These rules form a “program” that tells the computer what to do when future inputs arrive. Little research has explored how an end user can debug these programs when they make mistakes. We present our progress toward enabling end users to debug these learned programs via a Natural Programming methodology. We began with a formative study exploring how users ...

In this paper, we explore how to better support developers' collaboration in teamwork, focusing on the software implementation phase happening in the integrated development environment (IDE). Conducting a qualitative investigation, we learn that developers' teamwork needs mostly regard coordination, rather than concurrent work on the same (sub)task, and that developers successfully deal with scenarios considered problematic in literature, but they have problems dealing with breaking changes made by peers on the same project. We derive implications and recommendations. Based on one of the latter, we analyze the current IDE support for receiving code changes, finding that historical information is neither visible nor easily accessible. Consequently, we devise and qualitatively evaluate BELLEVUE, the design of an IDE extension to make received changes always visible and code history accessible in the editor.

We believe that these end-user programmers are not just coders but also designers, in that they interlace making design decisions with coding rather than treating them as two separate phases. To better understand and provide support for the programming and design needs of end users, we propose a design theory-based approach to look at end-user programming. Toward this end, we conducted a think-aloud study with ten end users creating a web mashup. By analyzing users' verbal and behavioral data using Schön's reflectionin-action design model and the notion of ideations from creativity literature, we discovered insights into end-user programmers' problem-solving attempts, successes, and obstacles, with accompanying implications for the design of end-user programming environments for mashups. The contribution of our work is three-fold: 1) the methodology of using a design lens to view programming, 2) evidence, through insights gained, of the usefulness of this approach, and 3) the implications themselves.

Consumers can better understand how to save electricity by gaining awareness of their consumption beyond the typical monthly bill. We conducted a study to understand consumers' awareness of energy consumption in the home and to determine their requirements for an interactive, always-on interface for exploring data to gain awareness of home energy consumption. In this paper, we describe a three-stage approach to supporting electricity conservation routines: raise awareness, inform complex changes, and maintain sustainable routines. We then present the findings from our study to support design implications for energy consumption feedback interfaces.

Designing such interfaces raises challenges and often requires multiple iterations. While we are generally prompt to discard more hard-to-use interfaces and smooth out usability issues, we want to raise here the issue of their potential benefits. We describe two cases in which we observed potential benefits from introducing barriers for collaborating and communicating with others. We attempt to shed a new light on interfaces with usability "problems" and how these problems may benefit system efficiency and user experience. We end with a discussion of the pros and cons of making systems harder for people to use, and how to integrate this perspective in the design process.

However, this strategy is often ineffective and cumbersome, especially when trying to study and compare several distant objects. We propose a new distortion technique that folds the intervening space to guarantee visibility of multiple focus regions. The folds themselves show contextual information and support unfolding and paging interactions. We conducted a study comparing the space-folding technique to existing approaches, and found that participants performed significantly better with the new technique. We also describe how to implement this distortion technique, and give an in-depth case study on how to apply it to the visualization of large-scale 1D time-series data.

Researchers are seeking better technological solutions, particularly improved support for aging at home. One common strategy involves monitoring of the elderly, either by medical staff or the elderly. We are pursuing a different approach: providing technology that makes it easier for the elderly to care for each other. This approach is derived from our interviews with recent widows who have created a tiny network of friends, each of whom takes responsible for checking on the others while remaining secure in the knowledge that the others will look out for them.

Where IT strategies are used to subdue the work-frame in which they were introduced, it now aims to complement the existing structure and ease the task of the workers. The design industry and particularly the architect industry is one of many that could benefit from development of this different kind of approach in computer system design.

When these learned programs are wrong, their users receive little explanation as to why, and even less freedom of expression to help the machine learn from its mistakes. In this paper, we develop and explore a set of candidate principles for providing salient debugging information to end users who would like to correct these programs. We informed the candidate principles through a formative study, built a ...

Although these learning systems are somewhat reliable, they are not perfectly accurate. Traditionally, end users who need to correct these learning systems can only provide more labeled training data. In this paper, we focus on incorporating new features suggested by the end user into machine learning systems. To investigate the effects of user-generated features ...

Technology probes are one of such techniques, developed recently to encourage users' engagement with design ideas while capturing interaction. In this paper, we describe a technology probe called Zebra, which aimed at exploring the design of an observation tool for fieldwork with busy professionals. We deployed Zebra in the coffee room of our lab and observed researchers' reactions to the proposed concepts it embodied, both as researchers and as participants. We found that participants engaged with the probe in ways ranging from playful performances, through to abandoning the social space. Based on analysis of the collected qualitative and quantitative data, we present our reflections on the Zebra probe, how it eased the burden of engagement in the design process, and helped us better understand the potential of the observation tool for participatory design with busy professionals.
