Introduction

Sidebar is a kind of widely used component for most window-based applications. A sidebar is defined as a container where application shortcuts are located. Currently, a sidebar is called out from hidden by pointing the cursor at a hot-area or a hot-edge. After calling out a sidebar, users can further point at a shortcut icon and click to trigger. In this project, such a conventional interaction model is replaced by a “Tangible Touch Slider” to increase the usability. The Tangible Touch Slider is a horizontal sensible area with lighting feedbacks on the C part of a laptop computer. By touching on this sensible area, the related sidebar on the screen will be called out; by sliding on it, user can switch among shortcut icons; by releasing from the sensible area, the selected shortcut will be triggered. After a preliminary test based on GOMS, this new interaction model can save up to 1.5 seconds especially when users are doing typing oriented works.

An Intuitive Tangible User Interface for Interactive Algorithmic Design

Introduction

The development of better User Interface (UI) and Tangible User Interface (TUI) for 3D modeling has lasted for decades. With the popularity of free form style achieved by algorithmic methods, the existing solutions of UI/TUI for CAD are gradually insufficient. Neglecting the steep learning curve of algorithmic design requiring solid background of mathematics and programming, the common drawback is the lack of interactivity. All actions rely heavily on mental translations and experimental trial and error. In this research, we try to realize the idea of interactive algorithmic design by developing a tangible calligraphic brush, with this device designer can intuitively adopt algorithmic methodology to achieve highly creative results.

Introduction

Storytelling is a very critical activity for children, either as a listener or a teller, in terms of development of narrative skills and realization of the world. Generally, by 3 years old, children are gradually skilled at labeling items and further realizing relations among them. These skills are rudiments for advanced storytelling activity later. Proper assistance and guidance including story books and caregivers are required for the precedent achievements.

For the goal of this research, we seek to provide a computationally enhanced tool to assist storytelling behavior. Specifically, we aim at assisting children’s behaviors of labeling and correlating before 3 years old which are critical abilities and moment for their future development. We develop a set of tangible cubes, named Storytelling Cubes (SC), which can physically represent underlying structure of story characters, actively monitor children’s behaviors/choices, continuously evaluate their progresses and dynamically modify based on their progress. SC is both an assistant tool for storytelling and an experimental instrument for studying children’s learning behavior.

Introduction

After studying 12 user’s behaviors of using a microwave oven through Contexual Inquiry Method, we finally figure out that a touch free interface is needed due to oily hands of users which always interrupt the cooking process. For clean and safty reasons, we create this touch free interface for users to test again. After comparing with previous ordinary microwave door, our touch free door does improve the usability of a microwave oven.

A Development of Multi Modal Communication Devices

Introduction

In our daily life, there are many subtle actions which can deliver our emotions in very unique ways especially those between acquaintances. From a glance, one can perceive not only the other’s existence but demands and feelings. Via a smile and a blink, one can deliver good intentions and concerns to the other. Even though there is no verbal or physical communication further needed, the communications still happen. These are what we defined as indirect emotional communications. However, when two people are not in the same space, these kinds of communications seem not to happen. TeleEGGs is a pair of devices we developed to solve this problem. In the other word, this device can assist long distance indirect emotional communication.
