BIG project for Chang Theater

For our project that we do for Chang Theater. We create clothes with LED light and pole with LED, I will give the detail for this project.

In 9/05/2557 is the first day that we're come to meeting and our senior let us to do the work. We divide into 2 group : programming and hardware.Before we working our senior talk with P'Bo the designer about clothing style. I choose programming and in first day, we can program on auduino a little bit for test led can work.But here is an overview of duties. In other day, we have divided into several duties and I am  responsible for wiring of clothing.

For programming with Auduino the job that we have to do consist of :
1. Make it can on/off every Led through Wireless and have simply interface for using. In the beginning we try to use Xbee. We try to connect xbee with computer and check it, it's not work because we doesn't use xbee long time and it's very complicate. So we change into NF24 instead Xbee because it's more simply and cheaper.

This picture we before we use NFR, we try to use Xbee first but it's not work.

2. Control LED strip that we install on pole. In this show, when actor touch the pole the light will turn on and move around the pole. Luminescence of the LED is depend on how strong touch with the pole. In this we use Piezo Vibration sensor is used to aid in the vibration force.

3. Turn on/off LED via button. We put the button with the costume, it make our job more convineince.

4. Make all Led lighting by the volume of the music. In this part we use microphone for receive sound if music is lound so the led will have more light.

This is overview of our project, I will give in the detail later!!

Today Kru'Pichet Klunchun tell us about meaning of LED light. He teach us that the role of artist is make light have the meaning and give imagination to all the people. Like when you watch on the stage, when the light is turn on or off all of this has the meaning for audience. Technology in theatre all the light is complex in audience's feeling. The light acts resulting one-dimentional, like we use one light to focus on the only one actor that is we can see the meaning of light. If we want to show performance that without actor, we can use only the light is also can tell the story too ,and the light can make audience to have feeling or emotion with the show. Light can be made to feel our fear, excited, sadness, funny and etc.
Another job that important is lighting designer. It is meaningful process then use light to act define it. Lighting designer will use the correct lighting to convey meaning.
In this work, three people are working together:
1.director
2.lighting designer
3.music director
They have the power to decide as well. In Thailand we don't have lighting designer. This has a lot of impact, the spirit of the people in a society hardened, social problem. Kru'Pichet told us he use lighting designer of Japan. On the state he told us, they have a problem in performance dance :
1. Energy - audience can't see that dancer have energy.
2. Can't feel all muscles of the dancer while working.
3. How to make audience to feel tired and breath of dancers.

----------------

In this show thay devide into 3 part that Kru'Pichet need us to develop for them

1. Shirt 

    The idea of this shirt : 1.) transparent shirt - it about sexual, to know the real of people

                                    2.) light - to show military , to show a powerp

    Meaning - 1.) we can convey the emotions and feelings of the person through the light without movement or minimal.

                    2.) Emotion or feeling of human, we have our limits. Hence the need for technical help convey the mood is intense.

2. Pole 

    The idea : How do we convey the pain. When hit the pole and people can't hear the sound so it can make audience can't understand what actor want to say.

     Meaning - Talking about sexual men because in art can not communicate directly.

3. Water bag

    The idea : they want to build another world. For people to escape from the world of reality into another world.

So the next job that we will do is develop the bodysuilt with have led light, develop the pole with led light and etc. I will show the work in next time SEE YOU!!

Week 11

So let's start with what is Physical computing. It is can be any device that you can touch such as ubiquitous computing (as embeded computing, etc.) ,iRobot and smart things. And I will give you an example that you can understand. We learn about Standalone object.
Standalone object is create one object that it can stand alone.(At first I try to search on google.com to find meaning of this word but it relate to programming so I use meaning that teacher tell me in class).
Example of Standalone object

A Stand-Alone Smart Watch 

When I first spotted the Omate TrueSmart - a smart watch that doesn’t need to connect to a smartphone—I was, to put it politely, skeptical. With its own wireless data capabilities, a fully functional Android operating system, 1.5-inch touch screen, GPS, and dual-core processor, the device is basically a tiny smartphone with a wrist strap. I figured it would be overloaded and unusable, as well as overly expensive, since it requires its own data plan to take advantage of all its functions.

Smart hug 

Beginning physical computing that use Lilypad to create.

So the next example of stand alone object, we talk about Micro-controller 

In past our department we used basic stamp for learning that very old before have Auduino pop168  does not require a lot of units processing so it can be stand alone object.

In the beginning, Auduino is popular with Artist not Engineer.

Phidget is physical computing + budget.

Artist design simple interface, big function and easy to program. Artist thing on activity base, function   of works are under on those activity but engineer thing on function base, focus on function.

And next topic, communication between physical & virtual.

Humans are intermediate between computer and output.

Transduction is exchange of energy from one side to computer.

       Input -------------------> Output

From Input is guys sensing to physical stuff than transfer to electric signal. Example ; press the button for produce output.

Service Design

Today we have watch video in topic of Service Design. It has 4 part.
Let's see the first part is about "What is Service Design?"

In the beginning of video, they compare about 2 cafe' that have the same price, same flavor and located close.
So how do we decided ,what cafe' do we like? it's depend on service design and principles of Marketing its 
called '7Ps' that contain : 1. People is relationships with customers and provider.
2. Process is design process for customer convenience
3. Physical evidence is Design service points that for convenience of customers.
That is the point that service design will come for help by bring way of thinking and practice of design for 
develop a service job, by classify into 3 part :
1. Exploration is research and analysis in order to understand the real issues.
2. Creation is the results will be used in the design concept.
3. Implementation is experiment and adapt the concept actually works.
That three step is a continuous process that must be repeated over and over. Service design will be the
 fundamental to the business in the long run.

