Validation of Snaptics: A Modular Approach to Low-Cost Wearable Multi-Sensory Haptics

Area of Science:

• Human-Computer Interaction
• Robotics
• Biomedical Engineering

Background:

• Wearable haptic devices offer touch feedback for virtual reality, prosthetics, and navigation.
• Research-grade haptic devices are often specialized, costly, and difficult to replicate.
• A need exists for accessible, customizable haptic hardware for research and development.

Purpose of the Study:

• To introduce Snaptics, a modular platform for rapid prototyping of wearable multi-sensory haptic devices.
• To demonstrate the versatility and effectiveness of Snaptics in delivering salient haptic cues.
• To evaluate the performance of Snaptics devices in human subject experiments.

Main Methods:

• Developed Snaptics, a platform using 3D-printed modules and off-the-shelf components for wearable haptic device prototyping.
• Conducted two human subject experiments to assess haptic cue identification and task performance.
• Compared a Snaptics Vibrotactile Bracelet to a high-fidelity research-grade device in a virtual reality sorting task.

Main Results:

• Demonstrated the ability to construct functional wearable haptic devices using the Snaptics platform.
• Human subjects could accurately identify multi-sensory haptic cues delivered by Snaptics devices.
• Participant performance in a virtual reality task was comparable between low-cost Snaptics devices and a research-grade haptic wearable.

Conclusions:

• Snaptics provides a simple, modular, and cost-effective solution for prototyping wearable haptic devices.
• The platform facilitates the creation of accessible multi-sensory haptic feedback systems.
• Snaptics enables research comparable to high-fidelity systems using affordable components.
