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 ▲]

In this paper we provide an overview of the I-GEAR (incentives and gaming environments for automobile routing) project that is intended to reduce traffic congestion in Luxembourg through the use of persuasive gaming. In order to illustrate some of the issues involved we also present an outline concept of a live game in which we propose to encourage the workshop participants to take part. If a sufficient number of workshop participants take part, this real life game could even be used as a small scale study within the project. [less ▲]

This paper presents an architecture and partially built simulation platform which is designed to offer a flexible open ended approach for conducting laboratory experiments. The emphasis is on supporting multiple drivers and the ability to swap in and out different software components and devices. [less ▲]

In this paper the authors explain the use of gamification as a way to optimize mobility patterns within a heav- ily congested European City. They explore this from two perspectives, first by outlining a gaming concept and secondly by explaining how the use of a mobility game that took place in two locations can be used to explore incentives and design issues.

Gaming concepts and incentives to change driver behaviour

In this paper we present a novel concept that deals specifically with changing driver behaviour in order to reduce traffic congestion. The project I-GEAR (incentives and gaming environments for automobile routing) aims to understand the motivations that drivers have while undertaking the daily commute and then to provide them with a range of incentives to change their behaviour. A key focus within the project is on ways in which the problem could potentially be solved without recourse to an expensive infrastructure project. Our solution to this problem was to move the problem of traffic management onto everyday mobile devices. In the following paper we outline the background to the problem, concepts relating to pervasive gaming, existing explorations of incentives and gaming approaches as well as our basic concept and project methodology.

We present a novel technique implementing barehanded interaction with virtual 3D content by employing a time-of-flight camera. The system improves on existing 3D multi-touch systems by working regardless of lighting conditions and supplying a working volume large enough for multiple users. Previous systems were limited either by environmental requirements, working volume, or computational resources necessary for realtime operation. By employing a time-of-flight camera, the system is capable of reliably recognizing gestures at the finger level in real-time at more than 50 fps with commodity computer hardware using our newly developed precision hand and finger-tracking algorithm. Building on this algorithm, the system performs gesture recognition with simple constraint modeling over statistical aggregations of the hand appearances in a working volume of more than 8 cubic meters. Two iterations of user tests were performed on a prototype system, demonstrating the feasibility and usability of the approach as well as providing first insights regarding the acceptance of true barehanded touch-based 3D interaction.

Let’s Do the Time Warp Again – Subjective and Behavioral Presence Measurement in the Augmented Reality Game TimeWarp

Presence measurements are traditionally using a variety of subjective and objective measures. However, constraints often result in subjective measurements using questionnaires as a key method of data collection. In this paper we present a study of 44 participants of an augmented reality game known as TimeWarp which used both subjective and objective behavioural measures where both video recordings and self- reports about feelings of presence were compared. Our findings indicate that pointing behaviour and verbal responses to virtual content within an augmented reality scene are correlated negatively to sense of presence. As a result the paper indicates that there are behavioural measures that correlate and can predict subjective feelings of presence in the augmented reality game. [less ▲]

This paper presents an overview of a study of 24 people who used an augmented reality game called TimeWarp. The paper initially discusses the game and evaluation methods chosen, it then explores emerging issues from the evaluation which are applicable to other augmented reality games and how existing user testing methods require further improvements in order to capture data relevant to the issues.

Mobile location-aware applications have become quite popular across a range of new areas such as pervasive games and mobile edutainment applications. However it is only recently, that approaches have been presented which combine gaming and education with mobile Augmented Reality systems. However they typically lack a close crossmedia integration of the surroundings, and often annotate or extend the environment rather than modifying and altering it. In this paper we present a mobile outdoor mixed reality game for exploring the history of a city in the spatial and the temporal dimension. We introduce the design and concept of the game and present a universal mechanism to define and setup multi-modal user interfaces for the game challenges. Finally we discuss the results of the user tests. [less ▲]

Responsive Environments, Place and Presence

This paper examines the effect that changing arena (i.e. an immersive CAVE or head mounted display) and adding an augmented barrier has on the sense of place and presence in two photo-realistic virtual environments. Twenty eight subjects (17 male, 11 female) mainly undergraduate students or staff took part. The paper summarises two experiments that used a range of data capture methods including the place probe, semantic differentials, distance estimates and the MEC Questionnaire. The results indicate that in non-interactive photo-realistic environments the choice of arena has an impact on the perceived ability to undertake actions, and hence sense of place and presence; with the CAVE providing a lower sense of spatial presence for certain aspects than the HMD.
