Mine, yours, ours - family discussions on digital legacy

When people interact in internet spaces, they produce a many digital goods and assets, which compose their digital legacy when they pass away. Some systems provide solutions for users to decide how such legacies are to be managed when they are gone. As the companies that produce those systems may be imprinting the culture of their home country on them, it is worth asking, how do Brazilian families perceive the fate of digital legacies when faced with systems that offer this functionality? To answer this question, we carried out an exploratory research with a qualitative approach, with the objective of analyzing the usability of systems and the perceptions of families during the process of configuring digital legacy management in Google Inactive Account Manager and Facebook. This study was divided into two parts: 1) Evaluation of the usability of these systems through the Cognitive Walkthrough Method;and 2) Analysis of different perceptions of family members during the configuration process, as a family. All steps were carried out remotely, observing ethical precepts and restrictions due to the COVID-19 pandemic. The study revealed that most participants realized the importance of thinking about the destination of digital goods and reflected on this topic during the study, even considering the exclusion of goods. However, during the family interaction, some questions were raised associated with the emotional cost of participating in the study and the role of the family and its different generations, both in this decision and in relation to the lack of trust in the systems in charge of their digital assets. © 2022 ACM.

Visual Analysis Tool for a BLE Technology based Tracking Data

Several systems deal with human mobility. Most of them are for outdoor environments and use mobile phones to capture data. However, there is a growing interest of enterprises to consider indoor movement to take employees and client classes into account. Moreover, they usually want to assign semantics to the visited locations. We propose a visual exploration tool for analyzing the dynamics of individual movements in an indoor environment in this work. We present the use of suitable charts and animations to explore these complex data better. Finally, we argue that one could use our solution to monitor social distancing in indoor environments, which is a sensible thing during the current COVID-19 pandemic.

Yet another BLE technology based tracking system

There are numerous systems for analyzing human mobility for outdoor environments at the scale of large regions or entire cities. Most of them use mobile phones to capture data information. However, these systems are agnostic to a specific business field, do not consider indoor movement, do not take into account the participants' employee or client category, and usually do not assign semantics to the visited locations. In this work, we first developed a low-cost tracking system to detect, collect, process, and store users' movement and presence data in indoor environments. Such an approach takes into consideration the users' category and location semantic. We collected these data in two university buildings used by faculty, staff, and students. We suggest that our work could monitor social distancing in indoor environments due to its human presence detection capability, whenever required, such as for the COVID-19 pandemic. © 2021 Owner/Author.
