Nikkels, Lucile (author)Robots in classroom settings can help teachers with providing personalised attention to children's health and development. As part of this personalisation, robots should store and use (verbal or multi-modal) information about the children they interact with. One aspect that has been unexplored in existing literature is the detection of memorable...master thesis 2023

Schuurman, Jesse (author)Background: Treatment of eye conditions, such as retinal detachment, macular pucker or macular holes, ask for an intervention named ”vitrectomy”. In a vitrectomy, multiple surgical instruments are brought into the eye, to facilitate removal of the vitreous humor. The instruments enter the eye through trocar ports that are placed in the sclera....master thesis 2023

Remeijsen, Pascal (author)Virtual cognitions are simulated inner thoughts, which are presented as a voice over. Previous research has shown the ability of virtual cognitions to increase the self-efficacy and knowledge of the users. When presenting such VR systems to users, having the VR system adapt to the user can improve their efficacy. For instance, by using eye-gaze...master thesis 2023

Lussenburg, K.M. (author), Scali, Marta (author), Stolk, Maarten (author), Robijns, D. (author), Sakes, A. (author), Breedveld, P. (author)A vitrectome is a commonly used instrument in eye surgery, which is used to cut and aspirate the vitreous body out of the eye. The mechanism of the vitrectome consists of miniature components that need to be assembled by hand due to their size. Non-assembly 3D printing, in which fully functional mechanisms can be produced in a single production...journal article 2023

van Asten, T. (author), Milias, V. (author), Bozzon, A. (author), Psyllidis, A. (author)Neighborhood safety and its perception are important determinants of citizens’ health and well-being. Contemporary urban design guidelines often advocate urban forms that encourage natural surveillance or “eyes on the street” to promote community safety. However, assessing a neighborhood’s level of natural surveillance is challenging due to its...book chapter 2023

de Winter, J.C.F. (author), Koelmans, T.A. (author), Kokshoorn, M.H.J.L. (author), van der Valk, K.P. (author), Vos, Willem (author), Dodou, D. (author), Eisma, Y.B. (author)Chunking theory and previous eye-tracking studies suggest that expert chess players use peripheral vision to judge chess positions and determine the best moves to play. However, the role of peripheral vision in chess has largely been inferred rather than tested through controlled experimentation. In this study, we used a gaze-contingent paradigm...journal article 2023

Eisma, Y.B. (author), Bakay, A. (author), de Winter, J.C.F. (author)Introduction<br/>In the 1950s and 1960s, John Senders carried out a number of influential experiments on the monitoring of multidegree-of-freedom systems. In these experiments, participants were tasked with detecting events (threshold crossings) for multiple dials, each presenting a signal with different bandwidth. Senders’ analyses showed a...journal article 2023

Onkhar, V. (author), Dodou, D. (author), de Winter, J.C.F. (author)Over the past few decades, there have been significant developments in eye-tracking technology, particularly in the domain of mobile, head-mounted devices. Nevertheless, questions remain regarding the accuracy of these eye-trackers during static and dynamic tasks. In light of this, we evaluated the performance of two widely used devices: Tobii...journal article 2023

de Winter, J.C.F. (author), Dodou, D. (author), Eisma, Y.B. (author)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 ...journal article 2023

Mulder, Jelmer (author)In the Netherlands roughly 20.000 people wear an ocular prosthetic as a consequence of losing their eye due to an accident or disease. An ocular prosthetic is a type of facial prosthesis that replaces an absent natural eye. The main goal of an ocular prosthetic is to provide an aesthetic replacement of a real eye. It does not restore the ability...master thesis 2022

Haasjes, Corné (author)Ultrasound imaging is an important modality in ocular oncology, allowing for fast examination of the eye by the ophthalmologist themselves. It is clinically used to measure tumour sizes for treatment planning. However, ocular ultrasound is limited to two-dimensional imaging, and suffers from poor contrast between tumour and sclera, which...master thesis 2022

Addi, Rhita (author)With the introduction of automated driving systems come benefits such as the improvement of traffic safety. However, with an increasing level of automation in vehicles also comes an increase in interaction with in-vehicle technology by drivers while they are meant to supervise the automated driving systems. Due to more interaction with in...master thesis 2022

Lucas, Valentin (author)Retinal detachment occurs when liquid slips behind the retina and does not allow the latter to lay flat on the posterior region of the eye. It alters the vision of the patient, hence requiring surgery to be corrected. In some cases, retinal detachment can occur after the retina has been treated for other pathologies. <br/>Indeed, more than 20%...master thesis 2022

Poeth, Ole (author)Cognitive processes have been used in recent years for context sensing and this has shown promising results. Multiple sets of features have shown good performance but no set of features has been determined the best for classifying gaze data. This paper looks at different feature sets and the heterogeneity of gaze signals from subjects and...bachelor thesis 2022

Chatalbasheva, Violeta (author)Sedentary activity recognition is an important research field due to its various positive implications in people’s life. This study builds upon previous research which is based on low level features extracted from the gaze signals using a fixation filter and uses a dataset of 24 participants performing 8 different sedentary activities. The main...bachelor thesis 2022

van Dijk, Max (author)Mind wandering is a phenomenon that is used to describe moments where a person's attention appears to shift away to something that is not related to the primary task, which can have a negative influence on the task performance. In this research, the aim is to create a viable algorithm that can automatically detect mind wandering based on eye...bachelor thesis 2022

Huang, Stephen (author)Distance learning brings all sorts of advantages. The ability to follow lectures at home can save people transportation costs and time. Teaching through videoconferencing software such as Zoom is one of the methods to learn remotely. To explore new and better teaching methods, the possibility of using a telepresence robot is investigated. To...bachelor thesis 2022

Struijk, Dave (author)People who perform work on micro-task crowdsourcing platforms, often do so using a mouse and/or keyboard for many hours at a time, while alternative modes of input could potentially provide a better experience. This research investigates the feasibility of using webcam-based eye-tracking in a micro-task work environment. We accomplish this by...bachelor thesis 2022
