Chapter overview:

PART I

Chaper 01: Häcka (student project #1), Introduction by Joris Weijdom and Marcel Alberts
PLMixedReality_deel1_01.avi (9:48 min)

Opening with the first student project called Häcka, an experiment with video projection on translucent screens. The performance is designed to be a loop that could potentially run forever. Because of the light situation the video camera’s have captured only a fraction of the actual piece. Have a look at the Mixed Reality project page for more information on this piece.

Next Joris Weijdom gives an introduction on the context of the evening and the Mixed reailty project. Marcel Alberts, one of the mentoring teachers, gives a more in-depth response to the interdisciplinary nature of the working process and a first reflection on the first student piece.

Chapter 02: Introduction on the research context, a definition of Mixed Reailty and why we focused on space (instead of reality)
PLMixedReality_deel1_02.avi (8:59 min)

In this chapter the research context of the researchgroup Virtual Theatre is briefly introduced and  related to the subject of Mixed Reality. Then the term Mixed Reality is explained and defined through the model of the Virtuality continuum. In the second half the problematics concerning the perception of reality is discussed.

Chapter 03: About the definition of physical and virtual space
PLMixedReality_deel1_03.avi (10:52 min)

In order to combine physical and virtual space one needs to find a common method of defining both types of spaces. First relative approaches to physical space are explored. Then more absolute mathematical systems are introduced and used to move to virtual space. At the end of the video the cycle of bringing physical objects into virtual space (digitizing) and bringing virtual objects in to the physical space is discussed.

Chapter 04: Tabula Rasa (student project #2) and reflection by Marcel Alberts
PLMixedReality_deel1_04.avi (8:52 min)

The second student project group has been researching the potential of live drawing with light on 3D objects. Although they had many ideas the end result focuses on the simple aesthetics of live drawing itself. Have a look at the Mixed Reality project page for more information on this piece. The white character head has been designed with a 3D computer program, printed out on paper and folded into an analogue 3D head. A procedure briefly explained in the end of chapter 3.

In the second half of this video Marcel Alberts gives his reflection on the piece.

Chapter 05: A virtual 3D model of the theatre (live demo)
PLMixedReality_deel1_05.avi (3:15 min)

Being able to present four student projects with intense use of seven different video-projectors and only two days to build up we decided to build the whole theater-space in the computer as a scale model to figure out the video-projector placing, screen positioning, cable lengths and sight-lines. In this short video the 3D virtual model is briefly demonstrated as an example of using a virtual model to solve problems in physical space.

Chapter 06: Theater space, Virtual Reality and the CAVE
PLMixedReality_deel1_06.avi (8:51 min)

How can a theatre-space be theoretically observed? In this video a model by Peter Eversmann is discussed as a means of observing theatre-space by looking at the structural and the usage dimensions. Thus categorizing differnet types of theatre in a two-axis model. The 3 axis Multiverse model of jospeh Pine II is briefly mentioned.

The second half of the video gives an introduction to Virtual Reality and the progression to the CAVE. Hinting to a growing need and technological development to share and combine physical and virtual space into one mixed reality.

PART II

Chapter 07: Return to sender (student project #3) and reflection by Marcel Alberts
PLMixedReality_deel2_01.avi (8:07 min)

The third student project group got fascinated by a shadow having its own life. In order to project a shadow that could be animated and at the same time have a front projection for the performer and objects was quite a challenge. Also they managed to do a simple 3D projection map on the physical cube. Have a look at the Mixed Reality project page for more information on this piece.

In the second half of this video Marcel Alberts gives his reflection on the piece.

Chapter 08: About Augmented Reality (with live demo)
PLMixedReality_deel2_02.avi (9:03 min)

This video is entirely about Augmented Reality (AR). First three important aspects are summarized about AR then a live demonstration is given of a desktop AR marker based setup. In the second half of this video attention is given to the beautifull AR project of Julian Oliver called Levelhead.

Chapter 09: More about Augmented Reality, terms and recent technology
PLMixedReality_deel2_03.avi (7:19 min)

AR related terms as; Desktop AR and Mobile AR, marker and markerless, Magic mirror vs Magic lens, are explained through examples. A brief moment is given to the consequences of OLED technology. Which brings us to the question if these recent technological developments are usable in theatre.

Chapter 10: The power of projection, 2D and 3D surfaces
PLMixedReality_deel2_04.avi (9:47 min)

The first part of this video gives an overview of projection methods on 2D surfaces through recent examples. The second half is about projection on 3D surfaces or objects. These objects can be sculptures or even buildings. The extra challenge to this method is to perspectively compensate for the angled surfaces by using so called projection mapping techniques.

Chapter 11: Cool projection mapping, but is Mixed Reality technology new (in theatre)?
PLMixedReality_deel2_05.avi (9:45 min)

Our own experiments with projection mapping is shown adding the real-time 3D aspect to this development. Also briefly attention is given to mobile projectors and their potential usage. However the question is asked if all this Mixed Reality technology is new to theatre. In the second half of the video examples are given of historic usage of Mixed Reality technology.

Chapter 12: Schildeurij (student project #4) and reflection by Marcel Alberts
PLMixedReality_deel2_06.avi (8:09 min)

The last student project group took the Droste effect, the endless repetition of an image in an image, as the starting point of their research. This ancient effect still has the power to mesmerize the audience. What will happen if somebody loseWeight Exercises their ball in a painting that is depicting the space where the painting hangs? Although the effect seems to be a simple live video feedback, suddenly the effect becomes much more complex, both technically and conceptually… Have a look at the Mixed Reality project page for more information on this piece.

In the second half of this video Marcel Alberts gives his reflection on the piece.

Chapter 13: Theatre outside the theatre (building)
PLMixedReality_deel2_07.avi (5:15 min)

Theater can both refer to the performance piece or the building in which this is performed. A theatre performance does’nt have to partake in a theatre building. This video is about using public space and the Internet as a theatre space. By integrating a non-theatre space into a theatrical context one could see similarities with Mixed Reality principles. A short moment is given to the Alternate Reality Gaming (ARG) as a potential interesting genre for theatre.

Chapter 14: This is not a conclusion
PLMixedReality_deel2_08.avi (5:30 min)

In this last video the Virtuality continuum model for mixed reality is re-introduced and compared with a model by Kaisu Koski showing a scale from the visible to the invisible stage.  Implications for the theatre making processes and disciplines are discussed. And finally a plea is made for investigating the potential of Mixed Reality technology in a theatrical context together without holding on to conservative ideas about what theatre is and how it is made (or tought in art academies).