Introduction to service design to be efficient, first step to do is exploration, this allowed us to see an overview
of the business (stakeholder maps). Let me summery for you, efficient data collection will allow us never get lost. 
And to design services that respond to the real needs.

After we have found the real problem of exploration stage then the next step of service design is creation or
 adoption that problem to be question of design concepts.
When step into a creation methods is to design scenarios for simulate different parts of the service. 
This associated with customer journey is another important tool for a service design that help us overview 
of the entire project step by step. Design guidelines that are caused due to the perfect combination of reasoning
and creativity. This will allow us to design services that meet every step as a before, during and after the service. 
And create great value to the business.

The last method of service design is implementation or bringing the idea of ​​the creation of phase to test for
errors, and updates can be be practical. One way is to create a model to test the concept in actual work. 
To check on run real application of that both the customer and providers will interact to do 
with that concept. Addition configured, questionnaire should be prepared to be a help in evaluating the test 
that the idea is good or not good enough. And when we have a complete design service and ready to use.
The service blueprint is an important tool in communication. For everyone to understand each phase of the
system. The work of all points in the business is relevant and consistent with the concept that we create a 
new one.

Our project LED

Our group AM'PM doing project about Interactive LED table.

Beginning with equipment that we need : Arduino , LED (White), Resistor ,LDR (Light sensor) is the most important. So we start with the smallest circuit by we search on internet how to make LED turn on when have low light then we do as a prototype as you see in below picture.

We try to make a simple circuit first than we build a real prototype circuit.

We use Auduino and basic code to make led light and down when hand pass.

And before we can do this circuit, we do circuit board by ourself. We use dryfilm to do. Let follow the link that our group search for doing this circuit : http://www.thaimicrotron.com/Trick/PCB/Dryfilm.htm

While we working the first circuit board its not work so we redo it again, in second time we not miss it.

This is the basic circuit that I research for using arduino with LDR

And this is a code that at first we use with our prototype at its work!

Code for LDR

int ldr = 0;             //analog pin to which LDR is connected

int ldr_value = 0;        //variable to store LDR values

void setup()

{

  Serial.begin(9600);   //start te serial monitor

}

void loop()

{

  ldr_value = analogRead(ldr);          //reads the LDR values

  Serial.println(ldr_value);                 //prints the LDR values to serial monitor

  delay(50);                  //wait

}

Then we got this!!

 

week 10

Let's continue on Usability Engineering !

Usability Metrics is how to measure the quality of a product, it should be efficient, effective and satisfying.

Efficient is once users have learned the design, how quickly can they perform tasks?

Effectiveness is the degree to which something is successful in producing a desired result; success.

Satisfaction - how pleasant is it to use the design?

Learnability - easy to learn easy to play.

Errors is the key point, when user want to perform action but output is not as expected, its due to misunderstanding of system. A few error is made work successful.

Time is another class can measure of efficiency like how long it takes to perform the task.

I have to research more on the advantages and disadvantages of Usability engineering.

Benefits of Usability

User Effectiveness

     Increase success rate and reduce users errors

     Improve ease of use and ease of learning

     Increase user productivity and user satisfaction

     Increase user trust in the system

     Reduce support costs and training costs

Development Costs

    Reduce development costs and time

    Reduce maintenance costs

Revenue

   Increase product sales, revenue and market share

   Increase site traffic and transactions/purchases

   Attract and retain more customers

 Lack of Usability

Although the definition of usability may be the subject of some discussion, lack of usability is readily recognizable. Systems that lack usability are characterized by:

    1.Existence of workarounds - because the interface is difficult or does not match workflow in the real world, users develop workarounds to compensate for the inadequacies of the system

    2.Low usage levels - Users use the system as little as possible. 

    3.Dissatisfaction - Users, and particularly novices, will find the system difficult or frustrating to use     4.Rework or double-handling - Inefficient design often means that the same data may need to be entered or read more often than is necessary. 

Because incorporating usability is a quality activity, it often occurs that systems with poor usability are also deficient in other areas. For example, they are likely to be crash-prone, poorly documented and difficult to maintain.

Thanks for today! 

week 9

At starting, we talk about คุณ พิชิต. He is storekeeper. TCDC has built 10 years ago and organized exhibitions for 2 times. And he talked about process of exhibition.

This is picture that teacher explain us about process how to design exhibition.

So we should have wider prospective then we should research the information for expand all knowledge. And then we scope down to get main point. Next step we create content strategies or story line.

Plot of story telling - it create emotion, like museum have it too. It has a turning point that peak emotional of audience. 

Teacher tell me in class room, every movie have turning point like if you watch American's series or Korea's series at the end of chapter, you felt like you don't want that movie end that is turning point in museum has it too.

Today I have learn about Usability Engineering.
I think concept of Usability Engineering is try to make product easy to use and ergonomic. Developer should understand user, task and environment.For understand user is the first job that you should do and classify level of user (Novice, intermediate or expert).Then you gathering information about users, you can do it has several method for you (Interview, Questionnaire, etc). In Japan designed refrigerator can opened both left and right size for who left-handed that is designer understand user. For task analysis, task is to be sure about the job you have to do for achieve a goal.
A task consist of :

is a process that convert the input to output, like game 2048.

Ethnography is observer not separate from user which is stay together for observe.

Continuous on next week.
