I put both design, research, and art projects here, also including references and notes. I am trying to use here as a thinking platform now. You also can brow my another web site: (https://sites.google.com/site/scottiehuang0107/). Here has more clear description for my works. Whereas, if you have any comments or interesting can contact to me. [scottie.c.c.huang@gmail.com; 886-911331196]
my project done at March, 2008 Even nowadays CAD applications contain high capacity modeling functions, but it still couldn't replace the traditional design media (such as paper sketching and model making), which could demonstrate the craft sense extended from our hand skills. Using traditional design media, designers are able to extend their bodily dynamic expression and reveal handicraft sense in design. Therefore, this research is to propose CAD applications can redound on designer's perspectives to providing the opportunities in expressing characteristics of fine art. Spatial sketch system (SS-System) demonstrates a new framework of applying hands in virtual modeling. SS-System solves the problems: 1) Unable to freely execute the spatial ideas; 2) Getting lost from the original design ideas, while manipulating computer-aided design. SS-System helps designers in presenting their ideas rapidly and creating various associations of design prototypes during the development. The nimbleness of hands helps designers in creating the sense of craft forms.
my project of 3D interact technique design done at April, 2008 Architecture and interior design is usually done through 2D drawings in smaller scale. The drawings are hard to be interpreted by general people. Therefore, extra design efforts are taken for the communication between the designer and their customer. In fact, the drawing in smaller scale is one kind of design method taught in traditional academy of architecture design in order to simulate the in-scale spatial design. The designer, who goes through the traditional learning process, will be capable of using 2D drawing for design thinking. Through learning and adapting to the method, the designer will be able to transform spatial ideas into spatial drawings in smaller scale. Unfortunately, the usage of miniature 2D drawings in design process always causes the loss of design details and misses the potential opportunities inspired by the real-world reality. In this circumstance, this research will be dedicated to the 1:1 augmented reality interior design system (1:1-ARIDS) which will help users to have their design in real-world environment. 1:1-ARIDS includes two wearable devices: laser-pointer for 3D input and VR-glasses for visual displays. The combination actually helps designers in modeling and seeing design outcomes in real-time. 1:1-ARIDS is trying to enhance the communications between the designers and proprietors. And it also helps designers in expressing their design ideas more clearly by involving users into the experiential design process.
A 3D user interface for integrating the use of tangible tools into conceptual modeling [summer, 2007] Conceptual modeling is an actively creative stage in a design process. Through hand modeling and manipulation of different kinds of modeling tool kits for specific materials, designers are able to generate forms. This article presents a tangible human-computer interface of a C-StressBall for form manipulation and a CBenchWhirler for visual control. They create a new way of interaction between the virtual world and the physical space. They are aimed to ease the operation in design process by using CAD.

1. Introduction 1.1. Conceptual modeling in architecture design • Tangible sense is help designer to express more creative ideas by the senses of solidness and transform the spatial ideas into design models. • CAD contains high capacity computing power. It can overcome the constraints of gravity and generate with higher degree of form. But, it in deed takes extra efforts in process planning rather than form generation. • Ubiquitous Computing pushes computers into background and leave only the valuable information opposed to user. • Tangible User Interface bridge the gap between virtual world and the physical environment.
1.2. Objective • Use TUI to redesign CAD’s operation in terms of HCI, fits in the early phase of design process. • Traditional modeling tool go through human civilization and evolved for a long time, user could have ease understand of characteristic through practicing the sense of touch. • Construct a working prototype which is suitable for a design environment. • Two physical tangible tools: C-StressBall and C-BenchWhirler are established to contact with the tangible’s features and the modeling behaviors in the COMOEN.
2. System Design 2.1. System outline• Traditional modeling tool go through human civilization and evolved for a long time to develop the detail functions in the model-shaping process. • Users could understand their characteristic easily through practicing the sense of touch. • Two physical tangible tools: C-StressBall and C-BenchWhirler are established to contact with the tangible’s features and the modeling behaviors in the COMOEN.
2.2. C-StressBall • The actual feeling from C-StressBall is the objects crowd out from hands. • C-StressBall hold with the fingers and extruding the substance for design. • It reflects the pressure level in creating different size of ink dots. • Following gesture location from COMOEN to display the outcome in virtual world. • The IR distance sensor inside in C-StressBall connect to microcontroller offer the sense of pressure level of touch.
2.3. C-BenchWhirler • It provides a way of revolving the turntable with hand, which can rotating the objects in the virtual environment. • Providing designer switches the forms with different angles intuitively while rotating the C-BenchWhirler. • C-BenchWhirler is a circular turntable to make fast and ease adjustments of view. The optics mouse has repacked into C-BenchWhirler under table to detect turning actions.
2.4. Image capturing system • Image capturing board is used for real time retrieving visual data from two CCD cameras. • By LED light on C-StressBall, Image recognition is used to track lighting in the space. • Two CCD camera are placed on the (x, y) plane and (y, z) plane separately in order to obtain actual position from C-StressBall.
2.5. Output to the Virtual Environment • In order to obtain the spatial coordinate and pressure information. A text file format is used to save (x, y, z) position and pressure strength from IRX board. • C++ language is used to program new functions in MAYA, so that it can use the information from the txt file to display 3D animation.
3. Design outcome • COMOEN only utilizing the “sphere” function reaches a good sense to present concept. • Strength of using touches succeed in impelling design detail more thoroughly. • In few minutes, designer achieve a proper model through the consideration of volume and size.
The process of implementation Use C-StressBall to Detect Different level from the pressure.
