New technologies and materials enable the physical form of display surfaces to become dynamic in terms of shape and movement. This enables devices to form a more intimate relationship with software data and the user’s environment. The research area of actuated interfaces aims at leveraging these qualities to enhance interaction with and representation of digital information, as well as creating...

Deformable models are segmentation techniques that adapt a curve with the goal of maximizing its overlap with the actual contour of an object of interest within an image. Such a process requires that an optimization framework be defined whose most critical issues include: choosing an optimization method which exhibits robustness with respect to noisy and highly-multimodal search spaces; selecti...
