The development of advanced interactive systems necessitates a deep understanding of human factors, as demonstrated by research into haptic devices. For instance, the study by Bilgincan and Dede (2010) explored the reconfiguration of a haptic mechanism to optimize gravitational effects and enable point-type contact, thereby enhancing user feedback. This highlights the importance of considering mechanical design choices that directly influence the user's sensory experience and interaction fidelity.
