By its nature, the discipline of human computer interaction must take into consideration issues that are most pertinent to humans. We believe CHI community faces an unanswered challenge in creation interactive systems: sustainability. For example, climate scientists argue serious consequences change can be averted, but only if fundamental changes made. The goal this SIG is raise awareness these and start a conversation about possibilities responsibilities we have address

Traditionally, computer interfaces have been confined to conventional displays and focused activities. However, as become embedded throughout our environment daily lives, increasing numbers of them must operate on the periphery attention. <i>Peripheral displays</i> can allow a person be aware information while she is attending some other primary task or activity. We present Peripheral Displays Toolkit (PTK), toolkit that provides structured support for managing user attention in development...

What role can social networking Websites play in supporting large-scale group action and change? We are proposing to explore their use individual reduction personal energy consumption. In this we summarize some existing uses of on the Web propose an approach that integrates feedback about ecological footprint data into sites Internet portal sites. Integrating such popular, commonly used allows frequent performance, while enabling exploration motivational schemes leverage membership. compare...

Human routines are blueprints of behavior, which allow people to accomplish purposeful repetitive tasks at many levels, ranging from the structure their day how they drive through an intersection. People express actions that perform in particular situations triggered those actions. An ability model and understand likely occur could technology help improve bad habits, inexpert other suboptimal routines. However, existing routine models do not capture causal relationships between describe Our...

Industrial knitting machines can produce finely detailed, seamless, 3D surfaces quickly and without human intervention. However, the tools used to program them require detailed manipulation understanding of low-level operations. We present a compiler that automatically turn assemblies high-level shape primitives (tubes, sheets) into machine instructions. These allow knit objects be scheduled, scaled, otherwise shaped in ways thousands edits At core our is heuristic transfer planning...
