Novel Interaction Technology – Coursework 1

Objectives

* Age range 4-7
* Educate them how to match animals with their names in fun and enjoyment environment.

Introduction

Text

Methodology

Our flow chart starts with a welcoming screen. Next and by using fiducial symbols, user will be able to move on to the next screen. This screen will show a picture of an animal and asks you to find out the name of this animal. If you get it right, you will have the chance to move on to the next screen where another animal picture is shown. At the end you will be thanked for your participation.

Below is the flow chart of the main ways where the user takes actions to move between them:

Start

Show fiducial symbol

If fiducial symbol = 1

Show animal image

If fiducial symbol is matching

Try again

No
Show fiducial symbols 2-6

Yes

Scores = 1
Show animal name

Do you want to continue?

Yes

No

End

Target group

* Children
* Age range 4-7

Design and usability considerations

* Game
* Tangible User Interface
* Educational
* Fun and engaging

Designing the prototype

For this project to be done, we needed computer or laptop, webcam, Processing and Reactivision programs and fiducial symbols.

Below are screen shots of our game:

Screen 1 – This is the introduction screen that will be displayed once the game is run.

Screen 2 – If you start the game by showing the fudicial symbol 1 to the camera, a screen with a cat image will be displayed asking you to match the animal name to the displayed image.

Screen 3 – If you get the right answer by showing the fudicial symbol 2 to the camera, a screen with a cat image, the correct answer (in this case the word ‘CAT’) and a (Well Done !) message will be displayed.

How the game will be played

The game is based on tangible user interface. It is educational, fun and engaging and the interaction in this game is pretty simple and straightforward.

The game starts with a welcoming screen. Using fiducial symbols, user will be able to interact and navigate through the system. To start the game, the user has to use the correct object where each physical object corresponds to a possible answer. In order for the player to give an answer, he has to shows to the camera an object tagged with the appropriate symbol.

Now the first screen will show a picture of an animal and asks you to find out the name of this animal using ReactiVision-tagged objects. If the player gets it right, they will get a message saying: ‘Well Done !’ and they will get one score for each correct answer they get. The player then will be able to move on to the next screen where another animal picture is shown and so on. On the other hand, if the player gets it wrong, they will be asked to try again until they get it right. This process is repeated until the last animal picture is shown. At the end you will be thanked for your participation.

Evaluation

User testing

Three children between the ages of 3-6 were chosen randomly and with no specific criteria to conduct this testing. The children were introduced to the game, and they were shown how the game will be played.

While the children are using the prototype, we observed them and noted some problems encountered without waiting from them to report it. The first one was that the children at first glance did not like the interface as it was plain colour background. Consequently we considered using picture for the background in place of colour.

As I mention adults were also involved in this user testing. Those adults were a couple of students from the university, who are not taking the module ‘Novel Interaction Design’ to avoid bias. Then, by using a satisfaction scale, we asked them to fill a form, which will help us assessing and improving our design.

We carried the task of evaluation with each...
