Indian users are the second largest population enrolled in MOOCs; yet little is known about them. In this qualitative study of MOOC users in India, the authors aim to understand how and why they use MOOCs. The findings show how MOOCs fit into the Indian context, specifically how they compare to the interviewees' educational experiences and the trade-off between language and content. This article also examines a group of ex-users, that is, a group of previous users who have turned away from MOOCs despite having an educational need. Furthermore, it highlights how the findings contribute to the debate on MOOCs and the promise for better education. Proponents of MOOCs have claimed that they are an improving force for education because they provide free access for anyone with an internet connection to high-quality teachers and materials on a scale not possible before. The authors use the emergent themes from the data to challenge these claims.

Part 5: Personalisation and Visualisation; International audience; We introduce the grab 'n' drop toolglass, an extension of the toolglass bi-manual interaction technique. It enables users to create and configure their own toolglasses from existing user interfaces that were not designed for toolglasses. Users compose their own toolglass interactions at runtime from an application's user interface elements, bringing interaction closer to the objects of interest in a workspace. Through a proof-of-concept implementation for Mac OS X, we show how grab 'n' drop capabilities could be added to existing applications at the toolkit level, without modifying application source code or UI design. Finally, we evaluate the power and flexibility of this approach by applying it to a variety of applications. We further identify limitations and risks associated with this approach and propose changes to existing toolkits to foster such user-reconfigurable interaction.

Part 5: Case Studies; International audience; This work discusses the affordances of the textbook in current classroom scenarios, and identifies the need to design learning media that support dynamism and enaction, specifically in science education. We illustrate this by a learning tool we’ve developed - Vector canvas, an AR based application linked with the textbook and the curricula. This is a work in progress attempting to observe and articulate changes in learning practice brought by introducing mixed media.

This paper describes our research investigating the perception of difficulty in video games, defined as players’ estimation of their chances of failure. We discuss our approach as it relates to psychophysical studies of subjective difficulty and to cognitive psychology research into the overconfidence effect. The starting point for our study was the assumption that the strong motivational pull of video games may lead players to become overconfident, and thereby underestimate their chances of failure. We design and implement a method for an experiment using three games, each representing a different type of difficulty, wherein players bet on their capacity to succeed. Our results confirm the existence of a gap between players’ actual and self-evaluated chances of failure. Specifically, players seem to underestimate high levels of difficulty. The results do not show any influence on difficulty underestimation from the players gender, feelings of self-efficacy, risk aversion or gaming habits.

Part 1: Adaptive Design and Mobile Applications; International audience; As new technologies emerge, so do new ways of interacting with the digital domain. In this paper, the touch interaction paradigm is challenged for use on large touch displays of 65 in. in size. We present a gesture elicitation study with 26 participants carried out on twelve actions commonly used on touch displays. The results and analysis of 312 touch gestures revealed agreement rates for each action. We report several findings including the results of a set of ten unique (and a few secondary) gestures, a taxonomy classifying the defined gestures, a pilot study on the defined gestures, and explicit design implications. We discuss the results and include several important factors for future considerations. We aim at helping future designers and engineers to design interactions for large touch displays.

Part 10: Workshops; International audience; Humor is a social phenomenon pervasive in all human societies. Due to its importance in interpersonal relations, in this workshop we are focusing onthe integration of humor in HCI exploring its benefits and downsides, as well as design and evaluation approaches for humorous machines. The workshop will provide a forum for discussions to all researchers and practitioners interested in this topic covering both verbal and non-verbal aspects of humor in HCI.

Part 8: Interactive Posters; International audience; Amazon recently opened its first intelligent retail store, which captures shopper movements, picked-up products and much more sensitive data. In this paper we present a privacy UI, called URetail, that returns to the customer control over his own data, by offering an interface to select which of his private data items should be disclosed. We use a radar metaphor to arrange the permissions with ascending sensitivity into different clusters, and introduce a new multi-dimensional form of a radar interface called the privacy pyramid. We conducted an expert interview and a pilot study to determine which types of data are recorded in an intelligent retail store, and grouped them with ascending sensitivity into clusters. A preliminary evaluation study shows that radar interfaces have their own strengths and weaknesses compared to a conventional UI.

Part 2: Methods and Tools for User Interface Evaluation; International audience; Worth Maps (WMs) are promising because they model interactive systems following different perspectives. Consequently, WMs support design in many ways. ARROW was introduced to provide designers with a systematic approach to worth mapping. However, the framework currently remains untested, which raises open questions about general applicability and relevance. In this work, we operationalize ARROW in additional design cases. With insights gained from the operational experience, we propose ARROWS (for ARROW-Support) as a refinement of the initial framework. ARROWS was assessed via a workshop with designers. Results highlight the need for appropriate resources supporting worth mapping. In order to fulfill this need, we have created and released a website providing designers with knowledge on ARROWS and WMs that follows a more practically oriented perspective.

Part 10: Workshops; International audience; Whilst usability has been the most prominent user interface property in early Human-Computer Interaction (HCI) research other properties such asaccessibility, inclusive design, user experience and, more recently security, trust and resilience (among many others) might also be important for the development of interactive system. It is interesting to notice that user interface properties might overlap and sometimes create conflicting recommendations. A good example is security which, by recommending users to deal with passwords reduces system usability by placing a burden on users. The ultimate goal of this workshop is to promote the investigation of multiple user interface properties in a user-centered design process. We are concerned by theories, methods and approaches for dealing with multiple user interface properties when developing interactive system. This workshop is organized by the IFIP WG 13.2 on Human-Centered Software Methodologies and the WG 13.5 on Resilience, Reliability, Safety and Human Error in System Development.
