Intelligent Personal Assistants (IPAs) are widely available on devices such as smartphones. However, most people do not use them regularly. Previous research has studied the experiences of frequent IPA users. Using qualitative methods we explore the experience of infrequent users: people who have tried IPAs, but choose not to use them regularly. Unsurprisingly infrequent users share some of the experiences of frequent users, e.g. frustration at limitations on fully hands-free interaction. Significant points of contrast and previously unidentified concerns also emerge. Cultural norms and social embarrassment take on added significance for infrequent users. Humanness of IPAs sparked comparisons with human assistants, juxtaposing their limitations. Most importantly, significant concerns emerged around privacy, monetization, data permanency and transparency. Drawing on these findings we discuss key challenges, including: designing for interruptability; reconsideration of the human metaphor; issues of trust and data ownership. Addressing these challenges may lead to more widespread IPA use.

As worldwide population is aging and concentrating in cities, designing a pedestrian navigation aid adapted to elderly specificities and needs could help in preserving their autonomy, as their cognitive and perceptive abilities may decline with age. This study was aimed at comparing visual, auditory and haptic guidance feedbacks among older pedestrians, taking into account their navigation performance and user experience. A virtual environment was used to measure time to destination and rate of correct responses. Post-activity interviews were used to access participants' perceptions, feelings and hesitations in a qualitative way. Results showed great performance and user experience for visual guidance, whereas performance and user experience were poor for haptic guidance.

Wearable sports technology such as fitness trackers, smart watches or heart rate sensors has become ubiquitous in our everyday lives. This technology enables even recreational athletes to keep track of their workouts in a comprehensive manner. Besides the general assumption that this technology improves motivation to exercise more often, it also enables the athlete to get a better understanding of her current fitness level. However, current technology is mainly focussed on (quantifiable) performance indicators such as mileage, pace, cadence, watts, heart rate, etc. In this tutorial we aim to introduce wearable sports technologies that provide real-time support to athletes while exercising. Topics of interest range from engineering problems to research methods as they apply in the context of mobile and ubiquitous sports technologies.

Mobile devices are increasingly used while watching video, both as a secondary device and for dedicated viewing. However, devices frequently issue notifications that can interrupt viewing. This study investigated the effect of interruptions from notifications on viewer immersion. Participants watched 10 minutes of a movie without notifications, and 10 minutes while receiving message notifications. There were two participant groups: one watched video on a 30-inch monitor with messages sent to a separate smartphone; while another watched on a smartphone while also receiving messages on it. Viewer immersion was assessed after each condition via questionnaire. We also considered message response times. Results showed that immersion scores were lower when the video was interrupted with notifications, regardless of viewing device. Message response times were fastest when using the phone as a secondary device. Our results suggest that device-driven interruptions should be minimised for an immersive film experience.

Location based services are a common application scenario in mobile and ubiquitous computing use. A typical issue with cartographic applications in this domain is the limited size of the displayed map, which makes interaction and visualization a difficult problem to solve. With the increasing popularity of head mounted displays for VR and AR systems, an opportunity is presented for map-based applications to overcome the limitation of the small display size, as the user's information visualization space can extend to his entire surroundings. In this paper we present a preliminary investigation into how interaction with such very large display maps can take place, using a virtual reality headset as the sole input and interaction method.

We present a concept, prototype and in-the-wild evaluation of a mobile augmented reality (AR) application in which physical items from nature are used as AR markers. By blending the physical and digital, AR technology has the potential to create an enhanced learning experience compared to paper-based solutions and conventional mobile applications. Our prototype, an application running on a tablet computer, uses natural markers such as leaves and pinecones in a game-like nature quiz. The system was evaluated using interviews with and observations of 6- to 12-year-old children (n=11) who played the game as well as focus group discussions with play club counsellors (n=4) and primary school teachers (n=7). Our salient findings suggest that the concept has sound potential in its mixture of physical activity and educational elements in an outdoor context. In particular, teachers found the use of natural objects to be an appealing approach and a factor contributing to the learning experience.

Intelligent assistants are an emerging form of interface in digital devices. They are disrupting this space through conversations which have socio-cultural dimensions. However, what is not known are people's perceptions and expectations from these assistants. In this paper, we studied the Indian context through guided interviews and situational observations. The user-agent interaction begins with communication of intent. We found that Indians take a lot of time to articulate intent and also prefer conversing through type. Personalization and context are other two critical components, where latter gives deeper meaning to user intent and is culture specific. E.g. in India; security, shared public spaces and infrastructure availability are of higher importance as compared to the west. The need for user-profile building is identified as a key factor in adoption of assistive agents in India. We discuss influencing factors that will help build these user-profiles for Indian scenarios.

Many destinations' economies strongly rely on tourism. Therefore, it is crucial to meet tourists' expectations, so they will return to the destination. The geographical formation of certain touristic islands often leads to local climates where it can be rainy and windy on one side of the island, whereas the other part is sunny. In this paper, we present a novel use for a network of sensors, LightBeam, a mobile location-based application aiming to improve the tourists' experience. The application focuses on providing real-time guidance for tourists seeking sunlight to maximize their holiday experience by suggesting the closest points of interest (POIs) to the user with the "best sunlight". To achieve this, we implemented and installed a network of geospatial sensors. The data from the sensor network is combined with the current location of the users to provide recommendations. We report on the initial design and prototype of LightBeam.

SpeCam is a lightweight surface color and material sensing approach for mobile devices which only uses the front-facing camera and the display as a multi-spectral light source. We leverage the natural use of mobile devices (placing it face-down) to detect the material underneath and therefore infer the location or placement of the device. SpeCam can then be used to support discreet micro-interactions to avoid the numerous distractions that users daily face with today's mobile devices. Our two-parts study shows that SpeCam can i) recognize colors in the HSB space with 10 degrees apart near the 3 dominant colors and 4 degrees otherwise and ii) 30 types of surface materials with 99% accuracy. These findings are further supported by a spectroscopy study. Finally, we suggest a series of applications based on simple mobile micro-interactions suitable for using the phone when placed face-down.
