Interaction Lab

A Knight’s Mission 

Many games nowadays engage with sophisticated design and user experience in visuals, sounds, and actions. We seek to develop a fun game focusing on this kind of interactive experience engaging mutual communications and jumping out of the boundaries of a stereotypical video game with controllers. 

We aim to create a game that requires a player’s action and movement, in hope of making it more entertaining and fun. We plan to design an adventure where players take on and overcome every obstacle one encounters. With support of sound and visual aids as well as physical interaction, we hope it enhances the level of engagement for players. By the end of this week, we need to finalize on the details, and start prototyping that tests the feasibility of the codes with the mechanism of the sensors.

From the beginning of the semester, we have learned that interaction is a “process in which two actors alternately listen, think and speak”, according to Chris Crawford. And at the research phase, the interactive project “Future You” really impressed me by its deep, back-and-forth communication with the users. It’s a reflection of the user’s movement and will evolve itself over time into a more complex shape. It speaks to what a good interaction is: it reacts to what a user does, the user receives it and reacts back on top of the conversation, and the content of the conversation grows. We wish to build something based on this kind experience, and make it a fun game. A successful outcome should be intuitive to play, so the audience from kids to the adult is included, and entertaining. It engages a rich experience of a user’s whole movement, making the game responsive to the user as if they are communicating in a real life setting. Since we have designs like VR that are aimed for visual pleasure, future steps can lead to how to make the game experience even more real and exciting.

Processing Etch-A-Sketch

The code of the drawing line is pretty much similar to the code of the button. It remembers the previous position of the line to draw a continuous line. Originally, when I turn the potentiometer to a really big value, the line disappears in the screen. So I need to map the value of the potentiometer to the corresponded range of the screen size.

Bouncing Ball

Making the ball bouncing was quite easy. But I spent some time working on the “draw()” function. I originally used the processing values to be the x-position of the ball. But it didn’t work. So I created a variable “x” and added an if statement to determine the time when to trigger the arduino.

Dodger VS Barriers

This kind of  dodging game mostly contain only one player competing with the system. We think it would be cool if this game is able to engage more players playing different roles. One player be as a dodger try to avoid all the barriers and another can create barriers as well as the size of them. Instead of being a stand-alone game with only one player, it’s a game that can be enojoyed with family and friends.

The Adventure in the Woods

We got an inspiration from this video. They use two ultrasonic sensors to locate the x-coordinate and y-coordinate of one object. We’d like to combine this with the game Minesweeper. And it’s also performed by more than one player, dedicating for a group game that is engaging for family and friends. Players have their respective piece. They move to different places in the box, and the computer tells them the number of the “monsters” near them, hinting the position of the “monsters”. The one find the treasure first alive wins. It’s a game requiring players to infer the possibilities, which is fun and challenging.

Dungeon Explorer

After the board game project in midterm, this project will be our further step to explore the board game world. We will give the user the right to choose 3 equipments for them to pack into their backpack before they enter the dungeon. After inputting which 3 equipments they have chosen, they need to use on of the equipments every time they met an “event”. Their choice will lead to different endings of the story.

Step 1

I created lightbulbs as my graphics. And repeated into a grid. At first I misunderstood the instructions. I made a shape instead of a function. 

And I also figured out that if I want to display the shape in random sizes and colors, I need to place those settings inside the for loop.

float x;
float y;

float size;
float r;
float g;
float b;
color c;

void setup() {
  background(50);
  size(1000, 1000);
  noLoop();
}

void draw() {
  for (int i=100; i<width; i+=100) {
    for (int j=50; j<height; j+=100) {

      size=random(50, 100);
      r = random(255, 255);
      g = random(230, 255);
      b= random(0, 255);
      c=color(r, g, b);
      lightbulb(i, j, size, c);
    }
  }
}

void lightbulb(float x, float y, float size, color c) {
  noStroke();
  fill(c);
  ellipse(x, y, size, size);

  triangle(x-size*0.4, y+size*0.3, x+size*0.4, y+size*0.3, x, y+size*1.02);
  rectMode(CENTER);
  fill(0);
  rect(x, y+size*0.9, size*0.4, size*0.1, 28);
  rect(x, y+size*0.8, size*0.4, size*0.1, 28);
  rect(x, y+size, size*0.4, size*0.1, 28);
}

