Journey of Light and Shadow. How to use architectural concepts of space to understand personal interaction with the environment?

Introduction This project is about a peculiar journey in which the crucial aim is not necessarily to arrive the final destination but to record and describe the experiences of journey by the observer. In other words, the most relevant aspect of this journey is the information being “experienced” by observer before reaching the arrival per se, in Stone Circle, a historical site located in Oxfordshire(UK).

Initially, the project investigated a series of narratives that reflect interactions between the observer and environment. These narratives are constructed by photographs taken along the journey. The journey to be presented will be divided into four stages. The first one is about preparation for the journey. Secondly, the transport during the journey is shown. In the third stage, the experience of “touching” the environment will be emphasized. Finally, it will describe the perception of arriving.

The first stage of this project is a gradual process of collecting fragments of narratives available through the track. The purpose is to use the concept of ”light and shadow” to discuss not only how they are entangled with the environment but also to what extent they establish an original “conversation” with the architecture. Hence, this project focuses on the light and shadow as elements appropriated by architecture.

In the second stage of this work, the goal is to explain and describe details of the photographs taken in the previous stage. These pictures represent the experience about the journey and will be analysed according to their perspectives of light and shadow.

At the same time, the project analyses and interprets the effect of light and shadow through a succession of drawings. In the context, the drawings are results of experiments made to test a subjective or even abstract conception about how light and shadow can be projected in the environment. The pictures are frozen images of the journey; by contrast, the drawings are a result of dynamic experiments. The drawings should be understood in this project as the bridge between environment and architecture.

By using distinct means of representation, such as photographs and drawings, this project suggests that there are multiple ways in which observers can establish an interaction with the environment.

Consequently, different connections between the environment and the architecture can be possible.

In summary, the project develops a series of drawings about an original journey of light and shadow; in which surface challenge the concept and the perception of the traditional model of space in depth. This project proposes an initial work for developing 3D model to depict the spatial journey.

Motivation The main interest of this work is the interaction between people and environment, and how people perceive the world where they live. People can smell, see, touch, and listen, when they live in certain environment. The interesting issues are: what other forms of interaction with the environment would remain? What kind of conversation would exist between observers and objects?

Fascination for the relationship between light and shadow is the key aspect of this project. It also attempts to discuss how light project the shadow of an object to the surface, and how shadow can present an image directly. In ‘The Republic’ Plato states that “the shadow is even further away from the truth than the mirror” (Hill, J. 2006). This shows how the representation of shadow has been a fascination of mankind since antiquity.

Light and shadow exist simultaneously. The shadow is shown as the silhouette of an object from the ray of the light point’s perspective. On the one hand, the shadow is the trace of light that projected in the environment. On the other hand, it is the object itself that “touch” the environment through the light.

Then the shadow is generated on the surface as an image of object.

This project was constructed by using the touch as a method to explore the natural world. Touch can be defined as the ability to do things “in the stated, especially positive way” (Cambridge dictionary). It is also a bridge which permits the communication between the natural world and the architecture. The sense of touch obviously plays a unique and important role in human interactions.

Touch can also have the dimension of a sensory mode that integrates our own experiences with our memories. When visual perceptions are connected and integrated into the habit continuum of individuals; my body remembers who I am and where I am located in the world. My body is truly the central point of my world, not only in the view point of the central perspective, but also the very locus of reference, memory, imagination and integration.

This research is also an attempt to use technology to translate the observer’s experiences through the journey. When technologies facilitate communication, they are in a way amplifying our natural senses and perception. For instance, using ultrasound technology scan can show what is happening inside of human body. It can reveal the organs beneath our skin. Digital technologies give us the opportunity to be aware of the existence of different spaces, and the possible communication both inside and outside of ourselves, close to or far away from us.

Methodology This project will apply the method of "touching� to address the relationship between the observer and the environment. The touch is presented by the forms of drawings, photos, and experiments that utilize modern technology devices. These methods focus on analyzing light and shadow. They try to record the journey of the observer by integrating the different forms of presentation. A complete investigation flow will be described at the end of this section.

The photographs are taken by specific angle and position to capture the movement and the reflection of light and shadow in the environment during the journey.

