Hall co-created a real-time interactive media stage play named Sayion in 2015. They received praise all
over Taiwan and they worked together again for their brand new
interdisciplinary play, Sayion II, in
2018. Other than the upgrade of technical devices, the plot is also different
from Sayion, which is about the story
of Taiwan. Sayion II has a broader
perspective and is constructed with three stories. These stories look
independent at first, but they actually bring up the questions about the modern
society. They intrigue us to think where we should go and how to live in this
world to make our significant moments valuable and unforgotten. The dancer flied
high above the stage and the colorful and brilliant background implies the
people who feel lost when they realize they can never catch their own selves.
The true freedom is the key to listen to your heart and discover what is deep
inside your heart.
I am honored and
appreciate the invitation from Hsin-Chien Huang, the winner of Best VR
Experience Golden Lion Award of Venice Film Festival. He gave me the
opportunity to collaborate with various experts – visual artist AKIBO, the
director, Chieh-hua Jeff Hsieh, of 2009 World Games in Taiwan and the
choreographer Li-Chuan Lin, the former chief dancer of Cirque du Soleil Billy
Chang, pianist Chia-Hiu Lu, and the digital platform IF Plus. The project contains
the first three chapters in the second story of Sayion II.
Theater means the live performances are created through applied science or
technology. The content of New-media Theater differs from each other according
to the transmitted information through technological devices. The media that
influence the content the most are motion pictures and still images. It is hard
to pre-output these images so the real-time synthesis and rendering through
computer software are usually applied to the performances. We not only had a
breakthrough of the imaging technology but also used motion capture system for
real-time motion detection.
MVN Motion Tracking is an inertia motion
capture system which can capture the six degree of freedom of human body and
bones in real-time.
The dancers wore MVN’s motion capture suit
during the whole performance. The dancers can freely interact with the world,
such as spreading particles and disturbing fluid, in the virtual environment
due to the linking between the motion tracking system and Unity. After
receiving data from the performers, Motions like lifting feet or swaying arms
can all be analyzed by the system. These analyses broaden the range of
interaction and the dancers are able to throw out photospheres by waving, grow
trees by lifting feet, or turn the starry sky by waving hands clockwise.
Realtime VFX - Particle System - 2D Fluid Simulation
We developed two VFX systems –Realtime GPU
Particle System and Realtime Fluid Simulation System – as a real-time
assistance for simulating and reverting to the original art settings.
The Particle System is a great help on immediately
constructing a world based on particles in Unity. Then, the system is able to
simulate complicated physical actions, such as the wind, smoke, water, and
explosion, through algorithms and creates a dynamic and immersive atmosphere.
Fluid Simulation System focuses on the more detailed algorithms of fluid
simulation. It makes the mixing process of fluid more meticulous and
With the help of MVN
system and the mentioned systems, the dancers can indirectly affect the visual
effects by their movements and postures during the performance.
story of the project is that we have to look into our hearts and create our own
world step by step when facing the unknown darkness. We gradually became
someone else and lost our confident self. Playing, chasing, fighting, and
retreating – we can no longer find our beliefs in the resplendent colors. As
time goes by, we gain life experiences and finally realize what we have lost is
In my hazy memory, I’m blind but sensitive
in the dark. I’m not afraid and I want to get closer.
The power of sound
evokes the journey. It’s a sound like summon from the outer and like the
calling deep in the heart