Step 2

I made the graphics move around and bounce within the canvas borders. And I added a little interaction. If I press the mouse, the graphics gather at it. But I did face a problem. I didn’t know how to develop the movement from the original grid pattern, so I set them with random(x,y). If I have a more time, I may try how to let them move around the border of the canvas as well(like once they touch the right side of the wall, they move down along the border to the down side of the wall).

int count=100;
float x[]= new float[count];
float y[]= new float[count];

float size[]= new float[count];

float r[]= new float[count];
float g[]= new float[count];
float b[]= new float[count];
color c[]= new color[count];

float xspeed[]= new float[count];
float yspeed[]= new float[count];

void setup() {
  background(50);
  size(1000, 1000);

  for (int i=0; i<x.length; i++) {
    x[i] = random(100,width-100);
    y[i] = random(100,height-100);
    size[i] = random (50, 100);
    r[i] = random(255,255);
    g[i] = random(230,255);
    b[i] = random(0,255);
    c[i]= color(r[i], g[i], b[i]);

    xspeed[i]=random(2,10);
    yspeed[i] =random(2,10);
  }
}

void draw() {
  background(50);
  for(int i=0; i<x.length; i++){
    lightbulb(x[i], y[i], size[i], c[i]);
    if (mousePressed){
    
  x[i]+=(mouseX-x[i])*0.05;
  y[i]+=(mouseY-y[i])*0.05;
  }
  }
  move();
  bounce();
  

}
void move(){
  
  
  for(int i=0; i<x.length; i++){
    
  x[i]+=xspeed[i];
  y[i]+=yspeed[i];
  }
}
void bounce(){
  for(int i=0; i<x.length; i++){
  if(x[i]<=0+size[i]/2 || x[i]>= width-size[i]/2){
    xspeed[i]=-xspeed[i];
    
    
  }
  if(y[i]<=0+size[i]/2 || y[i]>= height-size[i]/2){
      yspeed[i]=-yspeed[i];
    
    
  }
  
  }
}

void mousePressed(){
  for(int i=0; i<x.length; i++){
  x[i]+=mouseX-x[i];
  y[i]+=mouseY-y[i];
}
}

void lightbulb(float x, float y, float size, color c) {
  noStroke();
  fill(c);
  ellipse(x, y, size, size);

  triangle(x-size*0.4, y+size*0.3, x+size*0.4, y+size*0.3, x, y+size*1.02);
  rectMode(CENTER);
  fill(0);
  rect(x, y+size*0.9, size*0.4, size*0.1, 28);
  rect(x, y+size*0.8, size*0.4, size*0.1, 28);
  rect(x, y+size, size*0.4, size*0.1, 28);
}

Question 1

I feel like it was Dynamic Passive at the first part because the size and color can change everytime I reopen the program. But it’s not really interact with me. And at the second part, it was Dynamic Interactive, since the shapes changed and moved by themselves, and I can engage in it activly.

Question 2

An array save us a lot of time and energy if we want create a massive amount of copy of something. We can use it when we want to make an animated poster with complicated patterns.

Research Project 1: Future You

This project impressed me when the first time I saw it online. I think it’s successful because not only it is highly interactive, but it creates a long term engagement with the users as the reflection evolves over time with more sophisticated and sensitive movements. And it’s also straightfoward in use. Users stand in front of it, see it moves in reflect of themselves, and thet know how it works.

Research Project 2: Liguid Midi

I think this is very innovative. They focus on the sense of listening combining with a user interface on textile. People can control sound and music when interacting with the piece of fabric. They explore a different possibility of using experience.

From the beginning of the semester, we have defined what interaction is. “Interaction is a cyclic process in which two actors alternately listen, think and speak”, according to Chris Crawford in his book “The Art of interactive design : a euphonious and illuminating guide to building successful software” (5). During an interaction, there should be a communication between at least two subjects.

As we made through our way to Group Project and Midterm Project, I realize that a successful interactive design is intuitive in using. When users first meet it, they can make sense of it little by little, like infant does, when interacting with it. Ernest Edmonds explained in his article that it is our intuition to “find patterns” to make sense of the environment. We are born with the ability and habit to ask ourselves “If I do this and that, will the world do some particular other thing?”, as Edmonds continues. Thus in a spontaneous interaction, there is no need for complicated instructions, and users can start engaging with the communication naturally. A very good example is the project above “Future You”. Participants can easily figure out if they move, the character on the screen moves too. And they figure out that it is their reflection.

Another thing I found inspiring in Edmonds’s article is the long-term engagement in interaction art. Instead of a short time reaction to attract users, the interactive experience evolves as time goes by. What we did in the class project focus more on the present feeling. A successful design like “Future You”, the movement and shape develop over time that prolongs the engagement of the participants, because they can see the change in complexity of the reflection when they stay for another few minutes.

