From Overload to Convergence: Supporting Multi-Issue Human–AI Negotiation with Bayesian Visualization
Mehul Parmar & Chaklam Silpasuwanchai · CHI 2026

Addresses cognitive overload in multi-issue human–AI negotiation by introducing a Bayesian visualization framework that helps users converge on agreements — bridging HCI, decision theory, and AI transparency.

Impact of User Mobility on Attentional Tunneling in Handheld AR
Mehul Parmar & Chaklam Silpasuwanchai · pp. 1–6 · 2023

Investigated how physical mobility affects attentional tunneling in handheld augmented reality. A 2×3 study comparing stationary vs. walking postures showed walking significantly amplifies the tunneling effect — with implications for safer AR interface design.

A Comprehensive Study on Interaction Fidelity and Carry-over Effects in Virtual Reality Environment
Alam, Sakib Bin; Lameesa, Aiman; Parmar, Mehul; Dasgupta, Paramik; Nipattananchock, Thanagid; Ferdoush, Mohammad Shahinur · pp. 257–263 · 2024

Investigates carry-over effects when users transition between high and low fidelity VR environments. Using H-L-H and L-H-L fidelity conditions, the study reveals that carry-over effects significantly impact performance and motion sickness levels — with implications for VR training simulation and user experience design.
