Urban spaces have a great impact on how people’s emotion and behaviour. There are number of factors that impact our brain responses to a space. This paper presents a novel urban place recommendation approach, that is based on modelling in-situ EEG data. The research investigations leverages on newly affordable Electroencephalogram (EEG) headsets, which has the capability to sense mental states such as meditation and attention levels. These emerging devices have been utilized in understanding how human brains are affected by the surrounding built environments and natural spaces. In this paper, mobile EEG headsets have been used to detect mental states at different types of urban places. By analysing and modelling brain activity data, we were able to classify three different places according to the mental state signature of the users, and create an association map to guide and recommend people to therapeutic places that lessen brain fatigue and increase mental rejuvenation. Our mental states classifier has achieved accuracy of (%90.8). NeuroPlace breaks new ground not only as a mobile ubiquitous brain monitoring system for urban computing, but also as a system that can advise urban planners on the impact of specific urban planning policies and structures. We present and discuss the challenges in making our initial prototype more practical, robust, and reliable as part of our on-going research. In addition, we present some enabling applications using the proposed architecture |

موجز عن البحث: | Subliminal techniques have been used to enhance and enrich the interaction efficiency between humans and computers. However, the extent to which they are effective when presented at the periphery of the visual field remains unexplored. In addition, it is still unclear which stimulus type is more effective at influencing decisions when presented in peripheral areas. In this work, we investigate the degree to which three types of subliminal stimuli (images, shapes, words) are effective at influencing selection decisions, and how their efficiency degrades when presented at different visual angles. In a controlled study, we examine the selection performance of subliminal stimuli that are presented at thirteen visual angles and tested using two presentation durations (33ms, 66ms). Our findings suggest that subliminal words can be effective at peripheral angles. Also, types comparison showed that the word stimulus outperformed other types at specific visual angles. These findings provide insights for understanding how peripheral subliminal techniques can be used to support users while performing primary tasks. We examine these findings, present potential use-case scenarios for peripheral subliminal techniques and discuss ethical considerations around their use in user interfaces. |

عنوان المشاركة: | An Exploratory Study for Evaluating the Use of Floor Visualisations in Navigation Decisions |
ملخص المشاركة: | Different environmental cues can influence our spatial behaviour when we explore unfamiliar spaces. Research shows that the presence of other people affects our navigation decisions. To investigate the use of this environmental cue as a navigation aid in novel environment, we first explore visualisations that represent historical presence of people. We carried out an exploratory study (n=12) to examine whether and how people understand and use floor visualisations to make their navigational choices. Results suggest that floor visualisations have influenced participants’ navigation decisions. Our findings showed that implicit visualisations were difficult to interpret compared to explicit visualisations. Thematic analysis of participants’ interpretations revealed a contextual interpretation of explicit visualisations and non-contextual interpretation of implicit visualisations. Additionally, thematic analysis revealed that spatial behaviour is influenced by several factors including self-centredness, environmental features and the presence of others. These design insights will inform the design of history-enriched floor interfaces that direct people in the built environment. |

Exploring the Design of History-Enriched Floor Interfaces for Asynchronous Navigation Support |
ملخص المشاركة: | Environmental cues influence our spatial behaviour when we explore unfamiliar spaces. Research particularly shows that the presence/actions of other people affects our navigation decisions. Here we examine how such social information can be integrated digitally into the environment to support navigation in indoor public spaces. We carried out a study (n=12) to explore how to represent traces of navigation behaviour. We compared 6 floor visualisations and examined how they affect participants’ navigational choices. Results suggest that direct representations such as footprints are most informative. To investigate further how such visualisation could work in practice, we implemented an interactive floor system and used it as probe during one-to-one design sessions (n=26). We particularly focused on four design challenges: the overall visual representation, representation of multiple people, designing more prominent visualisations and the incorporation of non-identifying information. Our results provide insights for designers looking to develop history-enriched floor interfaces. |
