HCC-Small: Wristwatch Interfaces for Microinteractions

该项目将有助于开发新形式的移动人机交互，即“微交互”。 这些都是简短的交互，在某些情况下，几乎是在没有有意识的思考的情况下进行的，就像只需看一眼手表上的时间一样。 这种微交互已经成为移动计算和通信技术的主要用途：提醒约会、显示来电的主叫方 ID、记下电话号码或 URL、进行约会或接收简短的电子邮件。然而，很少有设备能够很好地支持微交互，从而导致功能的缺乏，并且微交互界面的设计指南也很少。这项研究将增加在这个新兴领域取得实质性进展所需的基础知识和设计原则。该研究将调查微交互的障碍，创建微交互界面的设计指南，创建一个支持基于手势的微交互技术的MAGIC（移动动作和手势界面控制）工具包，并生成和研究实例化研究结果的原型。该项目将专注于将手表作为社会可接受的、快速访问的交互平台。之前的研究表明，访问时间（检索设备并浏览其界面的时间）是导致“犹豫”或决定不使用界面的主要原因。该研究将量化访问时间对犹豫的影响，为典型微交互任务的适当访问时间制定设计指南，并通过量化手表的访问时间（与口袋或腰带等其他典型设备安装位置相比）来提供最小化犹豫的具体建议。 具体来说，将检查四种类型的微交互：扫视、计算机发起的事件、用户发起的事件以及一种新的交互方式“双重目的语音”，其中用户对话中的关键短语同时触发移动设备上的操作。该项目将创建基于手表的手势、触摸屏和语音系统原型，支持每种微交互类型。 这项工作将鼓励移动界面研究的新方向。 学生广泛参与该项目将使他们能够培养广泛的硬件和软件原型设计技能。

This project will contribute to the development of new forms of mobile human-computer interaction that can be called "microinteractions." These are short interactions that, in some cases, are performed almost without conscious thought, comparable to checking the time on a wristwatch by a mere glance. Such microinteractions are already major uses of mobile computing and communication technologies: being reminded of an appointment, displaying the caller ID of an incoming call, noting a phone number or URL, making an appointment, or receiving a short e-mail. Yet few devices support microinteractions well, leading to a lack of use of the functionality, and there exist few design guidelines for microinteraction interfaces. This research will increase the fundamental knowledge and the design principles required to achieve substantial advances in this emerging field.The research will investigate barriers to microinteractions, create design guidelines for microinteraction interfaces, create a MAGIC (Mobile Action and Gesture Interface Control) toolkit that enables gesture-based microinteraction techniques, and produce and study prototypes that instantiate the research results. The project will concentrate on the wristwatch as a socially acceptable, fast-to-access interaction platform. Previous work suggests that access time - the time to retrieve a device and navigate through its interface - is a major contributor to "balking," or deciding not to use an interface. The research will quantify the effects of access time on balking, create design guidelines on appropriate access times for typical microinteraction tasks, and give concrete suggestions for minimizing balking by quantifying access times for the wristwatch as compared to other typical device mounting locations such as the pocket or belt. Specifically, four types of microinteractions will be examined: glances, computer-initiated events, user-initiated events, and a new style of interaction, "dual purpose speech," where key phrases in the user's conversation simultaneously trigger actions on the mobile device. The project will create wristwatch-based gesture, touchscreen, and speech system prototypes that support each of the microinteraction types. This work will encourage new directions in mobile interface research. The extensive involvement of students in the project will allow them to develop a wide range of hardware and software prototyping skills.
