Tool Development in Support of Story-Planning for Design Pitching

Despite the values of stories for design communication have been greatly proposed by literature, in students’ practices there is usually no story or no complete story in their pitching. As what often been complained by the students that making stories takes effort and time, appropriate tools are promising to help. This paper presents an exploration of such kind of tools with the aim to support story-planning for design pitching. A tool called StoryPrea is introduced and a user test of this tool is reported. The results shown the positive role of the tool and also indicated the directions for design iteration in future work.

The platform supports architectural design and medical planning through the use of physical props for interaction with 2D and 3D data.

Why (not) Adopt Storytelling in Design?

While the benefits of storytelling have been argued extensively in literature, the willingness to adopt it in actual practice, especially in students’ design projects, has however been slow. The lack of empirical studies on actual adoption of storytelling calls for a deeper understanding of the considerations that influence design practitioners, especially design students, to adopt or reject storytelling in design. This paper presents an exploratory study that aimed to identify the main obstacles that design students raise against using storytelling in their design process, and to explore ways to address such obstacles. The results imply that the main underlying reasons for poor adoption are the lack of perceived usefulness and the lack of tools to support. Based on the experimental observations, an opportunity for enhancing students’ acceptance of storytelling is identified.

We describe the design and development of Smart Rehabilitation Garment (SRG) a wearable system designed to support posture correction. The SRG combines a number of inertial measurement units (IMUs), controlled by an Arduino processor. It provides feedback with vibration on the garment, audible alarm signals and visual instruction through a Bluetooth connected smartphone. We discuss the placement of sensing modules, the garment design, the feedback design and the integration of smart textiles and wearable electronics which aimed at achieving wearability and ease of use. We report on the system's accuracy as compared to optical tracker method.

The paper more specifically proposed a method to extract diverse perspectives (called views) from experimental data. The current paper provides three improvements of this existing method by: 1) showing that a little-known approach for clustering attributes, called VARCLUS, can be applied and extended to provide a more optimal algorithm, 2) showing how the VARCLUS method can be applied to perform both within- and across-subject analysis, and 3) providing access to the VARCLUS method by incorporating it in ILLMO, a user-friendly and freely available program for interactive statistics.
<title>Quality asessment of coded images using numerical category scaling</title>

The results of several subjective experiments illustrate that numerical category scaling techniques provide an efficient and valid way not only to obtain compression ratio versus quality curves that characterize coder performance over a broad range of compression ratios, but also to assess perceived image quality in a much smaller range (e.g. close to threshold level). Our first object is to discuss a number of simple techniques that can be used to assess perceived image quality. We show how to analyze data obtained from numerical category scaling experiments and how to set up such experiments. Second, we demonstrate that the results from a numerical scaling experiment depend on the specific nature of the subject's task in combination with the nature of the images to be judged. As results from subjective scaling experiments depend on many factors, we conclude that one should be very careful in selecting an appropriate assessment technique.

In the image coding application, we describe the relation with existing pyramid coders. A new coding scheme, based on local one-dimensional image approximations, is introduced. In the image analysis application, we describe the relation between the Hermite transform and existing line/edge detection schemes.
