Seeing Signs: On the appearance of manual movements in gestures

This dissertation presents the results of a series of studies on the appearance of manual movements in gestures. The main goal of this research is to increase our understanding of how humans perceive signs and other gestures. Generated insights from human perception may aid the development of technology for recognizing gestures and sign language...

Intelligent Design Objects (IDO): A cognitive approach for performance-based design

Design is complex. This is because it involves conflicting goals that are often vague. Also, prior to the design it is generally not clear how important goals are relative to each other. And finally the amount of possible solutions is large in general. These bottlenecks are addressed in this thesis. A novel approach for design is proposed, where...

Flat panel display characterization: a perceptual approach

Over the last decade, consumer television sets have substantially increased in screen size, with screen diagonals up to 65-inch and beyond. At the same time, their thickness has decreased to only a few centimeters.

Context dependent digital shape editing in product design

The present CAID systems insufficiently support designers with effective and intuitive tools for shape modelling. Designers' efficiency significantly decreases when shape alterations are performed. The research described in this thesis deals with the development of a methodology to support more effectively and efficiently the industrial...
