Figure 1: Autostereoscopic technology allows 3D images popping out of the screen while natural interaction provides a seamless manipulation of 3D contents. AbstractA few years ago, the introduction of the WebGL API has allowed displaying 3D content in web browsers very efficiently by using the power of 3D accelerators. Nowadays, 3D web applications, from games to medical imaging, tend to compete with their desktop counterparts. Among the main factors that can improve the feeling of presence in terms of impressiveness, immersion and natural interaction play a prominent role in enhancing the quality of the user experience. Both immersion and natural interaction rely on dedicated hardware like 3D displays and tracking devices. Unfortunately, browser makers do not supply JavaScript mechanisms for accessing hardware for security reasons. In this paper, we propose a plugin-free solution using the new features of HTML5 (WebGL and WebSockets) in order to handle autostereoscopic displays and widespread tracking devices like IR depth sensors for providing immersion and natural interaction within the web browser.

Abdominal morphometric data acquisition using depth sensors.Abstract-The treatment of eating disorders is now part of the priority actions of the public health policy. For several years, nutritionists have been using tools relying on new digital technologies, able to provide new diagnostic elements. In this paper, we propose a complete methodology to acquire, analyse morphological data and establish typologies with low cost consumer electronics devices. We use a Microsoft R Kinect TM like peripheral to capture abdominal measurements. For each individual, we calculate two profiles in the sagittal and transverse planes respectively. The extracted quantitative information is then analyzed to build typologies of abdominal morphology.
