We all have many things we intend to do each day towards long-term health and well-being - activities like exercise, eating vegetables, tooth flossing, taking medication, taking regular breaks from desk work. We call these tasks "Sisyphean" because we need to do them every day, just like the mythical Sisyphus, who had to push a stone to the top of a hill each day, only to have it roll down again. In this talk I will describe the core ideas for SALs, Simple, Specialised, Sisyphean, Situated and Ambient Loggers, show examples of several that we have built, explain their design rationale, implementation and results of field trials of their use. SALs are devices that people can situate in the place where they can serve as an ambient reminder to help them remember to do particular Sisyphean tasks, log them and track their daily progress. Simplicity is a core requirement for the interface so that a glance or peripheral view is enough to help people remember the tasks and the logging is very quick and easy. The talk will report experiences in tackling the design challenges for an unobtrusive but effective SAL interface as well as the architecture of the whole system, based on Personis, a personal, long-term user modelling system. I will also discuss a new view of the notion of ambience, both for situated and mobile devices. The key contributions of this work are for a new form of light-weight and situated device that helps people achieve their long term goals that demand daily Sisyphean tasks.
