Research Background and Issues

• Problems and Challenges:

  • Maintaining long-distance intimate relationships remains a challenge that traditional communication tools cannot fully address, especially in the context of aging populations and significant physical separation.
  • Many current emotional communication device designs are complex and lack long-term evaluations, limiting a comprehensive understanding of their effectiveness and user experience.
  • Additionally, many existing devices are more suited for romantic or spousal relationships, often neglecting other intimate relationships such as those between parents and children.

• Significance of the Research:

  • Bridging the impact of distance and time differences on maintaining intimate relationships is a critical focus in HCI (e.g., in the context of isolation during COVID-19).
  • This study provides valuable first-hand observations on the long-term use of a simple, DIY emotional communication device.

• Motivation and Related Work:

  • This project was inspired by the sense of isolation brought about by the pandemic, leading to the development of a DIY device, Light Touch, to support simple communication.
  • In a broader context, the paper reviews related research in the field of emotional design, including early Media Spaces, emotional communication devices (e.g., the "remote lamp" project), and applications of autoethnographic design.

Proposed Solution

• Proposed Solution:

  • Light Touch is a simple IoT device that enables remote communication between two devices using colored light signals. Specifically, one user can select a color via touch and send it to the other device, with the light fading out over several hours.
  • The design aims to provide a minimal yet effective means of emotional expression, emphasizing simplicity and suitability for long-term use.

• Innovative Features:

  • The device focuses on minimizing communication content (using only colored light) while employing a fading light feature to create a sense of semi-synchronous and sustained attention.
  • The design offers open-ended customization options, allowing users to personalize the hardware and appearance according to their needs.
  • The system prioritizes simplifying technical operations for users, such as pre-configured WiFi settings, easy debugging, and maintenance.

• Implementation Steps and Technology:

  • The hardware architecture was built using ESP32 and sensors, enabling basic communication input and output.
  • Software design includes automatic WiFi connection, LED light fading mechanisms, and data updates between paired devices.
  • The system was released as a DIY product, accompanied by detailed construction and installation guides.

Research Outcomes

• Specific Findings:

  • The author provided in-depth first-hand accounts of over two years of use with their mother, covering initial construction and setup, daily usage patterns, troubleshooting technical issues, and resolving major breakdowns.
  • Overall findings indicate that even simple mutual light signals can be highly effective in maintaining emotional connections. For a mother-child relationship spanning an eight-hour time zone difference, Light Touch offered a low-pressure, high-value form of communication through simple actions.

• Comparative Advantages Over Existing Solutions:

  • Unlike other emotional communication designs that emphasize content richness or complex interactions, Light Touch's simplified design is well-suited for intimate familial relationships with a strong emotional foundation.
  • The addition of fading light distinguishes it from many traditional "notification-style" devices, offering greater dynamism and symbolic meaning.
  • Under an open design framework, Light Touch can be easily replicated and modified by ordinary users, enhancing its accessibility.

• Experiments and Evaluation:

  • Detailed documentation of the two-year usage dynamics between the author and their mother: average daily light signal exchanges, the symbolic meaning of light messages, and the impact of time differences and daily routines on device usage.
  • Exploration of device features, such as color selection, minimalist interaction design, and fading light signals, and how they enhance the naturalness of emotional connection in human-computer interaction.
  • The study provides high-detail, long-duration observations of a small user group (n=2), filling a gap in long-term practice data for emotional communication.

• Limitations and Future Directions:

  • The study is based on a case analysis of the author's relationship with their mother, limited to a small sample size, which may not generalize to broader applications.
  • The applicability of the device to other types of intimate relationships (e.g., friends, romantic partners) remains speculative and requires further empirical research.
  • Future directions include exploring patterns of technological functionality and relationship adaptation, conducting more diverse user experiments, and investigating the potential for more complex device features.
