  abstract     = {{Projection-based assistive systems have shown to be a promising technology to support workers during manual assembly processes in industrial manufacturing by projecting instructions into the working area. While existing studies have investigated various aspects of these systems, little research has been conducted regarding the way in which the user accesses the provided instructions. In this paper we analyze the eye movements of users during the repeated execution of an assembly task at a projection-based assistive system in order to gain insights into the utilization of the presented instructions. For this purpose, we analyzed eye tracking recordings from a user study with 15 participants to investigate the sequences in which the respective instructions are observed by the users. The results show a significantly lower number of nonlinear gaze sequences as well as a significantly higher number of steps without observing the instructions during the repeated use of the assistive system. In addition, there was a significantly lower task completion time during repeated use of the assistive system.}},

  abstract     = {{When a user enters a personal identification number (PIN) into an automated teller machine or a point of sale terminal, there is a risk of some one watching from behind, trying to guess the PIN code. Such shoulder-surfing is a major security threat. In order to overcome this problem different PIN entry methods have been suggested. In this regard, gaze interaction methods are receiving attention in recent years, owing to the lowering cost of eye tracking technology. In this paper, we present SafetyPIN - an eye tracking based PIN entry system - which is aimed at making the PIN entry more secure with the help of an eye tracking device. We discuss the implementation and the initial evaluation of this system.}},

  abstract     = {{Today, usability measures for the evaluation of systems and interfaces are mostly assessed in an isolated way. This paper addresses the question whether an integrative multi-dimensional feature evaluation can lead to different and more holistic results. We combined traditional measures (e.g., time to task completion) with advanced measures, like eye tracking, biosignal data logging and assessment of user emotions. For the evaluation of emotions, we used verbal methods (PAD Semantic Scale and a questionnaire) and a nonverbal method with EmoCards. The overall goal was to document and analyze the interaction as completely as possible (including effectiveness, efficiency and user satisfaction), focusing especially on objective measurements. Furthermore, the recording and assessment of emotions, which are part of the user experience, should give insights into user satisfaction.}},
