INTERACTING with sketched interface designs

Abstract

Digital hand-drawn sketches provide a new and unique way of interacting with a prototype user interface design while it is still rendered as a sketch. The successful use of prototypes and scenarios for exploring design ideas is well documented. Hand-sketched designs have also been found preferable to formal diagrams during early design. The study reported here shows that interacting with digital sketches adds an exciting new dimension to the interface design process, we found that people do more revisions and more accurate revisions with digital sketches.

Multi-fidelity Prototyping of User Interfaces

“…The fidelity is said to be low if the prototype representation only partially evokes the final UI without representing it in full details. Between high-fidelity (hi-fi) and low-fidelity (low-fi) [17] exists medium-fidelity (me-fi) [9]. We usually observe that a UI prototype only involves one representation type, i.e.…”

Supporting Generic Sketching-Based Input of Diagrams in a Domain-Specific Visual Language Meta-Tool

“…Using hand-drawn designs in this way has the demonstrated advantages over conventional software diagramming tools of flexibility, encouragement of exploratory design, and support for collaborative annotation and design review [2,26,29]. Conventional diagramming tools have been shown by many studies to suffer from premature commitment to particular design artefacts and choices; over-constraint of user actions; high viscosity (making designs hard to change); stifling of creativity; and limited collaborative design and review support [29]. As many studies have shown, sketchingbased design tools for a wide range of diagram-centric tasks offer ways of combining the advantages of paperbased and whiteboard-based design with those of computer-based diagramming tools [2,5,7,11,15,20,29].…”

“…These include high-level requirements capture, system design, user interface design and code review [2,26,29]. A variety of increasingly popular hardware devices support sketch-based input to computer applications, including the Tablet PC, mobile PDAs, large-screen E-whiteboards, and plug-in tablets for conventional PCs and laptops.…”

“…A variety of increasingly popular hardware devices support sketch-based input to computer applications, including the Tablet PC, mobile PDAs, large-screen E-whiteboards, and plug-in tablets for conventional PCs and laptops. Much recent research in HCI and user interfaces has demonstrated the potential of such sketching-based user interfaces to enable more human-centric interaction with computers and to enhance the efficiency and effectiveness of user interfaces, particularly for early-phase design and during collaborative work [5,8,11,15,16,29].…”
