Wave Shield Update

Group Meetings Update
Sunday: LCC
The LCC students met up in order to complete the wave-shield and in order to begin working on piecing together the electronic/digital component of the structure. However, due to time constraints, we were unable to work past soldering the wave-shield together. Later, Daniel informed us that the wave shield was failing and that he was not sure why and that we would all meet tomorrow in order to try and figure out what was wrong.
We also brainstormed ideas for the sound interaction. We went through a few ideas including: Animal sounds, Space sounds, and Cartoon sounds though we could not decide which was the best because we were not sure how the structure would look and what type of interactions there definitely would be.
Monday: LCC & ID
At our set meeting time, we met and discussed slightly what it is that we needed to complete for class on Wednesday. The ID students decided to go pick up the boards and get the materials available in order to piece together our idea for the structure. The LCC students stuck around trying to figure out what could be wrong with the wave shield but decided that asking the TAs would be the best approach.
Tuesday: LCC & ID
A portion of the LCC students decided to work further on trying to get the wave shield to work. After further inspection, they decided that a few of the pieces were soldered on wrong and had to re-solder them. However, even after this discovery, the wave shield still did not work. The result of the wave shield is still undetermined at the moment.
The rest of the group met in the College of Architecture in order to become assembling the structure, using the templates that Paul sent out to the group. After the deserved structure was achieved, the placement of the sensors, speakers, and other components was decided.

Group Meeting March 8, 2010
Interactions:
Varying the tone based on the range finder
Wave files - play a melody whenever it senses something is in front of it
Faster or slower
Softer or louder
Varying note by the range
Varying the pitch by the range
If the emitter/detector pair is triggered then the range finder's ability changes
Sound ideas:
Digital sounds - 8 bit. This relates to the physical form because of blocky shape is reminiscent of Atari games like Jared mentioned in class.
Nature.
Ice.
We like the idea having soft, natural sounds that are not overpowering but also fit well together.
The users will know how to interact with the design just by approaching it and experimenting with moving through the space. This discovery is a part of the interactivity available to the design. The design of the structure itself affords the movement necessary for interaction. The use of the tunnel-like/cave-like structures affords movement through it and within it.

Group Meeting Update
Friday: At this meeting, we met to decide what work would be done over the weekend. Since we had to do some research in order for class next week, Daniel and Firaz decided to meet over the weekend to work with some of the technologies we discussed in class to help further our discussion for the next meeting. Yiran first notified us of the change in the structure of the overall design. Instead of having the smooth arch, a more angular arch will be used. Since the design is not finalized yet, it would be more difficult for the LCC students to know what the interaction is with the structure.
Monday: Before this meeting, Daniel and Firaz played with different sensors and lights with the arduino board, experimenting with that different technologies are capable of. In-O caught the LCC students further on the design of the structure and what parts of it had changed. The LCC students caught the ID students up on the technological decisions the class and groups have made.
Currently, the structure does not give much room for interaction. If the structure is too high, it cannot be used as a slide. Children cannot get onto the structure easily and also it would be easy to fall off and get injured. The structure really only allows for movement under the arch.
Daniel and Firaz found out that the IR Rangefinder work well in sunlight. The sun's rays did not affect the sensor in the way we discussed might happen in class. However, the testing did occur in the afternoon, on a relatively cool day and Atlanta can get extremely sunny and hot. Since these sensors will be under the slide, there is a lesser chance of interference from natural sources like sunlight, rain and snow. However, any sensors placed on top of the slides will have to consider these factors and be programmed to ignore their effects.
The speakers are each ~100mA. With the use of two speakers and two arduino boards, the total becomes 250mA. The circuit has two amplifiers also so the total goes up to 275mA.
After discussing with the TA's we learnt that powerful LED's consume 200-400mA of power. Any kind of interaction with lights will require many such powerful LED's which will in turn require a really powerful battery to power the entire circuit. As this would increase the cost of the units beyond the budget, it was decided to leave out the LED's from the design.
