Multi-stage code examples present multiple versions of a program where each stage increases the overall complexity of the code. In order to acquire strategies of program construction using a new language or API, programmers consult multi-stage code examples in books, tutorials and online videos. Authoring multi-stage code examples is currently a tedious process, as it involves keeping several stages of code synchronized in the face of edits and error corrections. We document these difficulties with a formative study examining how programmers author multi-stage code examples. We then present an IDE extension that helps authors create multi-stage code examples by propagating changes (insertions, deletions and modifications) to multiple saved versions of their code. Our system adapts revision control algorithms to the specific task of evolving example code. An informal evaluation finds that taking snapshots of a program as it is being developed and editing these snapshots in hindsight help users in creating multi-stage code examples.

The form factor of mobile devices remains small while their computing power grows at an accelerated rate. Prior work has explored expanding the output space by leveraging free displays in the environment. However, existing solutions often do not scale. In this paper we discuss Open Project, an end-to-end framework that allows a user to "project" a native mobile application onto a display using a phone camera, leveraging interaction spaces ranging from a PC monitor to a public wall-sized display. Any display becomes projectable instantaneously by simply accessing the lightweight Open Project server via a web browser. By distributing computation load onto each projecting mobile device, our framework easily scales for hosting many projection sessions and devices simultaneously. Our performance experiments and user studies indicated that Open Project supported a variety of useful collaborative, sharing scenarios and performed reliably in diverse settings.

Effectively planning a large multi-track conference requires an understanding of the preferences and constraints of organizers, authors, and attendees. Traditionally, the onus of scheduling the program falls on a few dedicated organizers. Resolving conflicts becomes difficult due to the size and complexity of the schedule and the lack of insight into community members' needs and desires. Cobi presents an alternative approach to conference scheduling that engages the entire community in the planning process. Cobi comprises (a) communitysourcing applications that collect preferences, constraints, and affinity data from community members, and (b) a visual scheduling interface that combines communitysourced data and constraint-solving to enable organizers to make informed improvements to the schedule. This paper describes Cobi's scheduling tool and reports on a live deployment for planning CHI 2013, where organizers considered input from 645 authors and resolved 168 scheduling conflicts. Results show the value of integrating community input with an intelligent user interface to solve complex planning tasks.

We propose cutting as a novel paradigm for ad-hoc customization of printed electronic components. As a first instantiation, we contribute a printed capacitive multi-touch sensor, which can be cut by the end-user to modify its size and shape. This very direct manipulation allows the end-user to easily make real-world objects and surfaces touch-interactive, to augment physical prototypes and to enhance paper craft. We contribute a set of technical principles for the design of printable circuitry that makes the sensor more robust against cuts, damages and removed areas. This includes novel physical topologies and printed forward error correction. A technical evaluation compares different topologies and shows that the sensor remains functional when cut to a different shape.
