292 SMArT ThINgS: UBIqUITOUS COMpUTINg USer experIeNCe DeSIgN some are hurt. The designer's responsibility is to empower more people than they hurt, within the limits of their ability. For example, Thackara (2005) argued that creating technologies that replace people without giving them something better to do is counterproductive. his position is that the world has more than enough people who need better jobs, so task elimination without corresponding job creation elsewhere has a net negative effect on society. 6 19.2.3 Explaining thE tEchnology Most people will learn about new technologies by using them. Their under- standing of the benefits, risks, and operation of a technology will be formed by their use of devices incorporating that technology. Many of these mental models -- possibly most (poole et al., 2008) -- will be inaccurate, exaggerat- ing benefits or dangers well beyond what is possible. For novel technologies or applications, it is the Ux designer's responsibility to educate and warn people as well as enable functionality. For example, groups in the UK are debating whether or not to include displays on smart electricity meters (Burns, 2009). These meters primarily relay usage information to the power company, but such displays would help the owners of the meters monitor electricity consumption as well as explain some of the underlying technology. Of course resources for doing analyses of a design's impact on the world may be very small, but the critical part is that it is done. It is simply the design- er's responsibility to identify potential negative impacts of a design and create designs that tend to minimize these impacts. The goal is not absolute knowl- edge of all possible negative impacts or perfect amelioration of any impact, but the choice of design details whose emergent properties tend to create more positive effects than if those details were not included. 19.3 WhaT's nexT?
