"Haptics On-Demand": A Survey on Encountered-Type Haptic Displays
IEEE Transactions on Haptics
|February 23, 2021
Summary
Encountered-Type Haptic Displays (ETHDs) offer unique haptic feedback in virtual simulations by using a tangible surface. This survey analyzes ETHD research, definitions, hardware, and applications to guide future advancements.
Area of Science:
- Human-Computer Interaction
- Robotics
- Virtual Reality
Background:
- Current haptic devices often use actuators constantly in contact with the user.
- Encountered-Type Haptic Displays (ETHDs) provide feedback via a tangible surface positioned for user interaction.
- This approach differs from traditional, always-on haptic feedback systems.
Purpose of the Study:
- To comprehensively review and analyze research on Encountered-Type Haptic Displays (ETHDs).
- To establish a formal definition and taxonomy for ETHDs and their hardware.
- To explore haptic perception, interactions, and applications within the ETHD field.
Main Methods:
- Systematic literature review of ETHD research.
- Analysis of definitions, historical development, and hardware classifications.
- Examination of haptic feedback mechanisms, user perception, and applications.
Main Results:
- A formal definition for ETHDs is proposed.
- A taxonomy for classifying ETHD hardware is presented.
- Analysis of haptic feedback strategies and applications in existing literature.
Conclusions:
- The survey provides a structured overview of the ETHD field.
- Identified research gaps and areas for future investigation.
- Aims to stimulate further research and development in encountered-type haptic technology.

568
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
