For example, turning off most lights and lowering the thermostat in “Sleep mode”, or tuning settings and shutting down standby power in “Away” mode. These presets can be activated either by one button from any ALIS control interface (such as the mobile phone or embedded touch panel — Figure 2) or scheduled forpanel planned activation. For example, in a prototype currently under development, a smart alarm clock by ntrol the bed can wake both the resident and the house (byd one- right). putting the latter into Home mode). Note that these arere presented as examples: modes are entirely user configurable, and coexist with individual control settings for fine-grained control when desired. Controls differed slightly in North and West House(s). In North House, we added override controls for the Figure 3: The ALIS dashboard indicates daily usage statistics sophisticated internal and external automated shade and provides uncomplicated data visualizations for at-a-glance systems that tracked the sun, and extra state awareness of resource consumption.

IDENTIFYING TARGETS • Reduce flights - better communication? • Change your commute/ cut your mileage/ avoid congestion • Get an efficient small car next time or ride share • Cut food waste, seasonal food, food with low carbon miles • Go vegetarian, eat less meat • Simple efficiency measures (insulate, cut drafts, boiler, lightbulbs) - use energy more effectively, cut waste • Buy less, buy quality, by more locally, look after it, mend it, freecycle itThursday, 2 December 2010
  24. 24. MORE EFFICIENT BUSINESSES? • Online sales account for 10% of the total retail sales in the UK • 65 million online purchases (12%) weren’t delivered first time, with 2% failing to be delivered at all • £682 million of direct costs will be borne by consumers, retailers and carriers due to Internet shopping delivery inefficiencies (£1.26 per purchase) • Can we exploit delivery to one’s social network? • Can Ubicomp help us be more aware of the downstream impact of our choices and behaviours?Thursday, 2 December 2010
