+Identifies key challenges and promising future research directions.

Limitations

The review highlights a lack of long-term studies and standardized testing, meaning that the full impact and optimal implementation of haptic feedback may not yet be fully understood.

Reliability & validity

The reliability and validity of findings in this review are dependent on the quality and rigor of the individual studies examined. The lack of standardized methods for characterizing sensations and benchmarking performance across studies may limit the overall generalizability and comparability of results.

Think critically

Given the identified gaps in long-term evaluation and standardized methods, how can designers proactively develop and test haptic feedback systems that are both effective and reliably measurable?

Design Principles

"Sensory feedback is integral to effective motor control and learning; design systems that provide rich, context-aware haptic information to users."

For designers of assistive and rehabilitative technologies, understanding how haptic feedback influences user perception and performance is crucial. This insight highlights the potential for richer, more intuitive human-machine interactions that can accelerate recovery and improve the user experience.
