However, complex goals such as design and engineering have remained stubbornly difficult to achieve with crowdsourcing workflows. Is this due to a lack of imagination, or a more fundamental limit? This paper explores this question through in-depth case studies of 22 workers across six workflow-based crowd teams, each pursuing a complex and interdependent web development goal. We used an inductive mixed method approach to analyze behavior trace data, chat logs, survey responses and work artifacts to understand how workers enacted and adapted the crowdsourcing workflows. Our results indicate that workflows served as useful coordination artifacts, but in many cases critically inhibited crowd workers from pursuing real-time adaptations to their work plans. However, the CSCW and organizational behavior literature argues that all sufficiently complex goals require open-ended adaptation. If complex work requires adaptation but traditional static crowdsourcing workflows can't support it, our results suggest that complex work may remain a fundamental limitation of workflow-based crowdsourcing infrastructures.","PeriodicalId":224409,"journal":{"name":"Proc.

Segura, Simone Diniz Junqueira Barbosa","doi":"10.1145/3095813","DOIUrl":"https://doi.org/10.1145/3095813","url":null,"abstract":"Visual analytics applications (VAApps) rely heavily on visual representations and notations to communicate information and support user interaction. The visual representations themselves are the main communication form used by designers, reflecting their interpretation of what data aspects should be highlighted and how users can explore the data. Ultimately, the combination of representation and interactivity guides the user's data analysis in VAApp. To keep the VAApp development centered in their users, the design team must pay special attention to the visual representations and their underlying interaction mechanisms. Our team is developing HistoryViewer, a VAApp itself for users to explore log data obtained from interactions with other (\"source\") VAApps (VAAppsrc). During the development of HistoryViewer and the instrumentation of a VAAppsrc, we noticed unanticipated benefits for the development of the VAAppsrc itself. This paper presents our HistoryViewer system, proposes an architecture for VAApps integrated with our log model, discussing some ancillary benefits of such instrumentation. Finally, it reports two empirical studies conducted to gather potential users' opinions about HistoryViewer, which revealed positive attitudes towards the system and pointed to opportunities for improvement.","PeriodicalId":224409,"journal":{"name":"Proc.

Forbrig","doi":"10.1145/3095809","DOIUrl":"https://doi.org/10.1145/3095809","url":null,"abstract":"In this paper, an extended version of task models is discussed that allows detailed specifications of cooperative activities. Within the presented specification CoTaL (Cooperative Task Language), there exist two complementary types of task models called role model and team model. One or more instances of each role model describe the specific activities of actors. The team model represents joined activities and reflects progression in cooperation between role instances. For each scenario there exists one instance of the team model. Preconditions and events can be assigned to tasks and refer to one or all running instances of a role model. An event can be a starting or finishing trigger and is activated as result of task executions. Additionally, variables can be defined. They are bound within the specified context during runtime and get the value of the identifier of a certain role instance. In this way, communication and collaboration between different actors can be specified. Tasks of a team model cannot be performed directly but present the result of the execution of other (role) models only. However, a team model can restrict the execution of role model instances.\u0000 It is shown how such models can be used to specify the activities in a smart meeting room. Snapshots of their simulation in CoTaSE (Cooperative Task Specification Environment) are presented. Additionally to the local implementation there exists an implementation in a cloud. It allows real cooperative executions of tasks.","PeriodicalId":224409,"journal":{"name":"Proc. ACM Hum. Comput.

In this article, a technology based on Genetic Programming is proposed to automate critical parts of the design process. In this approach, designers are supposed to define basic content elements and ways to combine them, which are then automatically composed and tested with real users by a genetic algorithm in order to find optimized compositions. Such a strategy enables the exploration of large design state-spaces in a systematic manner, hence going beyond traditional A/B testing approaches. In relation to similar techniques also based on genetic algorithms, this system has the advantage of being more general, providing the basis of an overall programmatic UI design workflow, and of calculating the fitness of solutions incrementally. To illustrate and evaluate the approach, an experiment based on the optimization of landing pages is provided. The empirical result obtained, though preliminary, is statistically significant and corroborates the hypothesis that the technique works.","PeriodicalId":224409,"journal":{"name":"Proc. ACM Hum.

Palanque, Miguel Pinto","doi":"10.1145/3095811","DOIUrl":"https://doi.org/10.1145/3095811","url":null,"abstract":"Ensuring that an interactive application allows users to perform their activities and reach their goals is critical to the overall usability of the interactive application. Indeed, the effectiveness factor of usability directly refers to this capability. Assessing effectiveness is a real challenge for usability testing as usability tests only cover a very limited number of tasks and activities. This paper proposes an approach towards automated testing of effectiveness of interactive applications. To this end we resort to two main elements: an exhaustive description of users' activities and goals using task models, and the generation of scenarios (from the task models) to be tested over the application. However, the number of scenarios can be very high (beyond the computing capabilities of machines) and we might end up testing multiple similar scenarios. In order to overcome these problems, we propose strategies based on task models manipulations (e.g., manipulating task nodes, operator nodes, information...) resulting in a more intelligent test case generation approach. For each strategy, we investigate its relevance (both in terms of test case generation and in terms of validity compared to the original task models) and we illustrate it with a small example. Finally, the proposed strategies are applied on a real-size case study demonstrating their relevance and validity to test interactive applications.","PeriodicalId":224409,"journal":{"name":"Proc.
