The limitations of graphical user interfaces have slowed the spread of computer usage to the entire population. Perceptual user interfaces are one approach that can overcome many of these limitations. Adding perceptual capabilities, such as speech, sketching, and vision, is the key to making interfaces more effective. We argue that informal user interfaces,(More)
People complete tasks more quickly when they have concrete plans. However, task lists place the burden of developing plans on the user. This paper investigates whether crowds can provide people with action plans. A between-subjects experiment found that people who received action plans from the crowd completed more tasks than a control group that did not.(More)
Accurately assessing the quality of one's work is a crucial skill for professional designers and design students alike. This paper describes teaching materials that help students self-assess their work in a design course at a large university in the US. Using these materials, students have been successful in evaluating themselves—in 69% of all weekly(More)
Understanding the Prediction Gap in Multi-hop Localization Wireless sensor networks consist of many tiny, wireless, battery-powered sensor nodes that enable the collection of sensor data from the physical world. A key requirement to interpreting this data is that we identify the locations of the nodes in space. To this end, many techniques are being(More)
In our previous studies into web design, we found that pens, paper, walls, and tables were often used for explaining, developing, and communicating ideas during the early phases of design. One practice was to produce information architectures using paper on walls. This practice inspired us to work towards The Designers' Outpost, a tangible user interface(More)
Remote support for physical tasks often takes a longer time and involves more mistakes than on-site support. The reason for this is that it is difficult for remote supporters to know what happened at the site and show how to operate briefly. In this paper, we propose a remote support system named <i>TeleTorchlight</i> that works between a tablet and a(More)
This work examines whether templates designed from principles of multimedia learning design, and learning sciences research, can support peer instruction in creating more effective educational content on the web. Initial results show that the structure and guidelines within these templates can help novices produce meaningful learning content while improving(More)
T WO CRITICAL GOALS for mobile devices seem intrinsically in conflict. For carrying, the smaller the better. Yet for interacting, more real estate is generally better. This tension makes for great sketch comedy: absurdly tiny phones that are impossible to interact with, or giant touch screens that are back-breaking to carry. Chris Harrison and colleagues(More)
The digitization of knowledge work has led to an increase in computer-related interruptions. Recovering from interruptions can get harder over time as knowledge about the suspended activity fades from memory. Prior research suggests that digital reinstatement systems should not only be concerned reminding users with previous content but also of their(More)
