We propose the use of <i>Hand-to-Face</i> input, a method to interact with head-worn displays (HWDs) that involves contact with the face. We explore Hand-to-Face interaction to find suitable techniques for common mobile tasks. We evaluate this form of interaction with document navigation tasks and examine its social acceptability. In a first study, users(More)
Information spaces are virtual workspaces that help us manage information by mapping it to the physical environment. This widely influential concept has been interpreted in a variety of forms, often in conjunction with mixed reality. We present Ethereal Planes, a design framework that ties together many existing variations of 2D information spaces. Ethereal(More)
Tabletop systems provide a versatile space for collaboration, yet, in many cases, are limited by the inability to differentiate the interactions of simultaneous users. We present See Me, See You, a lightweight approach for discriminating user touches on a vision-based tabletop. We contribute a valuable characterization of finger orientation distributions of(More)
As wearable computing goes mainstream, we must improve the state of interface design to keep users productive with natural-feeling interactions. We present the Personal Cockpit, a solution for mobile multitasking on head-worn displays. We appropriate empty space around the user to situate virtual windows for use with direct input. Through a design-space(More)
The growth of mobile and wearable technologies has made it often difficult to understand what people in our surroundings are doing with their technology. In this paper, we introduce the concept of candid interaction: techniques for providing awareness about our mobile and wearable device usage to others in the vicinity. We motivate and ground this(More)

(eds.), Distributed User Interfaces: Designing Interfaces for the Distributed Ecosystem, Human-Computer Interaction Series, DOI 10.1007/978-1-4471-2271-5_19, © Springer-Verlag London Limited 2011 Abstract We explore the diffi culties involved with tightly coupled collaborative work on mobile devices. Small screens and separate workspaces(More)
Applying visual analytics to large software systems can help users comprehend the wealth of information produced by source repository mining. One concept of interest is the co-evolution of test code with source code, or how source and test files develop together over time. For example, understanding how the testing pace compares to the development pace can(More)
Current wearable interfaces are designed to support short-duration tasks known as micro-interactions. To support productive interfaces for everyday analytic tasks, designers can leverage natural input methods such as direct manipulation and pointing. Such natural methods are now available in virtual, mobile environments thanks to miniature depth cameras(More)
The limited viewport size of mobile devices requires that users continuously acquire information that lies beyond the edge of the screen. Recent hardware solutions are capable of continually tracking a user's finger around the device. This has created new opportunities for interactive solutions, such as <i>direct off-screen pointing:</i> the ability to(More)
As wearable devices gain acceptance, we need to ask, What will user interfaces look like in a post-smartphone world? Will these future interfaces support sophisticated interactions in a mobile context? The authors draw from visual analytics concepts to address the growing need for individuals to manage information on personal devices. Spatial analytic(More)
