“…For example, PerSketch, is a WYPIWYG (What You Perceive is What You Get) drawing system that allows perceptual interpretations of a digitally sketched shape to be specified and manipulated using simple pen-based gestures [19]. Similarly, the Back of an Envelope system is a drawing program that uses standard pattern recognition techniques to automate the recognition of emergent parts in a digital sketch [14]. Also, SD2 implements an approach based on a shape grammar formalism in which shape replacement rules are applied to identify and manipulate recognised parts of a shape [22].…”

“…They can act as an unobtrusive and natural interface that responds to the intentions of the designer, as exhibited by visual attention. Potentially, they can realise the ideal drawing editor tool which, in the words of Saund and Moran [14], "would be able to read the user's mind (his visual system in particular) and synchronize with whatever image entities the user happens to perceive as significant" (p. 175). In this way, eye tracking could substantially reduce the cognitive overhead needed for designers to interface with CAD systems and with design representations.…”

Throughout the history of CAD, a variety of interfaces have been employed with the aim of supporting designers' construction and manipulation of digital models. This paper explores the potential of eye tracking as a CAD interface, and presents a prototype that uses collected gaze data to support shape exploration in a two-dimensional vectorbased sketch editor. The eye tracking interface uses the visual interactions of users to identify interpretations of constructed shapes, according to recognised parts identified using methods from shape grammar research. It can therefore be argued that it supports construction and manipulation of shapes according to user intent. The prototype has been evaluated in a user study where design students carried out controlled shape exploration exercises which involved interpretation and manipulation of shapes. In the paper, key concepts of eye tracking methodology are introduced; the methods used to implement the eye tracking interface are described; and the user study and its outcomes are reported. The results are positive and indicate the potential for eye tracking as an interface for supporting shape exploration in CAD. Research Highlights• Explores the potential of eye tracking as an interface for computer aided-design• Describes methods for inferring user intent with respect to digital shape manipulation, based on gaze data • Presents a prototype eye tracking interface that supports dynamic shape interpretation in a vector-based sketch editor • Reports the outcomes of a user study that evaluates how successful the eye tracking interface is at inferring users' intent with respect to shape manipulation

“…This approach enables robust cutand-paste type operations. Saund et al [4] have introduced a perceptually-supported editing tool where they combine a variety of previously studied image editing methods [5,6] deployed in an interactive environment. In an earlier work [6], the authors studied decomposing simple images into geometric primitive based shapes for enabling simple shape based editing.…”

We present a new sketch-based product form exploration technique that works from images and sketches of existing products. At the heart of our approach, is a multi-stroke curve beautification method and a curve-based image deformation algorithm. The proposed approach converts groups of strokes into piecewise clothoid curves in order to produce visually pleasing shapes. The deformation diffusion algorithm then spatially distributes the user specified deformations through out the image to produce smooth transformations from the original image to the resulting image. We demonstrate the technique on a variety of images including photo-realistic images, real product images, and sketches.

“…Our work is dierent in that our intention is to extract emerging structure from free card layouts, whereas they intend to recover the structure of visual languages that was constructed based on a given grammar, which usually embody little ambiguity, and do not dier greatly among dierent users. Saund's perceptually supported sketch editor [15] is closer to our work|to allow users to access to the visually apparent structures in diagrams|although their target is pen-based sketches.…”

“…Ad-hoc extension of current clustering theories, such as mere extension of denition of`distance', would not be sucient to describe complex interactions between the links (described later). We rst emphasize that we want the parser to recognize \what the human visual system perceives" from diagrams [15]. The majority of existing visual processing algorithms discover hidden but concrete structures that exist in the real world, such as constructing 3D models in 3D-vision recognition.…”

Card-handling using hypertext editor can be a p owerful methodology for generation of ideas or understanding of complex problems. To support such activity, recognizing implicit structure in the arrangement of cards would be useful. But, because the structures to be r ecognized a r e by nature ambiguous and highly dependent on user-specic perception, it is dicult for conventional rule-based s p atial parsing algorithm to achieve this task. We propose techniques for building spatial parser suitable for nding such ambiguous structures based on the mechanics of human perception. Moreover, our parser is adaptively customized t o r eect a p articular user's preferences through an interactive suggestion process, supported by application of a genetic algorithm.
