Becoming Watchful on the Trail and at Home: Understanding Experiential Outcomes of Capra in Long-Term Use

Publication Info

• Topic area: Long-term human-computer interaction (HCI) research on technology-mediated human-nature relations.
• Keywords: Hiking, human-nature relations, slow technology, personal data archives, ecological sensibility, metadata, long-term use, first-person study, unobtrusiveness, reflective design.

Background and Problem

• Problem / challenge: Current hiking technologies focus on performance and efficiency, often neglecting deeper human-nature connections and reflective practices. Few examples exist of long-term design artifacts that foster ecological awareness and self-reflection through personal data.
• Significance: Understanding how technology can support lifelong practices like hiking is crucial for designing systems that promote ecological sensibility, self-reflection, and human-nature connectedness.
• Motivation and related work: Prior research highlights the benefits of time spent in nature and the potential of technology to mediate human-nature relations. However, concerns about obtrusiveness and the lack of long-term studies leave gaps in understanding how technology can foster reflective, slow interactions with personal data.

Solution

• Proposed approach: Capra—a system combining a wearable camera (Collector) and a home-based exploration device (Explorer) to capture and revisit hiking experiences through metadata filters (time, altitude, color).
• Novelty:
  1. Demonstrates how a slow, metadata-driven archive can support evolving self-reflection and ecological awareness.
  2. Provides a rare, multi-year case study of long-term engagement with a personal data system.
  3. Explores how unobtrusiveness can be redefined as a relational and temporal quality.
  4. Highlights the emotional and interpretive dimensions of living with a personal data archive.
• Procedure and key techniques:
  • The Collector captures timelapse images with metadata (time, altitude, color) during hikes.
  • The Explorer enables users to revisit hikes through metadata filters, fostering reflection and ecological awareness.
  • A longitudinal first-person study with three researchers (2020–2025) documented experiences, analyzed through thematic coding and narrative vignettes.

Results

• Concrete findings:
  • Capra fostered ecological sensibility by encouraging users to notice subtle environmental details (e.g., soil textures, seasonal changes).
  • Metadata filters (time, altitude, color) enabled unique ways of exploring personal archives, linking past and present hikes.
  • The system supported reflective practices, such as creating intentional timelapse markers and anticipating future archive contributions.
• Advantage over baselines:
  • Unlike traditional hiking technologies, Capra emphasized long-term, reflective engagement rather than performance metrics or real-time optimization.
  • The metadata-driven archive allowed for emergent, interpretive connections across hikes and life stages.
• Experiments / evaluation:
  • Conducted a multi-year first-person study with three researchers using Capra across diverse hiking contexts and life stages.
  • Data included journals, annotated images, and bi-weekly discussions, analyzed through open and axial coding.
• Limitations and future work:
  • The study's reliance on the researchers' own experiences limits generalizability.
  • Future work will involve participatory methods with diverse outdoor enthusiasts to explore broader perspectives.
  • Emotional and interpretive challenges of personal archives (e.g., resurfacing past relationships) require further design considerations.

Summary

This paper presents Capra, a system designed to capture and revisit hiking experiences through metadata-driven archives, fostering long-term reflection and ecological awareness. A multi-year first-person study revealed how Capra reshaped users' human-nature relations, supported reflective practices, and mediated personal life histories. The findings highlight the potential of slow, unobtrusive technologies to deepen human-nature connections and reorganize selfhood over time. Future work will explore participatory approaches to extend these insights to more diverse user groups.
