First of all, you need to let people know the topic of your
research in order for them to help you.
Why don't you conduct a literature research and come out with a
list of who has done what? Explore their differences and
similarities. Identify what is missing or what are the areas you
can or want to improve on.
Use the area which you identified from the literature research to
form the purpose of the project. From there, you can determine your
aims/objectives of your project. What kind of results are you
expecting?
Next to follow will be the proposed methodology. That is how will
the experiment be conducted.
As you have not conducted any experiments, perhaps a gantt chart
showing the FYP progress will be useful. Using the gantt chart, you
will need to show that what are the work you intend to carry out.
That should be enough for your interim report.
You will need to discuss with your supervisor on these and see if
there is anything you will need to improve on.
