Emerging Technologies Shaping Future HCD in VR andAR Engineering

Wzmacnianie czujności Feedback: Haptics andBeyond

Haptic feedback is advancing beyond simple vibration motors. Companies like HaptX and Teslasuit offer gloves and full-body suits that provide realistic tactile sensations — from the resistance of a button press to the feeling of a tool handle. For engineering training, this is transformative: learning to torque a bolt or wield a welding torch in VR becomes far more transferable when the user feels the correct amount of resistance. Haptic feedback also improves collaboration, allowing remote users to perceive handshakes or object hand-offs. Nevertheless, these devices are still expensive, bulky, and require calibration. Human-centered design must balance fidelity with practicality, ensuring that the haptic feedback does not overwhelm the user or introduce new ergonomic problems.
