quill: A Gesture Design Tool for Pen-based User Interfaces
نویسندگان
چکیده
Pen-based user interfaces are becoming more prevalent. Gestures are a powerful and convenient way to interact using a pen, but are difficult to design well. This paper describes the first intelligent gesture design tool, quill, which assists designers in creating and improving gestures for pen-based interfaces, both in terms of computer recognizability and likelihood of confusion among gestures by people. quill helps designers improve their gestures by warning them about potential problems with their gestures and offering advice about how to fix them. An evaluation with professional designers showed this type of advice to be promising, but requires care to implement well.

Dissertation Proposal: The Design and Evaluation of Gestures for Pen-Based User Interfaces
The topic of this dissertation proposal is methods for improving the design of gestures and gesture sets for pen-based user interfaces (PUIs) and interaction techniques for using gestures in PUIs. The ubiquity of pen/pencil and paper as a way of recording many types of data shows the promise of PUIs. A significant advantage of PUIs over paper is the ability to easily edit data. Editing commands...
متن کاملPDA and Gesture Use in Practice: Insights for Designers of Pen-based User Interfaces
Gestures are an essential element in the realization of paper-like user interfaces. Unfortunately, poor design and recognition of gestures has impeded the adoption of these interfaces. This paper describes a survey intended to illuminate the problems users have and benefits users enjoy with gesture-based user interfaces. From the results of the survey, we conclude that: users value gestures yet...

متن کاملHuman Computer Interaction Using Vision-Based Hand Gesture Recognition
With the rapid emergence of 3D applications and virtual environments in computer systems; the need for a new type of interaction device arises. This is because the traditional devices such as mouse, keyboard, and joystick become inefficient and cumbersome within these virtual environments. In other words, evolution of user interfaces shapes the change in the Human-Computer Interaction (HCI). In...
