There are inherent associations between temperature and emotion in language, cognition subjective experience [22,42]. However, there exists no systematic mapping of thermal feedback to models that could be used by designers users convey a range emotions HCI. A common way classifying quantifying emotional is through ratings along valence arousal dimensions, originating from Russell's circumplex model [32]. Therefore, the research this paper mapped stimuli understand might conveyed feedback....
Ultrasonic haptic feedback is a promising means of providing tactile sensations in mid-air without encumbering the user with an actuator. However, controlled and rigorous HCI research needed to understand basic characteristics perception this new medium, so how best utilise ultrasonic haptics interface.

This paper explores the combination of multiple concurrent modalities for conveying emotional information in HCI: temperature, vibration and abstract visual displays. Each modality has been studied individually, but can only convey a limited range emotions within two-dimensional valence-arousal space. is first to systematically combine expand available affective range. Three studies were conducted: Study 1 measured emotionality vibrotactile feedback by itself; 2 perceived content three...
Individuals with mental disorders are at an elevated risk of developing chronic age-related physical diseases. However, it is not clear whether psychopathology also associated processes accelerated aging that precede the onset disease.To test hypothesis a history indicators midlife.This prospective cohort study was based on Dunedin Multidisciplinary Health and Development Study, population-representative birth 1037 individuals born between April 1, 1972, March 31, 1973, in Dunedin, New...
Extended Reality (XR) technology brings exciting possibilities for aeroplane passengers, allowing them to escape their limited cabin space. Using nearby physical surfaces enables a connection with the real world while improving XR experience through touch. However, available may be located in awkward positions, reducing comfort and input performance thus limiting long-term use. We explore usability of passive haptic different orientations, assessing effects on performance, user comfort. then...
Climate change will result in warmer temperatures and an increase the frequency severity of extreme weather events. Given that higher reproductive rate temperate zone insects, insect population growth rates are predicted to response climate. This consensus, however, rests on assumption food is freely available. However, under conditions limited food, output Texan cricket Gryllus texensis (Cade Otte) was highest at its current normal average temperature declined with increasing temperature....
This paper expands the repertoire of non-visual feedback for mobile interaction, established through Earcons and Tactons, by designing structured thermal cues conveying information. Research into use HCI has not looked beyond basic 'yes-no' detection stimuli to unique identification those stimuli. We first designed icons that varied along two parameters convey pieces also intramodal tactile icons, combining one vibrotactile parameter, test perception different so evaluate possibility...
Room-scale Virtual Reality (VR) has become an affordable consumer reality, with applications ranging from entertainment to productivity. However, the limited physical space available for room-scale VR in typical home or office environment poses a significant problem. To solve this, spaces can be extended by amplifying mapping of virtual movement (translational gain). Although amplified been used since earliest days VR, little is known about how it influences reach-based interactions objects,...
Auditory headsets capable of actively or passively intermixing both real and virtual sounds are in-part acoustically transparent. This paper explores the consequences acoustic transparency, on perception audio content, given presence a real-world auditory backdrop, more broadly in facilitating wearable, personal, private, always-available soundspace. We experimentally compare passive transparent, active noise cancelling, orientation-tracked across range content types, indoors outdoors for...
We present PassengXR, an open-source toolkit for creating passenger eXtended Reality (XR) experiences in Unity. XR allows travellers to move beyond the physical limitations of in-vehicle displays, rendering immersive virtual content based on - or ignoring vehicle motion. There are considerable technical challenges using headsets moving environments: maintaining forward bearing IMU-based headsets; conflicts between optical and inertial tracking inside-out obtaining telemetry; high cost design...
Standalone Virtual Reality (VR) headsets can be used when travelling in cars, trains and planes. However, the constrained spaces around transport seating leave users with little physical space which to interact using their hands or controllers, increase risk of invading other passengers' personal hitting nearby objects surfaces. This hinders VR from most commercial applications, are designed for unobstructed 1-2m 360 ° home spaces. In this paper, we investigated whether three at-a-distance...
Augmented Reality (AR) headsets could significantly improve the passenger experience, freeing users from restrictions of physical smartphones, tablets and seatback displays. However, confined space public transport varying proximity to other passengers may restrict what interaction techniques are deemed socially acceptable for AR - particularly considering current reliance on mid-air interactions in consumer headsets. We contribute utilize a novel approach social acceptability video surveys,...
Despite many successes in desktop applications, little work has looked at the use of pressure input on mobile devices and different issues associated with interactions e.g. non-visual feedback. This study examined a device using single Force Sensing Resistor (FSR) linearised output as means target selection within menu, where menu items varied size location along z-axis. Comparing visual audio feedback, results showed that, overall, eyes-free interaction reached mean level 74% accuracy. With...
Thermal feedback is a new area of research in HCI and, as such, there has been very little investigation the impact environmental factors on its use for interaction. To address this shortcoming we conducted an experiment to investigate how ambient temperature and humidity could affect usability thermal feedback. If conditions perception significantly, then it may not be suitable mobile interactions. Evaluations were outdoors varying over period 5 months. Results showed that significant...
