In this paper, we present a novel multi-touch gesture-based authentication technique. We take advantage of the surface to combine biometric techniques with gestural input. defined comprehensive set five-finger touch gestures, based upon classifying movement characteristics center palm and fingertips, tested them in user study combining data collection usability questions. Using pattern recognition techniques, built classifier recognize unique gesture an individual. achieved 90% accuracy rate...
Commercial social VR applications represent a diverse and evolving ecology with competing models of what it means to be in VR. Drawing from expert interviews, this paper examines how the creators different think about their platforms frame, support, shape, or constrain interaction. The study covers range including: Rec Room, High Fidelity, VRChat, Mozilla Hubs, Altspace VR, AnyLand, Facebook Spaces. We contextualize design choices underlying these applications, particular attention paid ways...
A set of prominent designers embarked on a research journey to explore aesthetics in movement-based design. Here we unpack one the design sensitivities unique our practice: strong first person perspective—where movements, somatics and aesthetic sensibilities designer, researcher user are at forefront. We present an annotated portfolio exemplars brief introduction some methods theory use, together substantiating explaining first-person perspective. At same time, show how this felt dimension,...
Movement-based digital games are becoming increasingly popular, yet there is limited comprehensive guidance on how to design these games. We present a set of guidelines for movement-based game that has emerged from our research-based development practice. These have been examined and refined by 14 experts with experience in the academic, independent commercial domains. contextualize using current findings about interaction design, taken both published research papers venues. Our primary...
Activity in Human-Food Interaction (HFI) research is skyrocketing across a broad range of disciplinary interests and concerns. The dynamic heterogeneous nature this emerging field presents challenge to scholars wishing critically engage with prior work, identify gaps ensure impact. It also challenges the formation community. We present Systematic Mapping Study HFI an online data visualisation tool developed respond these issues. allows researchers new ways literature, propose modifications...
This paper investigates multitouch gestures for user authentication on touch sensitive devices. A canonical set of 22 was defined using characteristics hand and finger movement. Then, a gesture matching algorithm robust to orientation translation developed. Two different studies were performed evaluate the concept. First, single session experiment in order explore feasibility authentication. Testing showed that system could achieve good performance terms distinguishing between by users. In...
The emerging ecology of commercial social VR currently includes a diverse set applications and competing models what it means to be in VR. This study maps slice this ecology, comparing contrasting ways different frame, support, shape, or constrain interaction. We deploy method design-oriented autobiographical landscape research examine five platforms: Facebook Spaces, Rec Room, High Fidelity, VRChat, AltspaceVR. analyze design choices underlying these environments draw attention issues space...
In the emerging ecology of commercial social VR, avatars that serve to represent individuals within these multi-user virtual worlds are at heart embodied experience. Current industry approaches in VR applications vary widely, and (sometimes tacit) design knowledge acquired by those who created platforms has much offer research HCI. this paper, we describe current practices, reflect on characterize avatar systems sector. To investigate their impact communication interaction with people...
There is a growing interest in human-computer interaction (HCI) to envision, design, and evaluate technology-enabled interventions that support users’ emotion regulation. This stems part from increased recognition the ability regulate emotions critical mental health, lack of effective regulation transdiagnostic factor for illness. However, potential combine innovative HCI designs with theoretical grounding state-of-the-art psychology has yet be fully realised. In this article, we synthesise...
This paper introduces a new application area for agents in the computer interface: support of human-human interaction. We discuss an interface agent prototype that is designed to communication virtual environments. The interacts with users strategically during conversation, spending most its time listening. mimics party host, trying find safe common topic guests whose conversation has lagged. performed experimental evaluation prototype's ability assist cross-cultural conversations. introduce...
In this paper we describe the development and initial testing of a tool for self-assessment affect while interacting with computer systems: Sensual Evaluation Instrument. We discuss our research approach within context existing affective HCI theory, stages evolution tool, its effectiveness.
Movement-based digital games are becoming increasingly popular, yet there is limited comprehensive guidance on how to design these games. In this article we discuss a set of guidelines for movement-based game that were initially presented at CHI 2014 (Mueller & Isbister, 2014). These developed through reflection upon our research-based development practice and then validated refined interviews with 14 experts experience in the academic, independent, commercial domains. article, provide an...
Wearables are integrated into many aspects of our lives, yet, we still need further guidance to develop devices that truly enhance in-person interactions, rather than detract from them by taking people's attention away the moment and one another. The value this paper is twofold: first, present an annotated portfolio 'social wearables', namely technology designs worn on body augment co-located interaction. design work described can serve as inspiration for others. Then propose a framework...
