In detail, following demonstrators were presented:
- Bra4Vit – Phoneless step- and breath-adherent auditory breathing guidance in running via smart garments: Severin Bernhart unveiled a phoneless wearable that tracks stride and breathing rates. Controlled breathing enhances joyful and performance-boosting running rhythm that is supported using targeted audio cues via connected headphones. Powered by warp knitted textile sensors and energy efficient on-edge algorithms, the system delivers low-latency feedback guidance. Treadmill tests prove promising user experiences and field studies upcoming.
- Into the Rhythm — Sound Guidance for Synchronizing Breath and Steps in Running: Exploring Sonic Support for Locomotor-Respiratory Coupling: Vincent van Rheden presented a field-tested system that uses sound cues to help runners align breathing with their stride rhythm. With 15 recreational runners evaluating the approach outdoors, results showed solid satisfaction and clear benefits when fatigue set in. The study confirms sound as a promising modality for real-world LRC guidance and introduces five design recommendations for future adaptive, personalized systems. This research charts a path toward smarter, more intuitive running experiences that amplify both efficiency and enjoyment.
- GestureSock++ — Using Toe Gestures as Hands-Free Input While Cycling: Redefining On-Bike Interaction with Smart Toe-Based Control: The GestureSock++ demo, led by Vincent van Rheden and collaborators, showcased a cycling sock enhanced with textile pressure sensors that enables subtle toe gestures as input. Designed for continuous or discrete control, the system demonstrates how cyclists might interact with digital content without relying on hands, screens, or traditional controllers. Visitors could try the concept through a playful game, revealing the potential of toe-based interaction for safer, more intuitive on-bike experiences across real-world, AR, and VR settings.
- Into the Zone — Ambient LED Goggles for Heart-Rate Zone Awareness in Running: Smart Goggles Deliver Glanceable Heart-Rate Feedback for Runners: Ege Çelikgöğüs, Vincent van Rheden, and Alexander Meschtscherjakov introduced LED-equipped goggles that help runners maintain their target heart-rate zones without relying on wrist-based displays. An integrated ambient light strip communicates zone status either through color-coded reflections or corrective cues indicating whether the runner is on target. The demo allowed attendees to experience both feedback modes firsthand, highlighting a promising alternative to conventional tracking devices and paving the way for more seamless, distraction-free physiological feedback during training.
