Research Background and Issues

• Identified Problems or Challenges:

  • Current research primarily focuses on the short-term use of voice assistants by older adults, with limited studies on long-term use.
  • Some studies suggest that the appeal of voice assistant features (e.g., music, reminders) may diminish as the novelty wears off.
  • The structured command system and limited functional value of voice assistants compared to other technologies may hinder their adoption among older adults.
  • There is a lack of understanding regarding how older adults overcome barriers and perceive utility after long-term use of voice assistants.

• Significance of the Issue:

  • Voice assistants are considered a more user-friendly technology for older adults due to their hands-free mode and natural language interaction, offering potential support in daily life, health management, and even social interaction.
  • Exploring how to optimize the design and learning process of voice assistants can promote their adoption among older adults and support their continued digital engagement.

• Research Motivation and Related Work:

  • Motivation: To understand how older adults discover the utility of voice assistants and overcome usage barriers after long-term use, with the goal of proposing design improvements.
  • Related Work: Previous studies have focused on evaluating the functionality of voice assistants during short-term use by older adults, revealing challenges such as difficulty remembering commands, limitations in language interaction, and the gradual abandonment of certain features.

Proposed Solution

• Research Methods:

  • Conduct semi-structured interviews with a group of older adults who have used Amazon Alexa for over a year, investigating their learning processes, daily usage, and perceptions of voice assistant interaction capabilities.
  • Use a combination of methods to organize and analyze data, including open coding and thematic analysis.

• Innovative Contributions:

  • The study focuses on long-term users rather than first-time or short-term users, addressing a gap in the current literature.
  • Provides empirical data on the training process and sustained usage patterns of voice assistants.
  • Proposes specific design recommendations tailored to the unique needs of older adults' living environments (e.g., long-term care communities).

• Implementation Steps:

  1. Collaborate with companies providing voice assistants to recruit participants through their training programs.
  2. Conduct one-on-one interviews with participants, covering topics such as learning processes, daily usage, and perceptions of voice assistants.
  3. Code and analyze the data to extract user experiences and insights.

Research Findings

• Specific Findings:

  • Users learned to use Alexa primarily through paper-based brochures and live demonstrations, gradually mastering skills through trial and error.
  • Voice assistants were frequently used to support daily tasks (e.g., alarms, weather inquiries), enhance mood (e.g., through music and meditation), and provide cognitive stimulation (e.g., games and information searches).
  • Participants recognized the value of voice assistants in companionship and conversational functions, despite the limited conversational capabilities.

• Advantages Compared to Existing Solutions:

  • Unlike previous studies where voice assistant features were abandoned as their novelty faded, users in this study successfully integrated voice assistants into their daily lives, demonstrating the potential for long-term use.
  • Specific features (e.g., community menu and activity inquiries) were tailored through custom skill design to better meet the needs of older adults.

• Experimental or Evaluation Results:

  • The training and exploration process played a critical role in helping older users discover voice assistant functionalities and overcome the limitations of voice commands.
  • Voice assistants contributed to improving convenience in daily life and alleviating loneliness, although the learning curve for complex commands remained a barrier.

• Limitations and Future Directions:

  • The study primarily focused on voluntary long-term users, potentially excluding older adults who abandoned voice assistants.
  • Future work could expand to more diverse living environments (e.g., older adults living alone) and explore the potential of voice assistants in specific areas such as cognitive support and social activities.
  • Further research could investigate improvements in support for complex multi-step commands or deep conversational interactions, while enhancing personal privacy settings and adaptive design.
