Introduction
My research combines behavioural and neuroimaging techniques in order to investigate how spatial information is encoded and used to guide navigation. I am interested in understanding individual differences in navigation ability and the extent to which locomotion and wayfinding depend on amodal spatial representations. Recently, I have investigated how physiological measures (e.g., EDA, HR) mediate behavior in real and virtual environments. Much of my research relies on the development of immersive virtual environments that can mimic real-world situations. As such, I have worked with computer scientists to develop a framework (EVE) to facilitate the design and implementation of experiments in virtual reality. This work has resulted in projects in the digital humanities and public health.

Article
The idea that humans use flexible map-like representations of their environment to guide spatial navigation has a long and controversial history. One reason for this enduring controversy might be that individuals vary considerably in their ability to form and utilize cognitive maps. Here we investigate the behavioral and neuroanatomical signatures...

Spatial navigation in the absence of vision has been investigated from a variety of perspectives and disciplines. These different approaches have progressed our understanding of spatial knowledge acquisition by blind individuals, including their abilities, strategies, and corresponding mental representations. In this review, we propose a framework...

Living in a disadvantaged neighborhood is associated with worse health and early mortality. Although many mechanisms may partially account for this effect, disadvantaged neighborhood environments are hypothesized to elicit stress and emotional responses that accumulate over time and influence physical and mental health. However, evidence for neighb...

Exploring a city panorama from a vantage point is a popular tourist activity. Typical audio guides that support this activity are limited by their lack of responsiveness to user behavior and by the difficulty of matching audio descriptions to the panorama. These limitations can inhibit the acquisition of information and negatively affect user exper...

The role of affective states in learning has recently attracted considerable attention in education research. The accurate prediction of affective states can help increase the learning gain by incorporating targeted interventions that are capable of adjusting to changes in the individual affective states of students. Until recently, most work on th...

Article
Sensors have become ubiquitous in buildings but are rarely connected to a network, and their potential to analyse the performance, use, and interaction with a building is not yet fully realised. In the coming years, we expect sensors in buildings to become part of the Internet of Things (IoT) and grow in numbers to form a Dense Indoor Sensor Networ...

In the event of fires and other hazards, visual guidance systems that support evacuation are critical for the safety of individuals. Current visual guidances for evacuations are typically non-adaptive signs in that they always indicate the same exit route independently of the hazard’s location. Adaptive signage systems can facilitate wayfinding dur...

Conference Paper
The inspection of feature-rich information spaces often requires supportive tools that reduce visual clutter without sacrificing details. One common approach is to use focus+context lenses that provide multiple views of the data. While these lenses present local details together with global context, they require additional manual interaction. In th...

Conference Paper
Current Mixed Reality (MR) systems rely on a variety of sensors (e.g., cameras, eye tracking, GPS) to create immersive experiences. Data collected by these sensors are necessary to generate detailed models of a user and the environment that allow for different interactions with the virtual and the real world. Generally, these data contain sensitive...

The collective behavior of human crowds often exhibits surprisingly regular patterns of movement. These patterns stem from social interactions between pedestrians such as when individuals imitate others, follow their neighbors, avoid collisions with other pedestrians, or push each other. While some of these patterns are beneficial and promote effic...

Cognitive neuroscience can provide novel and interesting techniques for investigating spatial and geographic thinking. However, the incorporation of neuroscientific methods still lacks the theoretical motivation necessary for the progression of geography as a discipline. Rather than reflecting a shortcoming of neuroscience, this weakness has develo...

Telling stories is as old as humanity. It was Herodotus (484-425 BCE), the Greek scholar often known as the "father of history", who proclaimed in The Histories both our collective reasons and worries about preserving stories. He wrote: This is the display of the inquiry of Herodotus of Halicarnassus, so that things done by man not be forgotten i...

Previous research in spatial cognition has often relied on simple spatial tasks in static environments in order to draw inferences regarding navigation performance. These tasks are typically divided into categories (e.g., egocentric or allocentric) that reflect different two-systems theories. Unfortunately, this two-systems approach has been insuff...

Article
Using novel virtual cities, we investigated the influence of verbal and visual strategies on the encoding of navigation-relevant information in a large-scale virtual environment.

Poster
Abstract. EVE (Experiments in Virtual Environments), is a novel VR framework that allows researchers to setup, execute and evaluate experiments in virtual environments (VE). By automating different steps, EVE reduces the time and costs associated with the development and evaluation of experiments in VE. The framework operates under the platform of...

We present the results of a study that investigated the interaction of strategy and scale on search quality and efficiency for vista-scale spaces. The experiment was designed such that sighted participants were required to locate “invisible” objects whose locations were marked only with audio cues, thus enabling sight to be used for search coordina...
Conference Paper
A major issue with virtual reality (VR) studies in spatial cognition is the dissociation of spatial ability from the capacity to use human interface devices (HID) such as joystick/gamepad and mouse. Previous research has found large individual differences in spatial navigation in both real and virtual worlds (Wolbers & Hegarty, 2010; Ishikawa & Mon...

We investigated the interpolation of missing values in data that were fit by bidimensional regression models. This addresses a problem in spatial cognition research in which sketch maps are used to assess the veracity of spatial representations. In several simulations, we compared samples of different sizes with different numbers of interpolated co...

There are marked individual differences in the formation of cognitive maps both in the real world and in virtual environments (VE; e.g., Blajenkova, Motes, & Kozhevnikov, 2005; Chai & Jacobs, 2010; Ishikawa & Montello, 2006; Wen, Ishikawa, & Sato, 2011). These differences, however, are poorly understood and can be difficult to assess except by self...

Search, like navigation, is a key element of spatial strategy expression. Although many studies have looked at search strategies for the visually impaired, relatively few have looked at search strategies for sighted individuals.

Article
Classical theories of spatial microgenesis (Siegel and White, 1975) posit that information about landmarks and the paths between them is acquired prior to the establishment of more holistic survey-level representations. To test this idea, we examined the neural and behavioral correlates of landmark and path encoding during a real-world route learni...
