课程大纲

第一周：图形用户界面
Graphical user interfaces turn computer control problem into visual problem solving. The lectures of this module introduce five attempts to enhance current GUI operations such as scrolling interfaces, management of desktop icons, pointing on a large display, digital inking, and vocal interaction.

第二周：二维图形与动画
In this module we will dive deep into the world of 2D. We will discuss techniques for authoring 2D drawings and animations. Specifically, we will introduce interactive diagram beautification, pen-and-ink texture synthesis, shape manipulation, and dynamic illustrations. We hope you will witness how interactive software can change burdensome drawing work into full of fun!

第三周：三维几何模型
In this module, we rise up from 2D plane to 3D space, and discuss 3D geometric modeling methods. Topics introduced are; suggestive interface for architectural models, a sketch-based modeling system for freeform shapes, a curve-based shape control method, a flower modeling system, and volumetric texture. You will see how 3D objects can be easily and quickly modeled by specially-designed 2D user interfaces!

第四周：变形与动画
Starting from this module, we are shifting our attention towards simulating/crafting real objects and movements, which usually require intricate systems to deal with. As for this module, we will introduce clothing manipulation techniques, layer operations for stacked deformable objects, spatial key framing for character animations, procedural deformation, and human motion visualization using stick figures. You will discover how deformation and animation techniques help visually reproduce complex objects and motions.

第五周：制作
In this module, we will discuss systems for supporting personal fabrication. In particular, we will introduce systems for designing plush toys,
beadworks, chairs, and softly folded objects. In addition, interactive packing method is presented.

第六周：计算机辅助设计
Nowadays, computers are indispensable for designing products; computers mediate the interaction between designers and products. But in most cases, designing and testing processes are separated, so that designers will not foresee the consequences of their design in real time. In this module, we will discuss computer-aided design supported by simultaneous physical simulation. The works introduced are: systems for designing cantilever, musical instruments, garments, furniture, and gliders. You will see how real-time feedback helps designers improve the output products!

第七周：与真实世界的交互
Computer-operated appliances, such as robotic cleaners, are gradually spreading to general households in recent years. These emerging technologies have opened the door to the new research area, i.e. research on the interactions between ordinary people and robots. In this module, we will discuss interactive techniques and systems for real world interaction. Topics include: a command card interface for robot control, style-by-demonstration for robot behavior design, an actuated puppet device for character posing, a painting interface for robotic lights, and a fur display.
