Work experience
- Oct 2019 - Present: HCI Researcher at Huawei HMI Lab
- Been project manager for 3 VR-related projects that led to publications to top conferences, worked hands-on on development (C# & Java), user experiment design, paper writing, etc.
- Led a R&D project of designing an input device for remote interaction with large displays, worked on quick prototyping, users studies, and patent filing.
- Led a R&D project of touchscreen input classification using deep learning (Python & TensorFlow).
- Applied for 5+ HCI-related patents.
- Sep 2014 - Sep 2019: Research Assistant at VVISE Lab, Simon Fraser University
- Used Unity engine, C#, and GPU programming to develop two novel interaction techniques for positioning of 3D objects, which profoundly outperformed industry standard approach.
- Adapted my techniques to virtual reality (VR) with HTC Vive and Oculus Rift. Analyzed different input devices for in VR.
- Conducted multiple user studies. Used Python, JMP, and SPSS to analyze the data.
- Presented my work with talks, demos, and posters at multiple academic conferences.
- Aug 2018: Student Volunteer at ACM SIGGRAPH 2018
- Worked 25 hours on various shifts. Helped attendees with a warm smile.
- Sep 2013 - Aug 2014: Research Assistant at York University
- Implemented an efficient 3D manipulation technique.
- Compared text entry performance of different input modes with user studies, with and without auto-correction.
- Sep 2011 - Dec 2012: Research Assistant at Western University
- Used machine learning and computer vision algorithms to automatically detect and classify epilepsy lesions from digitized MRI images. Achieved 93% accuracy. Programmed with C++ and MATLAB.
- Classified different human actions from video sequences with machine learning methods using MATLAB.
