C Programming (C프로그래밍)

for 1st year students

  • First principle: Ensure all students do not lose interest until the end of the semester.

  • Start each lesson with review of prev. lesson & brief overview of today’s lesson.
  • Give time for hands-on coding practice and questions between each sub-topics.
  • Daily assignments are given 10-15 mins before the end of each lesson and recommended to be submitted within the lecture hours.
  • Give prompt feedback for prev. daily assignments in the next lesson.

  • For frequent assignments and prompt feedback, I developed PACERs (Programming Assignments Compiling, Executing, and Reporting system) script.

Performance-Based Biped Control using a Consumer Depth Camera

Eurographics 2017



A user controls a physically simulated character by moving his or her body parts. Top: The input depth data of user poses. Bottom: The simulated character imitating the user’s actions.

Abstract
We present a technique for controlling physically simulated characters using user inputs from an off-the-shelf depth camera. Our controller takes a real-time stream of user poses as input, and simulates a stream of target poses of a biped based on it. The simulated biped mimics the user's actions while moving forward at a modest speed and maintaining balance. The controller is parameterized over a set of modulated reference motions that aims to cover the range of possible user actions. For real-time simulation, the best set of control parameters for the current input pose is chosen from the parameterized sets of pre-computed control parameters via a regression method. By applying the chosen parameters at each moment, the simulated biped can imitate a range of user actions while walking in various interactive scenarios.
