I am a design researcher in the department of industrial design at KAIST, Republic of Korea. I received BSc, MSc, and PhD in industrial design from KAIST.

My research interest is developing new design prototyping tools to support prospective designers. The approach of development lies in integrating scientific knowledge and practical design skills to achieve usable systems. The main objective of my research is to build well-finished prototyping systems to deploy to the public, and derive robust observations and implications from actual usage in the wild. To conduct my previous studies, I was trained as designer-researcher having convergent thinking and skills for visual design, interaction design, system development, and evaluative study.

I have developed several prototyping tools for design scenario (MiniStudio, SketchStudio) and mechanism design (M.Sketch) for my PhD period. Now I am extending my viewpoint to find valuable prototyping system in design practice and education.

M.Gesture

An Acceleration-Based Gesture Authoring System on Multiple Handheld and Wearable Devices

 

Gesture-based interaction is still underutilized in the mobile context despite the large amount of attention it has been given. Using accelerometers that are widely available in mobile devices, we developed M.Gesture, a software system that supports accelerometer-based gesture authoring on single or multiple mobile devices. The development was based on a formative study that showed users’ preferences for subtle, simple motions and synchronized, multi-device gestures. M.Gesture adopts an acceleration data space and interface components based on mass-spring analogy and combines the strengths of both demonstration-based and declarative approaches. Also, gesture declaration is done by specifying a mass-spring trajectory with planes in the acceleration space. For iterative gesture modification, multi-level feedbacks are provided as well. The results of evaluative studies have shown good usability and higher recognition performance than that of dynamic time warping for simple gesture authoring. Later, we discuss the benefits of applying a physical metaphor and hybrid approach.
