Indoor Positioning

GPS technology is accurate to within meters and ineffective indoor. Is it possible to precisely locate a device (within centimeters) inside a building ? Maybe …

Augmented Environment

Integrate information system to real-world environment with augmented reality ! Holography is still science fiction. But today, devices can give the illusion of it. Foreseeing next-gen interfaces.

Natural user interaction with a virtual environment is another subject I was planning to focus on. Today touch screen or motion sensing devices bring us closer to information, making it tangible. However, display is still the same, two-dimensional screen captive. When the information comes on top of user perception, it seems logical to choose its [...]

After several attempts to detect gesture, relying on skin color, I tried object detection through the famous Viola & jones method. I used it as implemented in OpenCV library. The experiment was about detecting a gesture used to select some displayed item. Among every possible hand movement, the opposite figure seemed the most intuitive and [...]

Outdoor, in urban or wild environments, you may be served by Global Positionning System, however, Indoor equivalent is quite rare. Some are focused on WIFI signal, others on RFID, trying (badly) to prove themselves as precise as GPS. Seeking a centimeter-accurate solution within closed space actually turned into assault course. Initial Need My first augmented [...]

The general objective of the augmented environment project is to design architectural and software solution allowing anyone to setup an augmented reality persistent environment. By removing the traditional AR-marker constraint, and supplying wearable “glasses-like” display, the goal is to fit information systems in everyday life and scenes. Science fiction anticipates profusion of holograms or see-through [...]
