Responses to Raven matrices: Governed by visual complexity and centrality

Raven matrices are widely considered a pure test of cognitive abilities. Previous research has examined the extent to which cognitive strategies are predictive of the number of correct responses to Raven items. This study examined whether response times can be explained directly from the centrality and visual complexity of the matrix cells ...

Demo Abstract: Catch My Eye: Gaze-Based Activity Recognition in an Augmented Reality Art Gallery

The personalization of augmented reality (AR) experiences based on environmental and user context is key to unlocking their full potential. The recent addition of eye tracking to AR headsets provides a convenient method for detecting user context, but complex analysis of raw gaze data is required to detect where a user's attention and thoughts...

The future roadmap of an artificial intelligent eye tracking platform

This thesis was performed in assignment of Alpha.One for their new eye tracking prediction platform expoze.io. The project started of with the brief; What does the future of expoze.io hold? This indicates the need for a future vision. In order to create a future vision the company purpose must first be researched, the reason why they exist. The...

Desktop lighting for comfortable use of a computer screen

BACKGROUND: The contrast between a bright computer screen and a dark ambient environment may influence comfort of the users, especially on their eyes. OBJECTIVE: The objective of this research is to identify the optimal desktop lighting for the comfortable use of the computer screen in a dark environment. METHODS: An experiment was designed...

The Effect of an Adaptive Simulated Inner Voice on User's Eye-gaze Behaviour, Ownership Perception and Plausibility Judgement in Virtual Reality

Virtual cognitions (VCs) are a stream of simulated thoughts people hear while emerged in a virtual environment, e.g. by hearing a simulated inner voice presented as a voice over. They can enhance people's self-efficacy and knowledge about, for example, social interactions as previous studies have shown. Ownership and plausibility of these VCs...

Human factors of monitoring driving automation: Eyes and Scenes

This PhD thesis document is a collection of several of my published (and submitted) peer review journal articles from underneath the Human Factors of Automated Driving (HF Auto, PITN-GA-2013-605817) seventh framework program (FP7) of the European Commission. The topics include: human factors, automotive road safety, autonomous/automated driving...

Using an eye tracker to measure developer focus while writing unit test from within the IDE

Background: Reading and understanding source<br/>code and writing test cases are indispensable parts of routine for<br/>modern software developers. Unit testing helps many developers<br/>to detect and prevent bugs at an early moment and is a cost-<br/>effective way to improve the effectiveness of a program. With the<br/>availability of portable...

Visual sampling processes revisited: replicating and extending senders (1983) using modern eye-tracking equipment

In pioneering work, Senders (1983) tasked five participants to watch a bank of six dials, and found that glance rates and times glanced at dials increase linearly as a function of the frequency bandwidth of the dial&amp;#x0027;s pointer. Senders did not record the angle of the pointers synchronously with eye movements, and so could not assess...

Adaptive Automation: Automatically (dis)engaging automation during visually distracted driving

Automated driving is becoming increasingly popular and is often proposed as a solution to commonly known human errors in driving. However, fully autonomous driving has not yet reached the point where it can be implemented in real world driving. Current automated driving systems are often designed in such a way that the role of the human operator...

Relating Eye Activity Measures to Human Controller Remnant Characteristics

This study attempts to partially explain the characteristics of the human perceptual remnant, following Levison’s representation of the remnant as an equivalent observation noise. Eye activity parameters are recorded using an eye tracker in two compensatory tracking tasks in which the visual information is presented using either a first or...

Image Quality Experience

While the world we live in becomes more saturated with ubiquitous digital displays, and as the threshold for creating digital media continues to drop, image quality is an issue that concerns an increasingly large segment of the population. Higher resolutions, increased dynamic range, and faster frame rates put increasing demands on resources...

PACT 2.0: The next level in measuring package design performance in an online shelf survey

Packaging design is one of the most important influences on shopping behaviour in competitive retail environments, especially in Fast Moving Consumer Goods. The package is often referred to as ‘the silent salesman’. Brand managers need to know how their package performs to identify if a package (re)design is going to improve sales or is a...

Studying the effect of optimizing the image quality in saliency regions at the expense of background content

Manufacturers of commercial display devices continuously try to improve the perceived image quality of their products. By applying some post processing techniques on the incoming image signal, they aim to enhance the quality level perceived by the viewer. Applying such techniques may cause side effects on different portions of the processed...
