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 ▲]

Heat is in the Eye of the Beholder: Towards Better Authenticating on Smartglasses

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 ▲]

Toward a Characterization of Human Activities using Smart Devices: A Micro/Macro Approach

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 ▲]

Text entry on smart glasses A comparison of two input techniques

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 ▲]

MaDSAV: maintaining driving skills in semi-autonomous vehicles

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 ▲]

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 ▲]

Gamification is often thought of as the end result or outcome of a project. 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. We explore this from the perspective of the I-GEAR project where it is used as one of many methods in the design of a commuter mobility game. [less ▲]
