Final project idea - Affection

Taking care of plant is very difficult. If the person doesn 't take care of the plant, it will die because of the lack of water or sunshine. If the person takes too much care of the plant, such as giving too much water or over extended exposure to sunlight, it will die too. The plant needs proper level of affection to ensure vivid growth and ability to bloom. It is the same in the relationship between people or any life. There should be a certain distance to keep good relationship all the time.

This projects "Affection" is about the relationship between people and plants which also implies the right amount of affection for all relationship. If the user is far away from flowers, the lightings of the flowers will appear to be deem and will produce a dull sound. If the user gets close to the flowers, they will appear to be more bright, and will trigger a fast tempo music. However, if the user moves too much close the flower, it will blink the lights and will produce a high tempo sound; eventually the flowers will suddenly be turned off.

The light and sound are the metaphor of the plant 's life. So, the user will recognize the flowers becoming more alive, based on the brightness of the lights and speed and pitch of the sound. The physical distance will be used to define the affection level because the proper amount of attention is needed for a happy and healthy life. The project will be installed on top of the mirror with several flower shapes of fiber optic. It will be attached a distance sensor to detect the distance between the user and flowers.

Final project idea - center of the universe

When people look at stars on the sky, they are often impressed of how infinite night sky is. They begin to feel like they are the center in the universe. In eastern culture, there are some theories that the life forces of humans create movement in universe. So, if humans are the center point of the universe, then the universe can be moved by the free will of human.
This project will be creating an infinite night sky with lots of star to make people the center of the world, rather the center of the universe. This project will give people the feeling of importance of their identity. To create this universe, small lights, using LED or fiber optic, will be attached on mirrors inside of box. People ' s head will be placed in the box surrounded by hanging lightings

random idea - Secret Tree

When the people confess their secrets to the tree, the secrets make the tree grow, the flowers bloom and the fruits bear. In the book “The Giving Tree” by Shel Silverstein and the movie “In the Mood for Love” by director Wong Kar Wai, the main characters confess their secrets to a tree because it never tells their secrets to other people and it always keep them as long as the tree stays alive.
The project “Secret Tree” listens, interprets and stores people’s secrets in its leaves or fruits with a unique format. Afterwards, their secret is stored in the fruit and through a speaker other people will be able to listen to these secrets in a unique and altered format.

example and idea of FSM

Idea of Finite State Machine
Knob Puzzle The knob puzzle is consisted by basic diagrams such as square, triangle, circle, and star. When the piece of the puzzle is inserted in the right place, the user will get instant feedback from lights and sound. Also, the user will get finish feedback when he or she completes the puzzle.

Finite State Machine

A finite state machine (FSM) or finite state automaton (plural: automata) is a model of behavior composed of a finite number of states, transitions between those states, and actions. A state stores information about the past, i.e. it reflects the input changes from the system start to the present moment. reference : http://en.wikipedia.org/wiki/Finite_state_machine
