Successful Conclusion of HumOmni 2026 Challenge: Breakthroughs in Human-Centric Omni-Model Evaluation

We are pleased to announce the successful conclusion of the HumOmni 2026 Challenge, co-organised by PolyU COMP, Huawei, and Peking University from April to July 2026. The competition was the first benchmark dedicated to Human-Centric Omni-Model Evaluation, focusing on contextualised affective speech generation and proactive multimodal interaction in realistic environments, attracting nearly 25 teams from Hong Kong, mainland China, and the United States.   The challenge featured two tracks designed to develop next-generation models in two key areas: Track 1: Empathy-Aware Speech Evaluation (EmpathyEval) – Evaluates how multimodal systems understand human context and paralinguistic cues to produce appropriate affective spoken responses. Track 2: Proactive Multimodal Interaction (ProactivEval) – Assesses proactive multimodal systems on their ability to decide when to respond and what to say during streaming video understanding.   The award ceremony was held on the PolyU campus on 28 August 2026, bringing together researchers, industry leaders, and students for an engaging program featuring keynote speeches, winning team presentations, recruitment opportunities, and the award presentation. Distinguished speakers delivered insightful talks on:   “From world reconstruction, generation, to interaction” by Dr QI Xiaojuan, Associate Professor at The University of Hong Kong and a member of the Deep Vision Lab. “Multimodal Large Language Models with Ascend NPUs” by Dr HONG Lanqing, Senior Researcher at Huawei Noah's Ark Lab, Hong Kong.   During the sharing sessions, winning teams presented their novel methodologies, including our MPhil student, LAM Ping Him, who proudly secured two awards: 1st Place in Track 2 (ProactivEval) and 2nd Place in Track 1 (EmpathyEval). Ping Him successfully developed lightweight AI solutions across two distinct challenges:   Track 1 - Voice Empathy Evaluation Built an audio-focused system that evaluates emotional nuance in spoken conversations rather than relying on text. Using WavLM-large to extract voice patterns and track delivery metrics over time, the model accurately judges empathy from tone, pace, and warmth.   Track 2 - Proactive Video Commentary Created a training-free filtering framework that enables an AI assistant to speak only when relevant visual changes occur. It uses a Perception Gate to skip static frames and cut compute costs, paired with a Prompt Ensemble to analyse new scenes from multiple perspectives.   His outstanding performance highlights the Department's commitment to fostering research excellence and innovation in AI and showcases the strength of our students on the international stage.   Click here to read more about HumOmni 2026.

AI-Powered Mock Interview Platform Developed by COMP Team Wins Champion at AIREA 2nd International Competition on AI in Education 2026

We are proud to announce that a COMP team has won the Champion award in Stream 2 - “Challenge”, at the 2nd International Competition on AI in Education 2026, organised by the Artificial Intelligence Education and Research Alliance (AIREA) of The Education University of Hong Kong.   Winning Project: PolyInterview: A Multi-Agent Interview Practice Platform for Communication Education   Team Members Chen CHEN (MPhil Student) Zijian WANG (Research Assistant) Jianing YIN (MPhil Student) Xiaoyun LIU (PhD Student) Dr Zhiyuan WEN (Research Assistant Professor)   Abstract: Preparing for job interviews is important for securing desired positions, yet realistic practice remains difficult to access: real interviews are infrequent, expert mock coaching is costly, and self-practice offers neither adaptive dialogue nor structured assessment. Existing systems typically address only parts of this need through fixed question sequences, limited communication channels, or feedback with little supporting evidence. We present PolyInterview, an LLM-based platform for immersive mock interview practice with comprehensive multimodal assessment. PolyInterview uses the target job description and CV to generate questions tailored to the role and candidate, conducts multi-turn spoken interviews with a lip-synced digital human interviewer that asks answer-aware follow-up questions, and evaluates response content, vocal delivery, and non-verbal behavior. Four parallel evaluators produce 13 behavior-level features that are aggregated into 10 assessment aspects and two competency tracks. Guided by the KSA and STAR frameworks, the report links each score to behavioral evidence and actionable recommendations. Its current all-account snapshot contains 101 accounts, 1,564 interview sessions, 7,665 generated questions, and 1,422 five-stage question sets. Generated questions are more closely aligned with their matched job description than with cross-role job descriptions in 93.7% of sessions. An evaluation by ten experts found strong question plans and actionable feedback.   Online Platform
