Investigating the Effects of Individual Cognitive Styles on Collaborative
Gameplay
- Abstract: Sultan A. Alharthi, George E. Raptis, Christina Katsini, Igor Dolgov, Lennart E. Nacke, Z O. Toups
  
  In multiplayer collaborative games, players need to coordinate their actions and synchronize their efforts effectively to succeed as a team; thus, individual differences can impact teamwork and gameplay. This article investigates the effects of cognitive styles on teams engaged in collaborative gaming activities. Fifty-four individuals took part in a mixed-methods user study; they were classified as field-dependent (FD) or independent (FI) based on a field-dependent–independent (FD-I) cognitive-style-elicitation instrument. Three groups of teams were formed, based on the cognitive style of each team member: FD-FD, FD-FI, and FI-FI. We examined collaborative gameplay in terms of team performance, cognitive load, communication, and player experience.

GAVIN: Gaze-Assisted Voice-Based Implicit Note-taking
- Abstract: Anam Ahmad Khan, Joshua Newn, Ryan M. Kelly, Namrata Srivastava, James Bailey, Eduardo Velloso
  
  Annotation is an effective reading strategy people often undertake while interacting with digital text. It involves highlighting pieces of text and making notes about them. Annotating while reading in a desktop environment is considered trivial but, in a mobile setting where people read while hand-holding devices, the task of highlighting and typing notes on a mobile display is challenging. In this article, we introduce GAVIN, a gaze-assisted voice note-taking application, which enables readers to seamlessly take voice notes on digital documents by implicitly anchoring them to text passages. We first conducted a contextual enquiry focusing on participants’ note-taking practices on digital documents.

Co-design Techniques for and with Children based on Physical Theatre
Practice to promote Embodied Awareness
- Abstract: Marie-Monique Schaper, Narcis Pares
  
  Research in Full-Body Interaction suggests the benefits of activities based on using embodied resources to strengthen the sensorimotor, cognitive and socio-emotional aspects of the user experience. However, scholars in this field have been often primarily concerned with the comprehension of and design for the user's mind. Little attention has been drawn on its connection to the bodily experience. The scarcity of adequate co-design methods with and for children to raise an awareness of their body during design risks of deriving interaction design decisions only from the perspective of adult designers. In this article, we present our research on novel co-design techniques to elicit children's embodied awareness.

Designing for Youth-Centered Moderation and Community Governance in
Minecraft
- Abstract: Katie Salen Tekinbaş, Krithika Jagannath, Ulrik Lyngs, Petr Slovák
  
  Online settings have been suggested as viable sites for youth to develop social, emotional, and technical skills that can positively shape their behavior online. However, little work has been done to understand how online governance structures might support (or hinder) such learning. Using mixed-methods research, we report findings from a 2-year, in-the-wild study of 8–13 year olds on a custom multiplayer Minecraft server. The two-part study focuses on the design of youth-centered models of community governance drawn from evidence-based offline practices in the prevention and learning sciences. Preliminary results point to a set of socio-technical design approaches shaping player behavior while also supporting youth interest in Minecraft-like online environments.

Do You Feel the Same? On the Robustness of Cued-Recall Debriefing for User
Experience Evaluation
- Abstract: Anders Bruun, Effie Lai-Chong Law, Thomas Dyhre Nielsen, Matthias Heintz
  
  Cued Recall Debriefing (CRD) is a form of retrospective think aloud approach. It involves re-immersing users to a level where emotional responses are comparable to those experienced during actual interaction with a system. To validate whether the robustness of CRD would vary with the time gap between the actual and recalled event and with the affective state preceding the recall, two empirical studies with altogether 100 participants were conducted. Specifically, participants’ emotions were measured in terms of galvanic skin response (GSR), heart rate (HR), and self-assessment manikin (SAM) rating when they were interacting with an email client seeded with usability problems.

Around-the-Head Tactile System for Supporting Micro Navigation of People
with Visual Impairments
- Abstract: Oliver Beren Kaul, Michael Rohs, Marc Mogalle, Benjamin Simon
  
  Tactile patterns are a means to convey navigation instructions to pedestrians and are especially helpful for people with visual impairments. This article presents a concept to provide precise micro-navigation instructions through a tactile around-the-head display. Our system presents four tactile patterns for fundamental navigation instructions in conjunction with continuous directional guidance. We followed an iterative, user-centric approach to design the patterns for the fundamental navigation instructions, combined them with a continuous directional guidance stimulus, and tested our system with 13 sighted (blindfolded) and 2 blind participants in an obstacle course, including stairs. We optimized the patterns and validated the final prototype with another five blind participants in a follow-up study.

PLIERS: A Process that Integrates User-Centered Methods into Programming
Language Design
- Abstract: Michael Coblenz, Gauri Kambhatla, Paulette Koronkevich, Jenna L. Wise, Celeste Barnaby, Joshua Sunshine, Jonathan Aldrich, Brad A. Myers
  
  Programming language design requires making many usability-related design decisions. However, existing HCI methods can be impractical to apply to programming languages: languages have high iteration costs, programmers require significant learning time, and user performance has high variance. To address these problems, we adapted both formative and summative HCI methods to make them more suitable for programming language design. We integrated these methods into a new process, PLIERS, for designing programming languages in a user-centered way. We assessed PLIERS by using it to design two new programming languages. Glacier extends Java to enable programmers to express immutability properties effectively and easily. Obsidian is a language for blockchains that includes verification of critical safety properties.
