Is Tony Stark home?</h1> <span> <strong>Speaker: </strong> <a href="../speakers/jorge_6343">Joaquim A Jorge</a> <span> – Lisboa, Portugal</span> </span><br/> <span> <strong>Topic(s): </strong> <a href="../topics/graphics-and-computer-aided-design">Graphics and Computer-Aided Design</a> </span> </div> <div class="row lecture__section"> <h2>Abstract</h2> Work on interactive tabletops and surfaces has focused mostly on two-dimensional issues, such as multi-finger gestures and tangible interaction. Interesting as it is however, this picture is missing several dimensions. I describe work on 2D and 3D semi-immersive environments and present novel on-and-above-the-surface techniques based on bi-manual models to take advantage of the continuous interaction space for creating and editing 3D models in stereoscopic environments. I will also discuss means to allow for more expressive interactions, including novel uses of sound and combining hand and finger tracking in the space above the table with multitouch gestures on its surface continuously. These combinations can provide alternative design environments and allow novel interaction modalities. </div> <div class="row lecture__section"> <h2>About this Lecture</h2> <span> <strong>Number of
