Culturally Enhanced Augmented Realities (CultAR) is a small or medium-scale focused research project (STREP) belonging to Seventh Framework Programme of European Commission (EU FP7). The main objective of CultAR is to develop an integrated mobile full mixed reality platform combining markerless augmented reality, mobile 3D maps, tactile interfaces and directional audio for advanced context-aware personalized and digital cultural experience in urban environments. Currently, I'm leading the WP7 regarding the integration of the different project components.
Revolution of Knowledge Work is funded by Tekes, as a large strategic opening. We create information-seeking and sense-making methods supporting a revolution of knowledge work. Our symbiotic human-information interfaces to heterogeneous data sources are context-aware user-controlled explanation-giving and interactive.By combining the potential of human creativity and the capability of computers to handle data, we support human cognition, freeing the knowledge worker’s time to sense-making, collaboration and creative thinking. Presently, I'm co-responsible by the research involving user input.
Find A Brand – Logo Detector
Automatic logo detector for Android applications using camera real-time detection. The goal of this project was to create a mobile application that can detect in real time a brand logo and launch an application related with the same brand. As a case-study the current prototype launches an image scratching app (“raspadinha”). The user has to aim at a physical brand and after the logo is detected the user has to scratch an image to see if there is some bonus beneath. I have worked in the user interaction for scratching an image.
Due the growth of video sharing, its manipulation is important, however still a hard task. In order to improve it, this work proposes a pen-based approach, called VideoInk. The concept exploits the painting metaphor, replacing digital ink with video frames. The method allows the user to paint video content in a canvas, which works as a two dimensional timeline. This approach includes transition effects and zoom features based on pen pressure. I have implemented a proof-of-concept prototype in C+ (openCV, openFrameworks and bbTablet) and running on Tablet PCs.
The CREATION-TOOL is an original video annotator that was designed and developed from scratch as a software output deriving from the TKB project. It supports multimodal annotation and is applied to contemporary dance as a creation tool. It was conceived and designed to assist the creative processes of choreographers, functioning as a digital notebook for personal annotations. The prototype, developed for Tablet PCs, allows video annotation in real-time, using a live video stream, or post-event, using a pre-recorded video stream. The tool also allows different video annotation modalities, such as annotation marks, text, audio, ink strokes and hyperlinks. In order to maintain the annotations context, i.e., to maintain the association between a note and the corresponding video feature, graphical video annotations can be combined with motion tracking algorithms. In addition, the system enables different modes of annotation and video visualization. The evaluation was made by international dance performers. I worked in the development, interaction design and evaluation of the Creation Tool.
mEmLearn (Winner of the HP Technology for Teaching Grant Initiative 2006)
The mEmLearn project departed from the VideoStore framework to support Tablet PCs. This project had the aim to define tools that enable students to augment the course materials in an interactive way, during or after the classes, to retrieve these materials at a later stage and to share them with other students or instructors. The system includes a Web drawing interface that allows students to annotate and share course materials with the Pen-based technology. I implemented the system prototype (Adobe Flash/Actionscript3) that enables pen-based video annotations, using Tablet PCs.
