Research Background and Problem

• Problem or Challenge:

  • Current interface designs for breathing feedback primarily focus on visual or auditory modalities, with limited exploration of tactile feedback, especially interactions based on deep touch pressure.
  • While Deep Touch Pressure (DTP) has been applied in treating sensory processing disorders (e.g., anxiety or autism), it has rarely been incorporated into interactive design research, and existing commercial products lack interactivity.
  • Research on the aesthetic or experiential qualities of shape-changing interfaces in breathing interaction is underdeveloped, restricting the expansion of the design space.

• Research Motivation: To investigate how dynamic deformation feedback and tactile interaction can enhance users' awareness of their body and breathing, and to explore and expand the practical and aesthetic potential of deep touch pressure in breathing interaction design.

• Related Work:

  • Breathing interaction designs often use auditory and visual feedback (e.g., augmented reality meditation training) or vibration feedback, but these health and meditation applications are often simplistic, overlooking the complexity of bodily perception.
  • HCI research related to dynamic shape-changing materials mainly focuses on technical feasibility, with limited exploration of the experiential value of shape-changing interactions with the body.

Solution

• Proposed Method or Solution:

  • This paper designs an interactive experimental system combining dynamic deep touch pressure feedback and breathing sensing.
  • Based on dynamically deformable airbag components, real-time breathing monitoring, and user experience exploration, an experimental wearable device was developed to simulate breathing interaction experiences through deep touch pressure.

• Innovations:

  • Explores the application of shape-changing interfaces in interactive deep touch pressure, introducing an aesthetic interaction dimension to breathing feedback;
  • Proposes key design concepts in breathing interaction, including "symmetry and asymmetry," "synchrony and asynchrony," and the "balance of leading and following";
  • Creates a deep sensory interaction experience aligned with users' breathing rhythms, referred to as "Breathing Correspondence."

• Implementation Steps and Key Technologies:

  • Phase 1: Initial design exploration using airbag pressure layering technology (including individual in-depth studies and collaborative workshops).
  • Phase 2: Development of wearable prototypes integrating airbags and breathing sensors into the device. Wearers experienced different breathing patterns through various postures and scenarios.
  • Breathing and Deformation Control Framework: A sensor-based breathing detector connected to an Arduino control unit adjusted pressure in real time based on breathing data.
  • User Testing: Experimental daily use over three weeks, with changes recorded through logs and subjective perception (autobiographical user experience data recording method).

Research Outcomes

• Specific Results:

  1. New Textures and Interaction Experiences:

     • Applied symmetrical and asymmetrical deep touch pressure to help users focus on different body parts and their connection to breathing.
     • Supported various breathing patterns (e.g., alternating diaphragmatic and chest breathing) through deep touch pressure design.

  2. Interaction Feedback Types (Synchronous vs. Asynchronous):

     • Synchronous feedback: Enhanced users' awareness of their breathing rhythm;
     • Asynchronous feedback: Disrupted habitual patterns to encourage users to explore alternative breathing methods.

  3. Breathing Leadership and Following:

     • Introduced the "Breathing Correspondence" design concept, balancing user-led and system-influenced interactions in deep touch pressure.

  4. Long-Term Perception and Learning Effects:

     • Users reported improved breathing control and bodily awareness, with some experiences transferring to daily life.

• Advantages Compared to Existing Solutions:

  • Expanded the aesthetics and interactivity of shape-changing interface design;
  • Enhanced the dimensions of breathing feedback through tactile interaction, surpassing the limitations of traditional health-related interactive feedback.

• Experimental or Evaluation Results:

  • Long-term autobiographical experiments demonstrated that this interaction method enhanced users' breathing awareness;
  • Different feedback rhythms and airbag pressure patterns significantly influenced users' perception of breathing, validating the potential and challenges of "breathing aesthetics."

• Limitations and Future Directions:

  • Limitations:
    • Current experiments primarily involved researchers as participants, requiring broader population testing;
    • Practical issues such as acoustic interference (e.g., noise from air pumps).
  • Future Directions:
    • Customizing designs for specific medical or health scenarios (e.g., anxiety, autism);
    • Enhancing social interaction features (e.g., collaborative scenarios with multi-user breathing synchronization).
