Real human walking motion is reconstructed employing a developed motion capture system and the obtained 3-D human model is projected into a real space through a see-through type head mounted display. The realized environment is referred to as a mixed reality space. The developed system not only provides smooth motion of the virtual human, but also solves the occlusion problem among the real objects in front of the observer and the projected virtual human. The performed experiment gives satisfactory results.","PeriodicalId":301855,"journal":{"name":"Proceedings of the 41st SICE Annual Conference.

A mass measurement system using the self-excited oscillation of a nonlinear system is developed.

One is based on energy control, and the other is based on a linear feedback control so that the poles of the closed-loop system are assigned to make the pendant position unstable and the upright position stable. Two different linear feedback control laws are used in the course of the swing-up and balancing of the acrobot at the upright position. The proposed strategies are evaluated by the simulation.","PeriodicalId":301855,"journal":{"name":"Proceedings of the 41st SICE Annual Conference.

We derive a new solvability condition of the problem in the form of a linear matrix inequality (LMI) condition adding a rank condition. The condition is still nonconvex due to the existence of the rank condition. However, it can be checked approximately with the alternating projection method, and the approach might be more efficient than the existing methods from the viewpoint of computation.","PeriodicalId":301855,"journal":{"name":"Proceedings of the 41st SICE Annual Conference.
