer Vision – Tbeta first analysis…

Community Core Vision or CCV for short (also known as tbeta), is a open source/cross-platform solution for computer vision and machine sensing. It takes an video […]

Gesture Research #1 (multitouching…)

So I gather a collection of gestures (that later will turn into my pool of tests for users analyse user behaviour - prior to defining the gestures for my dj system) by means of observation of multiple systems and multitouch demos: a) Reactable (note: the reactable relies mainly on tangible objects, but parameter changes are done via […]

Some thougts on MT inspired by August de los Reyes (pt.2)

After the first few thoughs (pt.1 on the blog) we arrive at a new idea: Interacting with a table: what’s new on that? 1) So, first August brings out an important point (that of course is relevant to the Surface project) which is the nature of the “Table” element. First let’s recall that August is […]

Let’s give it a first try… (PureData and TUIO)

First Try of PureData and TUIO (homemade multitouch) from PedroLopes [turn up the volume because its very low] This is the document of my first 10 minutes of PureData alongside a really DIY multitouch table (done with a 16 fps camera, and absolutely no conditions!). It is simply a synth made with 2 oscilators that […]
