Document Information

• Subject Area: Human-Computer Interaction and Smart Home Control
• Keywords: Textile interface, smart textiles, slider design, embroidery, non-wearable devices, design recommendations, eyes-free interaction, continuous input

Research Background and Issues

• Identified Problems or Challenges: Previous studies have primarily focused on technological development, with limited exploration of the physical design characteristics of textile controllers, particularly the impact of slider shape, depth settings (raised/recessed), and tick mark distribution on user interaction.
• Significance: Smart homes require intuitive, comfortable, and eyes-free interaction modes. Textile controllers can be integrated into home environments, offering convenient and low-disruption operation methods (e.g., controlling lighting or volume). However, the impact of such interface designs on user experience remains unclear.
• Research Motivation and Related Work: A literature review reveals that the manufacturing methods and application scenarios of textile touch interfaces are sufficiently broad, but there is a lack of research on specific shape designs and user performance. Guideline studies have largely focused on wearable devices, with limited coverage of non-wearable applications such as furniture.

Solution

• Methods and Innovations:
  • Conducted two user studies on textile sliders, focusing on basic form factors (e.g., shape, surface height) and the number and distribution of tick marks.
  • Created non-functional prototypes to eliminate interference from technical embroidery used for recognition, evaluating only the impact of the physical design of sliders on tactile user experience.
• Key Techniques and Methods:
  • Used embroidery techniques to create raised, recessed, and flat slider forms.
  • Designed both user experiments to enforce "blind testing" (without relying on vision), evaluating the intuitive usability and positioning accuracy of sliders.
  • Slider design parameters included shape, tick mark design, and spacing (e.g., equidistant, irregular distribution).
  • Combined five-point Likert scale ratings with quantitative experimental metrics (accuracy, operation time, etc.) to analyze user preferences.

Research Findings

• Specific Findings:
  • Users generally preferred recessed or raised slider designs, with recessed sliders better supporting sliding gestures.
  • Increasing the number of tick marks significantly improved positioning accuracy, with at least three tick marks required to ensure user precision.
  • Compared to standard slider shapes (rectangular), complex shapes (e.g., horseshoe) may interfere with eyes-free operation.
  • Design elements (e.g., rotated or elevated tick marks) significantly reduced the range of finger movement during positioning.
• Advantages Over Existing Research:
  • Provided empirical data on user behavior for slider design, addressing the research gap in the physical design of non-wearable textile interfaces.
  • Proposed preliminary guidelines for slider design, such as recommending recessed forms and clear tick mark layouts.
• Experimental and Evaluation Results:
  • Experiment 1 revealed the impact of shape and dimensional height on comfort and operational support: recessed sliders received the highest ratings.
  • Experiment 2 emphasized the role of tick marks in helping users quickly and accurately locate positions, with regularly spaced tick marks being the most effective.
• Limitations and Future Directions:
  • Evaluations were conducted only in a laboratory setting with static designs, without testing real-world scenarios such as the impact of dynamic feedback on user experience.
  • The influence of visual elements on slider preferences was not studied; future work could explore hybrid designs combining visual and tactile interactions.
  • Potential effects of environmental factors (e.g., material surface texture, slider orientation) on user experience require further investigation.
  • Developing functional sliders could enable research into dynamic operation modes, such as real-time slider adjustments adapting to user input.

Conclusion

This study thoroughly investigates the impact of textile slider design on user experience, particularly in eyes-free usage scenarios, and provides design recommendations through experimental findings. It offers empirical support for the growing research trend in this field. Future work could integrate dynamic, real-life environments and optimized sensory feedback to further refine textile slider designs, meeting a broader range of user needs.
