Pervasive Computing Support for Market Trading

在商业街购物体验之外，许多商品在市场上进行交易，在那里商品的安排和定价更加灵活，例如街头市场，农贸市场，汽车靴子销售，收藏家博览会和拍卖/两者都是实体的，从有组织的艺术活动，牲畜等到偶尔的活动和作为拍卖的市场摊位;以及虚拟的，例如eBay。很明显，普及计算技术对这些市场的组织和运作有很大的帮助：使用射频识别技术跟踪库存，提供电子目录;使用无线手持设备浏览和发现所需的物品;提供电子身份，这样就可以收集证据来建立声誉等等。目前还不太清楚如何设计这种技术，以便被接受和加强市场。我们的方法是对示范市场的运作进行详细的民族志研究，并在此基础上提出适当的理论和技术。任何市场交易的一个关键因素是信任的运作，我们相信，确保我们建立体现信任的技术是最有可能取得成功的途径。这种信任的体现将基于一个定义良好的理论模型，该模型可以进行分析，并且本身支持系统中的信任和信心，而不是特别的工程。普适计算环境在代表我们执行任务时，必须是值得信任的，并显示出值得信任。要想可信，底层软件必须有一个有效的人类信任模型，该模型基于构建信任的多种元素。为了证明自己值得信任，系统必须在人们建立信任的当前流程中工作，根据用户的参与程度向他们提供透明度和适当的反馈。

Outside the high-street shopping experience many goods are traded in market places where the arrangement andpricing of goods is rather more flexible, such as street markets, farmers' markets, car boot sales, collectors' fairs, andauctions / both physical, ranging from organised events for fine art, livestock etc. to occasional events and marketstalls operating as auctions; and virtual, such as eBay. It is obvious that pervasive computing technology has much tooffer the organisation and running of such markets: using RFIDs to track inventory, and offer electronic catalogues;the use of wireless handhelds to browse and discover desired objects; providing electronic identities, so that evidencecan be collected to build reputations and so on. It is less clear how such technology should be designed so as to beaccepted and enhance the market.Our approach is to undertake a detailed ethnographic study of the functioning of exemplar markets, and to createappropriate theories and technologies based on this understanding. A key factor in any market transaction is thefunctioning of trust, and we believe that ensuring that we build technology embodying trust is the most likely route tosuccess. This embodiment of trust will be based on a well-defined theoretical model, which submits to analysis, anditself supports trust and confidence in the system, over ad-hoc engineering. The pervasive computing environmentmust both be and show itself to be worthy of trust as it carries out tasks on our behalf. To be trustworthy, theunderlying software must have a valid model of human trust, based on the multiplicity of elements that go to constructtrust. To show itself worthy of trust, the systems must work within the current processes by which people constructtrust, providing transparency and appropriate feedback to the various users based on their level of engagement.
