Firefly Dimension is developing ultra-wide field-of-view, stand-alone, and cost-effective Mix Reality headsets for enterprise-focused applications. My passion and responsibilities:- Visual-inertial fusion and the computer vision algorithm development- Calibration method and fixture design- Algorithm implementation in Android on the framework and native level- Android graphics pipeline customization to achieve Asynchronous Time Warping- Kernel driver and hal/hidl development for sensor modules- Product design and rapid prototyping

Develop universally mountable HUD and AR modules for eye-wears.(C++) Computer vision, stereo visual SLAM(C) Embedded firmware, inertial sensor based head-tracking algorithm(Solidworks) Product design, product management, concept development, prototyping(Android) mobile app, BLE, GPS

Keywords: MPC, ROS, Matlab, object avoidance, Kalman filter, C++, C#, JuliaDeveloped and validated a Model Predictive Controller (MPC) obstacle avoidance and lane keeping algorithm on a test vehicle;Implemented Extended Kalman filter with kinematic bicycle model using Julia on Robot Operating System;Designed a hardware-in-the-loop (HIL) simulator to rapidly evaluate the performance of autonomous driving algorithms with minimal cost and risk;Visualized the test process using Unity and Oculus Rift Virtual Reality headset to allow the study in human-vehicle interaction.Developed a stand alone scenario editor running independent of Unity development environment to allow easier scenario setup, obstacle placement, and parameter tuning.

Keywords: Microcontroller, LabVIEW, PID tuning, inverse pendulumDesigned and built a self-balancing, two-wheel robot to follow the lane with desired speed.Implemented and tuned balancing, speed, and steering PID controllers on real-time layer of a NI MyRio.Programmed in LabVIEW for data acquisition of inertial measurement unit, line-scan camera, encoder.Fused gyroscope and accelerometer measurements using complementary filter and posteriori observer.Designed a graphic user interface to allow manual control and stream back measurements from the mounted camera.Designed and assembled robot frames with AutoCAD Inventor and 3D printer.
