TL;DR
This paper explores the challenges of visualizing real-time data needs for athletes during outdoor activities, proposing a corpus collection, research challenges, and a prototype tool to support context-aware visualization.
Contribution
It introduces a novel corpus of egocentric data paired with athletes' information needs and proposes initial design considerations and a prototype for in-context visualization during outdoor activities.
Findings
Collected a diverse corpus of egocentric video, biometrics, and think-aloud data.
Identified key research challenges for in-motion visualization.
Developed a prototype tool for browsing and analyzing activity-related data.
Abstract
We investigate research challenges and opportunities for visualization in motion during outdoor physical activities via an initial corpus of real-world recordings that pair egocentric video, biometrics, and think-aloud observations. With the increasing use of tracking and recording devices, such as smartwatches and head-mounted displays, more and more data are available in real-time about a person's activity and the context of the activity. However, not all data will be relevant all the time. Instead, athletes have information needs that change throughout their activity depending on the context and their performance. To address this challenge, we describe the collection of a diverse corpus of information needs paired with contextualizing audio, video, and sensor data. Next, we propose a first set of research challenges and design considerations that explore the difficulties of…