Portion of drawings are constructed by the experience of journey in order to support the narrative of a prior departure. Some drawings are drawn by analysing the detail of photographs. The rest part of drawings is produced based on the experiments that develop the object to investigate the relationship between light and shadow.

The experiments are implemented by investigating how light and shadow project the perspective to the environment by using modern technology device.

One experiment is by using GPS device to track the route of journey for the purpose of recording the moving path. Another one is by using the tool equipped with light sensor to move around in the darkness space. The movement of tool will leave trace on the surface by reacting with light. According to those experiments, the project develops the sensor paper which has reaction with light, in other words, it develops the observing drawing.

These works about the project are also presented on my personal blog (http://mei-space.blogspot. com/). The personal blog is to guide and upload this research, and further to clarify concepts used in this project. This research focus on the interaction between light and shadow, It presents how the observer communicates with environment is by the experience of the journey. .

Supported by these experiments, it is reasonable to argue that representation of the physical architecture operates differently on the mind of the observer by using touch. The method of touch is visible through drawings; additionally, photos also capture the shadow of objects which have left the trace to the surface during the journey.

Definition In this project the word “touch” will combine multiple meanings as mention below.

“Touch” is the bridge to negotiate the gap between the observers and environment.

1. Touch, noun -move hand: the ability to know what something is like by feeling it with the fingers.

2. Touch, verb -move hand: to move especially the hand or another part of the body lightly onto and off something or someone 3. Touch, noun –close together: to communicate or continue to communicate with someone by using a telephone or writing to them.

4. Touch, noun –ability: an ability to do things in the stated, especially positive way.

(Cambridge dictionary) The gap implies a new kind of space. It is the space in-between that defines the potential depth. The space of the interval is a shallow and compressed space; it is unfolding in time and linked together by the perception and recall of the observer.

The reflection 1. Drawing

The investigation work :experiments and the drawings

“In architecture projection space is nothing other than pictures of light”. (Panofsky, E.,1968 cited in Evans, R., 1995, p.108).

B-1.The reflection As a whole, forms of life and the environment depend on sunlight to create and maintain ecosystems. Light is not only closely intertwined with our bodily and perceptual sensations and situations in daily life, but also a fundamental substance that makes a diverse range of objects visible, things and situations. For human beings, light is not only a matter of existence and survival, but also a spiritual and mental guide, assigned religious, scientific and philosophical significance of them. For artists, light path implies the line of drawing; it also reveals things in order for drawing about them to be produced.

Light is the ultimate geometric instrument; this fact has been proven by contemporary laser surveys. In Euclid’s ‘Elements’, the straight line is defined as what can only be interpreted as a line that looks like a point when seen from end on, in other words a line that is identical to a light path (Sir Thomas L. Heath, 1968 cited in Evans, R., 1995).

During the journey, the reflection of light reveals the environment’s image. The drawings present the physical architecture where the observer has visited. The drawings are constructed by experience of journey which is “touching” the environment. In addition, the perspectives are drawn from the position we occupy as we observe the space. The camera angles are also taken from the perspective of the observer experiencing the environment. Here are the drawings that describe third part of the journey.

The reflection 2. Experiment One of the fascinating projects based on modern light art is “Light Space Modulator” which was designed by László Moholy-Nagy, 1928-30 (Popper, F., 2007). The power of this work depends more on the reflection than on the original material.

This experiment uses the reflection of light to capture the movement of shadow. The project develops one object that is operated by hand. The object can change the angle to measure the space of crevice where the light is hard to reach. It is interesting when taking the object into the experiment and surveying its environment. This work assists my project in experience the reflection of light. It investigates the shadow by observing the trace of light. The work records the movement of the object to trace the route of shadow during the environment. It is the experiment about light and shadow. The perspective of shadow can be drawn through the object.

The drawing presents the trace of light as well as the movement of shadow in the environment through out the experiment.

The photos of the object show experiments and measurements upon the space of the crevice within an environment.

The trace 1. Drawing

The investigation work :experiments and the drawings B-2.The trace

The shadow is the geometric shape of the object. It is shown elementarily as the silhouette of an object from the ray of the light point’s perspective. In other words, the shadow is the trace of light that has been projected upon the environment.

