MomentMeld: AI-augmented Mobile Photographic Memento towards Mutually Stimulatory Inter-generational Interaction
No full textAging often comes with declining social interaction, a known adversarial factor impacting the life satisfaction of senior population. Such decline appears even in family–a permanent social circle, as their adult children eventually go independent. We present MomentMeld, an AI-powered, cloud-backed mobile application that blends with everyday routine and naturally encourages rich and frequent inter-generational interactions in a family, especially those between the senior generation and their adult children. Firstly, we design a photographic interaction aid called mutually stimulatory memento, which is a cross-generational juxtaposition of semantically related photos to bring natural arousal of context-specific inter-generational empathy and reminiscence. Secondly, we build comprehensive ensemble AI models consisting of various deep neural networks and a runtime system that automates the creation of mutually stimulatory memento on top of the user’s usual photo-taking routines. We deploy MomentMeld in-the-wild with six families for an eight-week period, and discuss the key findings and further implications.1
A BoD (Back-of-Device) Interaction System for Instant VR Experience
No full text기존 모바일 HMD에서의 인터랙션은 컨트롤러를 활용하는 일반 HMD에 비해 한정된 입력 방식, 입력 시간의 지연 등의 단점을 갖고 있다. 우리는 이러한 한계를 보완하기 위해 Back-of-Device (BoD) 인터랙션을 활용하는 것을 제안한다. 구체적으로, 이 논문은 모바일 HMD에서 BoD 인터랙션을 가능하게 하는 TouchVR 시스템과 이의 전반적인 구조를 제안한다. 또한 Unity 어플리케이션에서 개발자가 손쉽게 활용할 수 있는 안드로이드 플러그인을 보인다. 이 과정에서 인터랙션을 인식하기 위해 참여자를 대상으로 센서 데이터를 수집, SVM 분류기를 학습시키고, 분류기의 성능을 검증한다. 더불어 360도 예시 어플리케이션을 개발하고 미래 적용 예를 제시하여 우리 시스템의 활용성을 보인다. 결론적으로, 우리의 시스템이 모바일 HMD가 즉각적 VR 경험에서 풍부한 인터랙션을 지원하는 발판이 될 것으로 기대한다.2
TouchVR: A Modality for Instant VR Experience
No full textIn near future, we envision instant and ubiquitous access to the VR worlds. However, existing highly portable VR devices usually lack rich and convenient input modality. In response, we introduce TouchVR, a system that enables BoD interaction in instant VR supported by mobile HMDs.
We present the overall architecture and prototype of the TouchVR system in Android platform, capable of being easily integrated to Unity-based mobile VR applications. Furthermore, we implement a sample application (360° video player) to demonstrate the usage of our system. Through TouchVR, we expect it to be a step for enriching interaction methods in instant VR.1
UAS Surveillance in Low-altitude Airspace with Geofencing: Constrained Stochastic Linear Hybrid Systems Approach
No full textHCI in the Pool: A Case for Swimming
No full textSwimming is one of the popular fitness activities. HCI related research includes topics such as assisting swimmers (e.g., record keeping and coaching) and gamifying swimming activities. In this position paper, we envision a wide range of swimming-based exertion games and explore various system design issues such as wearable sensor design, user interaction methods, platform support, and content design.1
Facilitating in-situ shared use of IoT actuators in public spaces
No full textPublic spaces, where we gather, commune, and take a rest, are the essential parts of a modern urban landscape, enriching citizen's everyday life [3]. How we share these spaces are considered an indicator of the quality of life. Public spaces thus have a responsibility to provide comfort and satisfaction to any visitors. However, in most times, the operations of the spaces are managed in rather an exclusive manner.1
SymmetriSense: Enabling Near-Surface Interactivity on Glossy Surfaces using a Single Commodity Smartphone
No full textDriven to create intuitive computing interfaces throughout our everyday space, various state-of-the-art technologies have been proposed for near-surface localization of a user's finger input such as hover or touch. However, these works require specialized hardware not commonly available, limiting the adoption of such technologies. We present SymmetriSense, a technology enabling near-surface 3-dimensional fingertip localization above arbitrary glossy surfaces using a single commodity camera device such as a smartphone. SymmetriSense addresses the localization challenges in using a single regular camera by a novel technique utilizing the principle of reflection symmetry and the fingertip's natural reflection casted upon surfaces like mirrors, granite countertops, or televisions. SymmetriSense achieves typical accuracies at sub-centimeter levels in our localization tests with dozens of volunteers and remains accurate under various environmental conditions. We hope SymmetriSense provides a technical foundation on which various everyday near-surface interactivity can be designed.1
Dyadic Mirror: Everyday Second-person Live-view for Empathetic Reflection upon Parent-child Interaction
No full textA parent's capacity to understand the mental states of both him/herself and the child is considered to play a significant role in various aspects of parent-child relationship-e.g., lowering parental stress and supporting cognitive development of the child. We propose Dyadic Mirror, a wearable smart mirror which is designed to foster the aforementioned parental capacity in everyday parent-child interaction. Its key feature is to provide a parent with a second-person live-view from the child, i.e., the parent's own face as seen by the child, during their face-to-face interaction. Dyadic Mirror serves as a straightforward cue that helps the parent be aware of (1) his/her emotional state, and (2) the way he/she would be now being seen by the child, thereby facilitate the parent to infer the child's mental state. To evaluate Dyadic Mirror under unconstrained parent-child interactions in real-life, we implemented the working prototype of Dyadic Mirror and deployed it to 6 families over 4 weeks. The participating parents reported extensive experiences with Dyadic Mirror, supporting that Dyadic Mirror has helped them be aware of their recurring but unconscious behaviors, understand their children's feelings, reason with the children's behaviors, and find self-driven momenta to better their attitude and expressions towards their children.1
