最终用户启发研究是一种流行的设计方法。目前,此类研究通常仅限于实验室,限制了参与者的数量和多样性,从而限制了其结果的代表性。此外,此类研究结果的质量通常缺乏任何正式的评估手段。在本文中,我们通过创建 Crowdlicit 系统并引入最终用户识别研究(与启发研究相反)来解决启发研究的一些局限性。 Crowdlicit 是一个新的基于网络的系统,使研究人员能够进行在线和实验室内的启发和识别研究。我们使用 Crowdlicit 进行了一项基于 Morris 的“Web on the Wall”研究(2012 年)的众包启发研究,共有 78 名参与者,得出了一组符号,其中包括 6 个与 Morris 不同的新符号。我们通过开展众包识别研究评估了 49 个符号(43 个来自 Morris,6 个来自 Crowdlicit)的有效性。我们表明,Crowdlicit 启发研究产生了一组比莫里斯的更容易识别的符号。
End-user elicitation studies are a popular design method. Currently, such studies are usually confined to a lab, limiting the number and diversity of participants, and therefore the representativeness of their results. Furthermore, the quality of the results from such studies generally lacks any formal means of evaluation. In this paper, we address some of the limitations of elicitation studies through the creation of the Crowdlicit system along with the introduction of end-user identification studies, which are the reverse of elicitation studies. Crowdlicit is a new web-based system that enables researchers to conduct online and in-lab elicitation and identification studies. We used Crowdlicit to run a crowd-powered elicitation study based on Morris's "Web on the Wall" study (2012) with 78 participants, arriving at a set of symbols that included six new symbols different from Morris's. We evaluated the effectiveness of 49 symbols (43 from Morris and six from Crowdlicit) by conducting a crowd-powered identification study. We show that the Crowdlicit elicitation study resulted in a set of symbols that was significantly more identifiable than Morris's.
