Analyzing Information in Complex Collaborative Tasks
Zaad, L.J. ; Lenior, Dick ; Pool, E.M.C. van der ; Geest, Th.M. van der
2017, Article / Letter to editor (vol. 5, iss. Vol. 5, nr. 1, (2017), pp. 26-42)In this article, we present a method for analyzing the communication of people who exchange dynamic and complex information to come to a shared understanding of situations and of the actions planned and monitored by one party, but executed remotely by another. To examine this situation, we analyzed dispatchers working in police dispatch center in a large city in the Netherlands and their communication behavior in three different settings. The results of our analyses answer the question of how collaborative parties should assess an emergency situation in order to decide how to handle the incident in accordance with the procedures. Our results indicate which information must be communicated in order to deal with the current problem during the course of an incident. We will also demonstrate the proposed way of analyzing the communication used here is needed to understand how information is collaboratively handled in complex tasks.

Design Patterns for Mixed-Method Research in HCI
Holwerda, R.N.A. ; Bennis, Arthur ; Zaad, L.J. ; Bakker, R.R. ; Craenmehr, Sabine ; Hoppenbrouwers, S.J.B.A. ; Lenior, Dick ; Jacobs, M. ; Turnhout, K.G. van ; Niels, Ralph
2014, Article in monograph or in proceedings (NordiCHI'14)In this paper we discuss mixed-method research in HCI. We report on an empirical literature study of the NordiCHI 2012 proceedings which aimed to uncover and describe common mixed-method approaches, and to identify good practices for mixed-methods research in HCI. We present our results as mixed-method research design patterns, which can be used to design, discuss and evaluate mixed-method research. Three dominant patterns are identified and fully described and three additional pattern candidates are proposed. With our pattern descriptions we aim to lay a foundation for a more thoughtful application of, and a stronger discourse about, mixed-method approaches in HCI.
UX in the Wild: on Experience Blend & Embedded Media Design
Turnhout, K.G. van ; Leer, S. ; Ruis, Emiel ; Zaad, L.J. ; Bakker, R.R.
2012, Article in monograph or in proceedings (The Web and Beyond 2012)The internet is becoming a tightly interwoven part of our everyday lives. There is a growing market for web services which augment the daily life of users trough products with an internet connection. We call these real world extensions of the web embedded media. In the last couple of years we explored embedded media design through student projects with real world clients. We learned that the UX difficulty of embedded media design is to mix, enforce and augment existing user experiences. We’ve tried to capture this challenge in the intuitive notion of experience blend. In this paper we use examples from our project work to introduce this notion of experience blend.
ICT-ondersteuning voor communicatie in complexe werksituaties : Een taalkundige benadering
Zaad, L.J. ; Lenior, Dick ; Pool, E.M.C. van der
2011, Article in monograph or in proceedings (Chi Sparks)For successful execution of operational tasks within complex work situations, communication is essential. This ‘operational’ communication is analyzed to gain insight in the way the parties concerned put a similar meaning on the exchanged information. Or, as linguists call it: create shared understanding. This paper focuses on the characteristics of complex work situations, the methods of analyzing, and it indicates the preliminary results of the first field study. The final results consist of guidelines for the design of ICT-systems in order to realize a more effective and efficient way of communication.

The Influence of Control on the Acceptance of Ambient Intelligence by Elderly : an Explorative Study
Zaad, L.J.
2008, Article in monograph or in proceedings (AmI-08, pp. 58-74)This paper presents the results of a study on how elderly people perceive an intelligent system, embedded in their home, which should enable them to live independently longer. Users of a motion sensor system were interviewed about their experiences. A sensor system that autonomously works as well as a manipulated version was studied. The manipulation contained a touch screen that informed the users if the gathered information was correct before sending it to caregivers, so more control over personal information was provided. To test the use intention of the motion sensor system Spiekermann’s Ubiquitous Computing Acceptance Model of was used. This study shows that people, who perceive more control over their wellbeing, show more use intention. And that the subjective norm influences their acceptance. This study shows that acceptance models for Ambient Intelligence application in care situations need to be developed.
