Research Agenda and Process Overview waves pulse is a interactive design project that uses human movement to produce ripples. The main idea is how the concept of light, movement of waves and shadows in a ripple tank design to produce a sensory experience within the space including space and human movement in the atmosphere. This study looks towards the atmosphere and provision of information relating to water wave shadows.
Research Questions 1.
water waves shadow is outlined to show how effective atmosphere can be created in architecture through invisible media?
2. how architecture can influence the the atmosphere of the spacethrough movements of water waves shadow? 3. How people are moving, act in the space and create atmosphere for the space. 4. How to controls movement of water waves by designing a vibration device?

Research Statement
Significance and Contribution The sensation of the atmosphere is vital as it helps individuals to translate their movements into a medium of light and waves. The project developed through prototyping stages for vibration devices , using different speed motors and fabrications design process.
Methodologies 1.
Vibration device system is based on the multiple components. A 3d design for the device was developed that could simulate possible design techniques. The final design of the vibration device was achieved by examining different motors speed, box design and choosing the one that consistently produced stable and control formations.
2. Material testing, prototypes and product development through using of bending materials and plastic. 3. Digital computational operational control and simulation of machinery using 3D printer.

Design Proposal This design will feature a ripple tank, suspension in the ceiling allow adequate space for projection. There are two waves medium to play in this design, the use of water shadow and light. A light source will be placed within the tank and aimed at the water, then reflected onto the floor and walls to show the waves shadow pattern .The ripples will be caused by a small mechanical vibration devices that would produce water waves shadow. These vibrators will then be connected to an infrared motion sensor that is attached to the outside of the tank and facing
downward. As viewers walk by the tank, their motions will be detected by sensor and cause the tank to create ripples, which will be reflected on the walls and floor. The wave patterns depicted by the light should vary in accordance with the speed and direction of the participant’s movements.
Key technological outcomes of proposal 1.
Generating morphologies for making vibration devices that produccontroled waves patterns
2. Ways of addressing the technical structure for the project 3. Having a controled systems for the whole project by connecting it with sensors to translate movements of people into the waves patterns.

Design Research Context Field of Work
Work by others
The project is situated within a dark room context becasue it will emphasis in creating the atmospheric of the waves patterns.
Doing the mechanical process using the 3D machine operation to produce 3D CAMs and motor boxes from 3D printer.
1. Theory: Theories of desingn made through mechanical production of the vibration devices. 2. Design: focus on vibration device and materials for the dipping arms whcih is necessity for creating the effect and to be more efficiently.

Design Methodologies The wave pulse project has two ripple arms controlled by motor movements to creates vibration in water surface. Through CAMS design that holds the ripples arms creating differen waves patterns. The shape of individual Cams are designed to produce specific types of motion. When the cams rotate, the ftat followers respond to motion according to the profile of each cam. Each box has different types of CAMS design . The first CAM is a simple spiral. As the cam turns, the flat followers rises at a steady rate until it reaches the step where it drops suddenly. [fig.04c ]
The second CAM has more harmonic action in creating the ripples pattern as it is rises and falls with contiouse drops. [fig.04c ] The third CAM will produces several short up and down movements from one revolution which creates several events with smoother motion. [fig.04c]
Critical Design Elements 1.
Design a vibration device.
2. Desing rotaring CAMs profile for the Output Motion . 3. Design timber Boxes with reasonable lifting weight for one person with suitable set of suspension clips will be used to hang the boxes from four connection hooks per box.

Process & Methods
Prototyping and testing In order to develop a vibration device that could be truly engaging to produce effective ripples pattern in the floor , cutting flexible pending timber , using different motors speeds prototypes were produced and made available to test. then 3d printing dsign for a box to hold the motors, timber pieces and the led in a propoper position to gets the perfect ripples pattern . The construction time box size that would hold motors and Led size is a formation of 55cm Ă— 45cm Ă— 10cm. [fig.04]
designs techniques that could holds the motors and dipping arms to creates the perfect ripples and dipping. b. Box manufacturing motor box was design using Rhino and sketchup then processing for a 3d prinnting for six boxes c. Vibration device design The vibration device was based in desiging a CAMs that gives different language for each box. d. Overall form models

Process & Methods
Fabrication Techniques The wood box structure is made a.LED Material and shape of timber that suitable to hold two LED are design to be integrated vibrations boxes in each sides. in the vibration box in a way The vibration boxes are made that it should be at top of the using 3d modeling and process the dipping arms. The two arms of 3d printing. Each box has 3d holding the LED are made of printing CAM, cuttig of flexible metals which is a hand made timber pieces and two metals bending by pressure on surface sticks attached to smalls balls of dome shape. Each of this arms whcich helps to create water holding hidding wires inside the waves vibration. curve for the wires connections. six LEDs are connected using a LED circuit diagram. b. CAM manufacturing CAM are design to gives different displacement by changing the the angles to get differnt rise and falls. c. Dipping arm manufacturing Dipping arms are made of metals sticks which is manufacture by a process of hand made cutting for the desire length. d. Hanging technique The structure of the three suspensions boxes are designed to be a reasonable lifting weight. Suspension techiniques with a set of suspension clips that will be used to hang the boxes from four connection hooks per box.

Occupation and Interaction A success use of Arduino software and hardware which will senses the environment by receiving inputs from many sensors and affect it is surroundings by controling lights and motors which will make a controlled ripples pattern in the space which will give a sensory experience with a movement in the space translating the ephamare quality of water to controlled space. water pulse is translating the movement of people into the medium of light and waves by
detecting people movement into the space which make people who will be the one creating the ripples effects. By doing this , it will be influencing the atomospher of the space by non physical experience.

The processing of that information and the development of the decision to have waves patternthat makes induvials to change direction of movement and action. The cause of such movement can be said to be the sensation of ight waves patterns.
