The study of human mobility and activities has opened up to an incredible number of studies in the past, most of which included the use of sensors distributed on the body of the subject. More recently, the use of smart devices has been particularly relevant because they are already everywhere and they come with accurate miniaturized sensors. Whether it is smartphones, smartwatches or smartglasses, each device can be used to describe complementary information such as emotions, precise movements, or environmental conditions. In this short paper, we release the applications we have developed and an example of a collected dataset. We propose that opening multi-sensors data from daily activities may enable new approaches to studying human behavior. [less ▲]

The rapid emergence of new technologies in recent decades has opened up a world of opportunities for a better understanding of human mobility and behavior. It is now possible to recognize human movements, physical activity and the environments in which they take place. And this can be done with high precision, thanks to miniature sensors integrated into our everyday devices. In this paper, we explore different methodologies for recognizing and characterizing physical activities performed by people wearing new smart devices. Whether it’s smartglasses, smartwatches or smartphones, we show that each of these specialized wearables has a role to play in interpreting and monitoring moments in a user's life. In particular, we propose an approach that splits the concept of physical activity into two sub-categories that we call micro- and macro-activities. Micro- and macro-activities are supposed to have functional relationship with each other and should therefore help to better understand activities on a larger scale. Then, for each of these levels, we show different methods of collecting, interpreting and evaluating data from different sensor sources. Based on a sensing system we have developed using smart devices, we build two data sets before analyzing how to recognize such activities. Finally, we show different interactions and combinations between these scales and demonstrate that they have the potential to lead to new classes of applications, involving authentication or user profiling.

Smart and wearable devices are trendy electronic objects that have become increasingly popular in recent years. Those devices are, by definition, tightly connected with the user's personal activities. Authentication is therefore a critical feature for both identifying users and personalizing the services on the device. In particular, the emergence of smartglasses changed the way we thought a wearable could assist users in their daily activities. As designed by commercial providers, smartglasses are sold with a very specific set of interactions capabilities. These capabilities have a strong impact on how comfortably or safely users may authenticate to their smartglasses. For this reason, we investigate in this paper the different authentication methods available for smartphones and we comparatively position the smartglasses in the design space of authentication methods. We propose a new approach based on touch input on an arbitrary surface using thermal camera input. This approach aims to circumvent the lack of touch surface provided by smartglasses, while maintaining an acceptable level of security. [less ▲]

Despite the rapid pace of gadgets released on the market, research in the area of usable interfaces for wearables is lagging behind. Smartglasses are new wearables that embed diverse sensors but also have small displays, and this makes it hard for the wearer to visualize real-time data. To bridge this gap, the contribution of this paper is threefold. First, we propose a data representation model to combine applications and services that match user activities and contexts. Second, we present an approach of showing relevant services to the user based on 'tiles' (such as those in recent Microsoft Windows interfaces) while considering the device constraints. Finally, we suggest that combining those two aspects can open the way to personalized services for the end user, creating new ways of interacting with applications and devices. [less ▲]

The emergence of new connected devices has opened up new opportunities and allowed to imagine concepts that bring computer sciences and social sciences closer together. In particular, today's increasingly sophisticated miniature sensors allow to track and understand human activities and behavior with a great precision. Taking different approaches and perspectives, we use in this paper smartwatches and smartglasses to explore these behaviors and show that these objects, considered by many as gadgets, have an important role to play in understanding the lives of individuals. The main objective of this work is to introduce two new scales of activity detection, which lacks a formal and consistent definition in the literature. First, we propose a model that precisely detects and interprets movements made by a person wearing smart devices. Then, we use this model to show different interactions between those micro-activities and bigger chunks of behaviors we call macro-activities. Using a new concept based on 3D visualization, we finally show that combining those two scales and using a limited dataset, it is possible to distinguish between different individuals when they are performing very similar activities. The findings of this study lead the way to enhanced user profiling. [less ▲]

Innovative in-car applications provided on smartphones can deliver real-time alternative mobility choices and subsequently generate visual-manual demand. Prior studies have found that multi-touch gestures such as kinetic scrolling are problematic in this respect. In this study we evaluate three prototype tasks which can be found in common mobile interaction use-cases. In a repeated-measures design, 29 participants interacted with the prototypes in a car-following task within a driving simulator environment. Task completion, driving performance and eye gaze have been analysed. We found that the slider widget used in the filtering task was too demanding and led to poor performance, while kinetic scrolling generated a comparable amount of visual distraction despite it requiring a lower degree of finger pointing accuracy. We discuss how to improve continuous list browsing in a dual-task context. [less ▲]

This paper presents a comparative pilot usability study of Dasher and an on-screen keyboard on a head-mounted display. Interaction logging data was captured along with subjective responses (via the SUS questionnaire). The results indicate that there is a strong need to develop text entry systems for smart glasses rather to simply adopt those that are already available. However, both approaches are useful when there is a need to enter private or sensitive data. [less ▲]

We present a smart glasses application for helping colorblind people to distinguish problematic colors in daily life. The prototype processes a live video stream from the mobile camera, remaps colors according to the user needs, and displays the augmented result. Color transformation ensures high contrast between colors which are otherwise indistinguishable for the user. [less ▲]

In the future autonomous vehicles will drive on our roads. It is unlikely that we will immediately move from manual to fully autonomous vehicles, instead the mix will change over time and include a large number of semi-autonomous vehicles. As a result human drivers will need to take over in specific situations (e.g., when sensors fail) and there will be an interplay between autonomous systems and human agents. However, human drivers will not be able to practice driving so regularly. Our assumption is, that the reliance on semi-autonomous systems will lead to a deterioration in driving skills. In this paper, we present a three year project called MaDSAV (Maintaining Driving Skills in semi-Autonomous Vehicles), which tackles this problem. [less ▲]

Early research on head-worn computers (HWCs) has focused on hardware and specific applications. However, there is little research about the everyday usage of head-worn computers in particular aspects such as: context of use, social acceptance across different activities, audiences and interaction techniques. This paper provides insights into the use of head- worn computers by capturing the opinions of novice and expert users through a survey, a three-week diary study, and interviews. The overarching finding is that the context of use is critical, ei- ther due to the need to support micro-interactions, or because the interaction paradigm itself should depend on the context of use.

The purpose of this document is to review the requirements of the platform in terms of human factors issues that to be addressed, provide an update on the state of the art in augmented reality requirements and to provide an early technical specification. Addressing these issues will ensure that the platform can deliver its full potential when actually operated by the end-users. Indeed, a poorly designed system will not only reduce utility and acceptance of the platform but also induce discomfort and frustration. The document keeps the requirements at a general level as it does not support specific use-case implementations. Instead this document provides a list of general specifications and requirements that must be addressed in order for the eGlasses platform to be a success. [less ▲]

In this paper we explore how it can also be adopted during the conceptual design stage using metaphorical games and as a method of testing concepts within a more advanced simulation environment.

In this paper we present the DriveLab IVIS testing platform which allows for the same experiments to be conducted both under simulator and real car conditions. Other key aspects of DriveLab is that it is highly modular (therefore allowing the exchange or integration of different components) and that it supports more than one driver. For example we show that the same IVIS devices and scenario can be used with two different 3D engines. The paper provides a technical overview and a brief example of use. [less ▲]
