The server-based algorithm uses a Bayesian Network that employs probabilistic computation to model each user's interpersonal relationships. When multiple CaraClock devices are synchronized, they display related photos according the settings. This often results in serendipitous discoveries for the whole family by reminding
Floral Tribute Ritual in Virtual Reality: Design and Validation of SenseVase with Virtual Memorial

In this research, these features of flowers are intertwined with the recent phenomenon of online memorials to develop a virtual floral tribute concept that includes physical rituals. We designed SenseVase, a smart vase to detect flowers placed in it, and a 3DCG Virtual Memorial that illustrates floral tributes given by people using SenseVases at home. This paper describes how we developed our design concept by reviewing previous literature and social aspects, and presents a video illustrating the concept. To validate the current concept, we interviewed several experts knowledgeable in public commemorations, virtual and online communities, and the floral business. Through a discussion of our findings from the design process and interviews, we propose a new direction for how HCI technology can contribute to public commemoration in addition to personal memorialization.
Generating the Presence of Remote Mourners: a Case Study of Funeral Webcasting in Japan
Funerals are irreplaceable events, especially for bereaved family members and relatives. However,... more Funerals are irreplaceable events, especially for bereaved family members and relatives. However, the COVID-19 pandemic has prevented many people worldwide from attending their loved ones’ funerals. The authors had the opportunity to assist one family faced with this predicament by webcasting and recording funeral rites held near Tokyo in June, 2020. Using our original 360-degree Telepresence system and smartphones running Zoom, we enabled the deceased’s elder siblings to remotely attend the funeral and did our utmost to make them feel present in the funeral hall. Despite the webcasting via Zoom contributing more to their remote attendances than our system, we discovered thoughtful findings which could be useful for designing remote funeral attendances. From the findings, we also discuss how HCI designers can contribute to this highly sensitive issue, weaving together knowledge from various domains including techno-spiritual practices, thanato-sensitive designs; and other religious and cultural aspects related to death rituals.

As a result, today many people can enjoy expressiveness of photography compared to the fact that only limited people were allowed to

It senses when incense chips are placed into it and the volume of incense smoke that is produced as the chips burn. Data captured from the integrated sensors can be connected to various applications, such as lighting equipment, sound systems, displays showing moving images, and more specific installations in particular rituals. We designed SenseCenser to investigate the potential role and place of interactive technologies in supporting Japanese funeral and memorialization rituals, as well as how it could be applied to other incense practices in different cultural contexts and settings.

STAMPER consists of several "Actuated Pedals (APs)," bass drum pedals embedded with an EC motor, paired with bass drums, and a machine vision system. The APs are used both as input and output. One AP in input mode senses the position of the pedal being used by the drummer. Other APs in actuated mode respond to the input mode AP's motion. Machine vision is used to monitor the drummer's movements to control the behavior of the actuated APs. In this paper, we describe the current prototype of STAMPER and what kind of drum performances can be achieved with the system by reporting a study conducted with an experienced drummer. CCS CONCEPTS • Human-centered computing → Human computer interaction (HCI).

A New Mask for a New Normal: Investigating an AR Supported Future under COVID-19

However, these are increasingly seen as a source of frustration in face-to-face communications. While efforts have been made to overcome these impediments to communication, they typically focus on recovering lost communication quality. Herein, we envision a future where everyone augments their vision using face masks with Augmented Reality capabilities, such that people can conduct safe and expressive face-to-face communication in public. To speculate on this vision, we developed an AR mask prototype which can overlay dynamic virtual “masks” on other users. The virtual mask is dynamic in that it accelerates towards any observer who approaches the wearer. Using this system, we conducted an explorative study to further our speculations on the impact of ubiquitous AR technologies.
