Ambiotherm: Enhancing Sense of Presence in Virtual Reality by Simulating Real-World Environmental Conditions

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025723

論文アブストラクト: In this paper, we present and evaluate Ambiotherm, a wearable accessory for Head Mounted Displays (HMD) that provides thermal and wind stimuli to simulate real-world environmental conditions, such as ambient temperatures and wind conditions, to enhance the sense of presence in Virtual Reality (VR). Ambiotherm consists of a Ambient Temperature Module that is attached to the user's neck, a Wind Simulation Module focused towards the user's face, and a Control Module utilizing Bluetooth communication. We demonstrate Ambiotherm with two VR environments, a hot desert, and a snowy mountain, to showcase the different types of simulated environmental conditions. We conduct several studies to 1) address design factors of the system and 2) evaluate Ambiotherm's effect on factors related to a user's sense of presence. Our findings show that the addition of wind and thermal stimuli significantly improves sensory and realism factors, contributing towards an enhanced sense of presence when compared to traditional VR experiences.

Multi-moji: Combining Thermal, Vibrotactile & Visual Stimuli to Expand the Affective Range of Feedback

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025614

論文アブストラクト: 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 of emotions within two-dimensional valence-arousal space. This paper is the first to systematically combine multiple modalities to expand the available affective range. Three studies were conducted: Study 1 measured the emotionality of vibrotactile feedback by itself; Study 2 measured the perceived emotional content of three bimodal combinations: vibrotactile + thermal, vibrotactile + visual and visual + thermal. Study 3 then combined all three modalities. Results show that combining modalities increases the available range of emotional states, particularly in the problematic top-right and bottom-left quadrants of the dimensional model. We also provide a novel lookup resource for designers to identify stimuli to convey a range of emotions

これまで単一モダリティのみで感情を表現する研究は行われてきた.そこで本研究では複数のモダリティを組み合わせて感情の表現を行った.結果,単一では出来ない感情を表現できたが,3つ以上組み合わせると混乱する被験者が存在した.

The Heat is On: A Temperature Display for Conveying Affective Feedback

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025844

論文アブストラクト: Previous research has investigated whether temperature can augment a range of media including music, images and video. We describe the first experiment to investigate whether temperature can augment emotion conveyed by text messages. A challenge in prior work has been ensuring users can discern different thermal signals. We present an improved technique for thermal feedback that uses an array of three thermal stimulators. We demonstrate that the Thermal Array Display (TAD) increases users' ability to identify temperatures within a narrower range, compared to using a single thermal stimulator. While text messages dominate valence in the absence of context for temperature, the TAD consistently conveys arousal, and can enhance arousal of text messages, especially those that are emotionally neutral. We discuss potential applications of augmenting text with temperature.

Exploring Novice Approaches to Smartphone-based Thermographic Energy Auditing: A Field Study

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025471

論文アブストラクト: The recent integration of thermal cameras with commodity smartphones presents an opportunity to engage the public in evaluating energy-efficiency issues in the built environment. However, it is unclear how novice users without professional experience or training approach thermographic energy auditing activities. In this paper, we recruited 10 participants for a four-week field study of end-user behavior exploring novice approaches to semi-structured thermographic energy auditing tasks. We analyze thermographic imagery captured by participants as well as weekly surveys and post-study debrief interviews. Our findings suggest that while novice users perceived thermal cameras as useful in identifying energy-efficiency issues in buildings, they struggled with interpretation and confidence. We characterize how novices perform thermographic-based energy auditing, synthesize key challenges, and discuss implications for design.
