The amount of interactive digital technology in cars is increasing rapidly, and many new cars are shipped with connectivity. As a result, a new platform has emerged that holds potentials to facilitate many new and different interactions, both inside and outside the car. Within the area of HCI for cars, the focus has predominantly been on interactions with in-vehicle systems and applications of technology that is enabled through connectivity. However, we still lack in-depth empirical studies that provide details of the connected car, its use, opinions towards it, and how it integrates into people's everyday lives. We report from a qualitative study of 13 households with connected electric cars. We present our findings in 3 themes of interaction through connectivity, updating and upgrading car software, and security and privacy. We further discuss our findings in 3 themes that might inform and inspire further mobile HCI research with the connected car.

Though still a rare sight, body-worn lifelogging cameras such as Mofily's YoCam or the Narrative Clip have become increasingly popular amongst tech-savvy audiences. In this paper, we investigate whether users of those devices prefer to wear them openly or in a concealed, less obtrusive manner. We discuss the camouflage of lifelogging cameras based on results from an online study (N=117), including the why (not) and how as well as qualitative insights on how social contexts influence usage habits. The results of our study provide empirical evidence that deliberate concealment can be perceived unethical, and that moderate noticeability is favoured. We furthermore found contrary effects of lifelogging cameras in interpersonal relationships, including self-censorship by the user, avoidance behaviour by her/his peers and conversation starting character of the device itself. We conclude by highlighting design challenges concerning ubiquitous, body-worn cameras.

Being in nature is typically regarded to be calming, relaxing and purifying. When in nature, people often seek to be mobile through physical activity such as hiking. But also, nature provides an opportunity for meditative, mindful or inspiring experiences remote from urban everyday life. Mobile Technologies such as sports tracking technologies, electronic tourist guides, mobile phone integrated cameras and omnipresent social media access, have potential to both enhance and disrupt a user's interaction with and experience of nature. This MobileHCI workshop follows on from the first successful NatureCHI workshop by focusing on the challenges associated with the design of mobile technologies that support unobtrusive interaction in nature.

Previous work suggests that Quantified-Self applications can retain long-term usage with motivational methods. These methods often require intermittent attention requests with manual data input. This may cause unnecessary burden to the user, leading to annoyance, frustration and possible application abandonment. We designed a novel method that uses on-screen alert dialogs to transform recurrent smartphone usage sessions into moments of data contributions and evaluate how accurately machine learning can reduce unintended interruptions. We collected sensor data from 48 participants during a 4-week long deployment and analysed how personal device usage can be considered in scheduling data inputs. We show that up to 81.7% of user interactions with the alert dialogs can be accurately predicted using user clusters, and up to 75.5% of unintended interruptions can be prevented and rescheduled. Our approach can be leveraged by applications that require self-reports on a frequent basis and may provide a better longitudinal QS experience.

Even though the vast majority of children are online, our exploration of the user authentication literature and available tools revealed few alternatives specifically for authenticating children. We create an authentication mechanism that reduces the password burden for children and adds customizable parental oversight to increase security. With Bluink, our industry partner, we iteratively designed and user tested three parent-child prototypes, with each iteration addressing issues raised in the previous iteration. Our final design is a parent-child authentication mechanism based on OpenID and FIDO U2F which allows children to log in to websites without requiring a password and enables parents using their mobile device to remotely determine whether a login request should be granted.

Many researchers find themselves in a methodological rut and end up using the same tried-and-true user research methods, such as usability studies or interviews. Though these methods have their merits, there are times when asking questions directly may not suffice or researchers simply have trouble getting to the insights that are needed. This two-hour tutorial will focus on teaching creative methods that can spark new conversation or illuminate different insights. We will focus on three methods: speed-dating, love letters, and couple interviews. These methods are particularly effective for researchers and practitioners who study personal topics such as communication messaging apps and websites. The tutorial will provide a useful toolkit of creative methods and best practices.

This paper presents the work-in-progress prototype of i-Ribbon---a wearable device designed to elicit values in the context of weight loss. Starting with an Obesity Awareness Ribbon, we introduced the i-Ribbon concept. For prototyping, we built a system that could extract user's personal health-related data through a mobile application and sent it to a wearable device. The functional prototype enabled us to implement different interaction strategies to elicit corresponding values. Base on the reflection on design and prototyping process, possibilities of future research were identified.

Today, ambitioned amateur athletes often do not have access to professional coaching but still invest great effort in becoming faster runners. Apart from a pure increase in the quantitative training load, a change of the running technique, e.g. transitioning from heel striking to fore- or midfoot running, can be highly effective and usually prevents knee-related injuries. With this demo, we highlight factors to consider when determining EMS actuation phases for real-time running style correction in an outdoor scenario. During actuation the wearable applies electrical muscle stimulation (EMS) in the flight phase of a stride after having detected a heel-strike with force sensing resistors (FSR) in a sensor insole. To complement the original FootStriker lab prototype, we address the applicability in the field of the aforementioned real-time running style correction system.

Smartwatches are growing in usage, yet they come with the additional challenge of regulating their usage during the taking of academic tests. However, it is unclear how effective they are at actually allowing students to cheat. We conducted an experiment that examines the use of smartwatches for cheating on Multiple-Choice Questions (MCQ) and Short Answers (SA) with either Pictures/Text shown on the watch to aid students. Our results indicate that smartwatches are neither efficient nor have a high usability rating for cheating. However, students are able to score higher on Multiple-Choice Questions compared to Short Answers. We use the cheating paradigm as an example to understand the perceived usability and appropriation of smartwatches in an academic setting. We provide suggestions that help to deter cheating in an academic setting. Our study contributes to the research on academic integrity and the growing demand of wearable technologies.

Today we can see an increasing number of object recognition systems of very different sizes, portability, embedability and form factors which are starting to become part of the ubiquitous, tangible, mobile and wearable computing ecosystems that we might make use of in our daily lives. These systems rely on a variety of technologies including computer vision, radar, acoustic sensing, tagging and smart objects. Such systems open up a wide-range of new forms of touchless and mobile interaction. With systems deployed in mobile products then using everyday objects that can be found in the office or home, we can realise new applications and novel types of interaction. Object based interactions might revolutionise how people interact with a computer. System could be used in conjunction with a mobile phone, for example it could be trained to open a recipe app when you hold a phone to your stomach, or change its settings when operating with a gloved hand. Although the last few years have seen an increasing amount of research in this area, knowledge about this subject remains under explored, fragmented, and cuts across a set of related but heterogeneous issues. This workshop brings together researchers and practitioners interested in the challenges posed by Object Recognition for Input and Mobile Interaction.
