Make notes (and more...) on PDF's

I often need to review documents sent to me in PDF format. Since I own a Tablet-PC, not to take advantage of the calligraphic interface for that is not an option. For years I have used the Adobe Acrobat Professional v6.0 for that purpose. However, the version 6.0 was not clearly designed to be used with a pen and we have no license for newer versions (currently 9.0). Thus, I tried a few other tools and concluded that, in my opinion, the Grahl PDF Annotator is the best option to make notes on PDF documents.

T-b3DR online again

After a long down-time due to server problems, the Thesaurus-based 3D Object Retrieval (T-b3DR) webpage is again online. Among other stuff, you can find there some interisting utilities that were develepod during my PhD thesis (and after).

JLF Lab

I am currently involved in the "João Lourenço Fernandes" (JLF) Lab at IST Taguspark. In this lab are develop research on immersive and virtual reality, multimodal and new interaction paradigms, amongs some other topics. In the picture below you can see me wearing the Natural Point tracking suit (hat included), holding the SqueezyBall 6-DOF wireless interaction device and the e-Magin HMD glasses.

ACM MM 3DOR 2010

Last week I attended the International Workshop on 3D Object Retrieval, a co-event of ACM Multimedia 2010. This workshop brought together researchers from different fields, ranging from computer vision, computer graphics, machine learning and human-computer interaction, whose works relates to 3D object retrieval.

Although all work presented in this forum was relevant to my research, I was particularly interested in the paper "Local Visual Patch for 3D Shape Retrieval" by Mohamed Daoudi et.al. and the poster "A Benchmark for Best View Selection of 3D Objects" by Afzal Godil et.al.
