# Functional Adaptation and Emergent User Solutions in Domestic Tasks: Supporting Aging in Place Through a Field Study on Design Challenges Among Older Adults in Chile

## TL;DR

This study explores how older adults in Chile adapt their daily tasks to maintain independence at home, offering insights for inclusive product design.

## Contribution

The study identifies emergent user solutions and adaptation strategies among older adults for inclusive product design.

## Key findings

- Older adults use temporal redistribution and spatial reorganization to manage domestic tasks.
- Informal tool use and social support are common adaptation strategies.
- User-driven solutions can inform low-cost redesign of everyday objects.

## Abstract

Maintaining quality of life through functional autonomy is crucial for supporting aging in place. While assistive technologies and architectural adaptations have received significant attention, there is limited knowledge on how older adults independently adapt domestic routines using everyday household products. Background/Objectives: This study aimed to explore how functionally independent older adults manage key domestic tasks and to identify user-driven adaptations that could inform inclusive product design. Methods: We conducted a qualitative field study involving non-participant observations and in-depth case studies with 20 older adults aged 65–85 living in urban Chile. Participants were observed while performing cooking, dishwashing, and waste disposal activities. Thematic analysis and axial coding, based on grounded theory principles, were applied to identify adaptation strategies and usability barriers. Results: Participants employed a range of adaptation strategies across tasks, including temporal redistribution of effort, spatial reorganization, informal tool use, and reliance on social support. These adaptations reflected creative and situated responses to physical and environmental constraints. Many strategies could be interpreted as emergent user solutions, offering practical insights for the inclusive and low-cost redesign of everyday objects. Conclusions: Older adults actively modify their interactions with domestic environments to preserve autonomy and functionality. Recognizing and incorporating these emergent user adaptations into product design processes can strengthen inclusive design practices, support aging in place, and inform public health strategies aimed at promoting independence among aging populations.
