This paper presents a platform in which interaction designers can effectively and rapidly develop tangible interactive prototypes by sketching. The study aims to build a platform that plays the role of sketching in the hardware-software integrated interactive product design process. The platform consists of three components: a sketch based interactive concept exploration software application called STCtools, a set of physical user interface(PUI) widgets with a key converter and a video projection based Augmented Reality desk (ARdesk). For prototyping, a designer creates hardware and software sketches with pen based computers using STCtools. Sketches of hardware and software are drawn in a client device and composed in an electronic whiteboard, which is the server device. PUI widgets can be physically attached on a foam mockup or on a screen of the client device. The hardware-software integrated simulations are conducted on ARdesk. The sketch simulation is captured and projected onto a paper marker created with invisible infra-red ink.
As everyday products become more intelligent and interactive, there are growing interests on the methods to improve emotional value attached to the products. This paper presents a basic method of using temporal and dynamic design elements, in particular physical movements, to improve the emotional value of products. To utilize physical movements in design, a relation framework between movement and emotion was developed as the first step of the research. In the framework, the movement representing emotion was structurized in terms of three properties; velocity, smoothness and openness. Based on this framework, a new interactive device, 'Emotion Palpus', was developed, and a user study was also conducted. The result of the research is expected to improve emotional user experience when used as a design method or directly applied to design practice as an interactive element of products.
During design reviews, multiple stakeholders convene to reflect on the quality of intermediate results and to decide upon following steps. As prior research indicates, such design reviews are only partly a structured, rational process; often aspects as trust, hidden agendas or lacking commissioning skills influence this activity. Furthermore, a wide range of media is being used during these meetings, which are difficult to recollect in their context after the event. This research project attempts to improve design reviews in the domain of Industrial Design Engineering by two means: (1) by providing a specific prototyping and annotation device employing physical mockups, (2) by recording both communication between stakeholders and interaction with the prototype to produce comprehensive coverage of the review session. Based on literature and additional case studies, an analysis of the information streams is presented. Furthermore, an Interactive Augmented Prototyping solution is devised. Early verifications show that the recording resolution still requires a lot of fine-tuning, which will be the primary focus prior to a comprehensive evaluation in practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
