Haptic Relocation Away From the Fingertip: Where, Why, and How

Area of Science:

• Human-Computer Interaction
• Robotics
• Wearable Technology

Background:

• Tactile haptic devices typically render feedback to fingertips and hands.
• Recent trends explore alternative body locations (e.g., wrist, arm) for haptic feedback due to wearability and application needs.
• Haptic relocation is a novel concept where expected fingertip feedback is rendered elsewhere.

Purpose of the Study:

• To investigate design choices for wearable haptic devices enabling haptic relocation.
• To explore considerations for different body locations, applications, and actuator selection in haptic relocation.
• To provide guidance for engineers and researchers developing alternative haptic rendering solutions.

Main Methods:

• Literature review of existing approaches and design choices for wearable haptic devices.
• Analysis of haptic relocation scenarios, including fingertip-based feedback rendered to alternative sites.
• Discussion of actuator selection and body location considerations for effective haptic relocation.

Main Results:

• Identified key design considerations for wearable haptic devices in haptic relocation.
• Explored the potential of alternative body locations for rendering complex touch-based information.
• Highlighted the importance of actuator selection and application-specific design.

Conclusions:

• Haptic relocation offers promising alternative haptic rendering solutions, particularly when hands are occupied or unavailable.
• Further research is needed to address challenges and optimize design choices for effective haptic relocation.
• This work guides the development of innovative wearable haptic systems for diverse applications.