In this stage, the project investigates the space that exists after the drawing.

“It is important to remember that in the classical tradition, drawing began when a Corintian maiden outlined the shadow (a profile) of her departing lover on a wall.” (Pérez-Gómez, A. & Pelletier, L. 1997, p.112) Many discussions of drawings begin with the classical legend of the origin of drawing.

The trace of a shadow’s outline is sometimes cited as the first drawing or painting. In other words, drawing is the trace of shadow. Meanwhile, a drawing is like a window through which we can see things and environment (Booker, P.J., 1963) From ‘Projective Cast’, Robin Evans (1995) which states briefly that: “architects do not make buildings, and they make drawing for buildings.”

They not only design the object but also draw the environment.

Without drawings, there would be no environment (Evans. R.,1997). Drawings depends upon how observer sees, interprets and analyzes the environment. At the final stage of this journey, the Stone Circle is the point of departure. It is the space wher the heavenly sphere is transformed by the shadow’s projection. The trace of shadow is presented the space through the drawing.

The trace 2. Experiment The experiment is to investigate the space exist after drawing. The project uses one tool that is equipped with a light sensor to move around in a darkened space. The movement of this tool will leave trace on the surface by reacting with light. In the end, the drawing of trace is represented the dimension of the space.

The image shows the movement of the tool. The video uploads in the personal blog.

This project also researches one of the works of Jochem Hendricks : “Eye-drawings”, which was made in 1992-93. Which also uses the device to record movement. The fascination of this work is the drawing of trace. It uses interactions from the human eye to trace the movement. The drawings are done directly by the eyes without using any hands.

The experiment of investigating the space exists after drawing and the research of Eye-drawing, the environment is tested out by the project. It takes the paper as the physical architecture which is used to observe how light projects objects and how shadow leaves trace on the papers. The work inspires the project to develop the sensor paper which has reaction with light. The sensor paper is folded and cut by the reaction with light, in other words, the paper exists in the shadow space. In the end, the fragments of papers are collected to represent the space where they have been surveyed and measured. It is the dynamic drawing; more specifically, it is the observing drawing of drawing.

The trace of a shadow’s outline truly reflects the reality in the environment.

In this journey, a GPS device is used to record movement on a given path for collecting more elements throughout the journey, photos are taken at the same time. The purpose of using a GPS device is to navigate with the use of satellite technology. The observer relies on this technique to arrive to the point of arrival; meanwhile, the path of the journey is also recorded.

After returning from this journey, the information can be collected and uploaded to the website.

The personal experience of the journey becomes a saved file in the internet. It is a form of personal cartography that documents an occurrence in life as a visual journal. The picture in next page is an image captured from the website. Information about this journey is also linked to my personal blog.

At the point of arrival, these technological devices can not only record the path of the journey, but also define the position and direction of sunlight, this information is also collected. The project depends on this technology to analyze the trace of light during a particular period of time in Stone Circle. This work also helps reveal the movement of shadow in space.

The movement 2. Drawing During the journey’s trajectory, the photos also capture the movement of light and shadow within a particular environment. For instance, in Part three, 3-1, 3-2, 3-3, 3-5, observe the detail of the A GPS device is used to record movement

interaction between light and shadow. The photos fix the movement to one period of time and the drawings reveal the dynamic interaction in the environment. The drawings represent the image of light and shadow that shift and skim on the surface.

C. Summary To sum up, this project had implemented several experiments and produced many drawings which use different methods to describe the environment by investigating the relationship between light and shadow. Because of these works, it assists to reveal the implicit conversation and to reveal an interaction between the observer and the environment.

In comparison to the other projects researched, this project presents the drawings by using technology to communicate. It uses some modern technologies to amplify human’s natural senses and perception to aware the environment.

The purpose of this project is to examine and represent the relationship and the interaction between the observer and the environment more precisely, in order to bridge the gap between them. The gap is the space in-between and unfolding in time. They are also linked together with architecture by the perception of observer.

In the end, the project proposes an initial work for developing 3D model to depict the spatial journey.
