Island Hopping

The basic idea of Island Hopping was to use what we’ve learnt through the two assignments and come up with various physically executable ideas. It was important to focus on actions in the real world. Use these actions to find out ways of interaction. Different ideas put forth were walking, jumping. We were supposed to develop a method to promote interaction. Our team did not use the PCB circuit but instead hardwired the whole game. We thought of various interactions without constraining ourselves to using computers. We focussed more on interactions and user-experience.

Final concept: Real World Scenario
A person has to cross a river\lake and reach the other end. One stone is visible in the river when person stands on it he\she is able to see two more stones in the river now person has to select the correct stone to find next to stones and proceed ahead. If person steps on the wrong stone then he\she does not get the next clue and fells in the river.

Conceptual Prototype
We thought of using colourful marbles in place of stones and use the LED lights to imitate appear disappear action of the two clues. In this prototype game person has to press a start marble. When start marble is pressed other two marbles gets lit up (LED below marble lights) and same process continues if the person goes on pressing the correct marbles. If wrong marble is selected then no further clue is given.

Hardware: Tools
LED’s(15), Resistor(100 Ohm), Battery(6.3V), Switches, Toggle switch (main switch), Wires, soldering iron, soldering wire.

Diagrammatic representation:

Prototyping:
When user presses the marble the switch below marble gets pressed, the circuit gets completed and two LED’s (below the marbles) in the circuit gets lit up which act next two clues to proceed in the game. Among the two marbles one has switch below it which is considered as a correct option since next two LED’s lit up after pressing the switch and other one doesn’t have switch below it. Such seven steps are present in the game.

Process:
First we thought of giving a input to computer and then let computer give back the output which LED’s are supposed to be switched on. Then we thought of getting rid of the computer and writing our own logic.

In real life scene it is a path which person has to travel so the next clue stones have to be placed near to the stone person is standing but since it was a game board we thought of selecting marbles at random(anywhere on the game board).
First we tested all the components and implemented the circuit on the board. Then we soldered and fixed all the joints and made sure that all wires and all components are at proper distance and not causing short circuit anywhere.
Then we made a compact box so as after placing the board inside it the circuit is not seen from out side but still remains accessible. Even battery was placed inside the box. Everything became one product.

Feedback and Inputs:
What is good?
• It is fun to play
• Interaction which does not involves computer or any other digital device.
• Self generated logic.
What is bad?
• There is no negative feedback.
• Fixed logic; so becomes predictable after some rounds of play.
• Can add more complexity.

Conclusion and Extensions:
Create various levels
Introduce complexity
Use the computer to generate different route every time.
Use more sophisticated hardware. We can use just metal touch switches to increase the sensitivity.