For my animated poster, I made this words jumping randomly everywhere in different colors. And for homwork, I added some interaction elements. If I click on my mouse and move it, I can erase the words. If I feel it’s too tired to clean all of it–press DELETE and all the words on the screen disappear!

I had struggle on this: I added a delay to my “draw” because I wanted to slow down the speed of the popping words, but then the reaction time for my mouse and keyboard also got longer.

Seismic Zone

Jade Wen and Robbin Wu 

Instructor: Andy Garcia

In the previous Group Project, we did a device, which appeared as a pair of hands, that can create choreography according to their mood and lead people to dance once they touch it. It is a way for people to express their feelings in the form of art and we think it is interesting. Interaction plays an important role in this project because the communication between the robot and the user is constantly happening back and forth during the process. The robot reads the emotion, outputs the dance and the user receives the instructions. We use this concept of interaction in our midterm project. We created a board game, where players can build a building with blocks. Chances are that they may encounter earthquakes, which are simulated with the Arduino mechanism, that can destroy the building. Originally, we wanted to design something for professional urban planning. But a game is more interesting, and can engage a larger audience, from kids to adults. There are lots of table top designs and games that are intuitive for city-planning, but we want to add more on interactions with simulation of earthquakes and sounds. This kind of game is engaging within family and groups of friends, and also inspiring for children in the field of architecture, urban-planning, and engineering. 

We chose an ultrasonic sensor because since we intend to let users build a skyscraper in order to win the game, we need something to detect the height of it. We want it to be a board game that is fun and easy to understand for a wide range of audience from kids to adults. So we included cards that remain the typical feature of a board game. There are four kinds of cards and each represents a different action for that round: adding another brick, triggering a small earthquake, a big earthquake, and the ultimate earthquake. Unknown to what they will expect, it becomes exciting. And also we added another feature for a way to inform and celebrate a player’s victory. When they hear the music from the buzzer, they know they have succeeded, and meanwhile, dance to it! The audio is better and more engaging than visuals such as a lightning LED.

During the code part, Robbin took charge of a big portion of it. The most difficult part that took lots of time was testing the range of the motor rotation. But all we needed to do was test it over and over again. The distance for the ultrasensor was in a similar situation as well, especially when we built the model separately, we had different numbers in the code and needed to test it several times. But Robbin was very helpful and approachable even though we could only contact each other online. In addition, when I built the model, I figured out the ultrasonic sensor was a big problem if I attached it in the cardboard box. First I made a hole on the top of the box that the sensor could fit in. But when I tested it, the buzzer made sounds even though the distance was further than the designated number in the code. I guessed it was because the ultrasound it sent bounced back when it hit the sidewall of the box, which led to the miscalculation. So I cut the box and made it a more open area so that the side of the box wouldn’t affect the soundwave.

Another adjustment was made to keep the platform stable. Because we use a servo motor to simulate the earthquake and place it under the surface where players build their skyscrapers, the surface tended to move around when it was vibrated by the motor. So I needed to add some blocks to prevent the platform from moving around. 

In conclusion, we aimed to create a simple but interesting board game for people from all ages that is inspiring for urban-planning and house building. In terms of interaction, it fits my understanding resulting from the last group project. The earthquake is triggered by the reading of the buttons and the motor takes actions that knocks down the building. Even though it reacts to the building but not directly to the player, there is conversation, input and output during the process. In the game, players build up the bricks with chances to encounter an earthquake if they flip a card that instructs them to push a button to trigger an earthquake. They aim to get to the fourth floor as fast as possible. It can be very entertaining thanks to the unknown situation in the next round, and as well be inspiring and challenging since they need to balance the time between building a steady tower or moving into the next round. If we had more time, we can upgrade the bricks into, instead of only cubes, but different shapes. So it requires more strategies to the game and is more challenging in an urban-planning and architecture aspect, which fits even more to the goal of our project. That is, it is not only an entertaining game, but a learning experience for children and family to build up collaboration and city planning ability. 

This project was the first one I did that integrated prototyping models and coding. Different to what we did in the previous Group Project, there were more technical issues that we encountered outside of our expectation. Feasibility is something that we need to take into consideration during the planning process, and research as well. Also, it takes time to build and create something. We need patience to ideate and test it again and again to reach our expectations. And with some creativity, everything can be fun and meaningful.
