My type (1) questions on my design of the experiment

Hi, prof. Tsai

I got some problems for my experiment design. I am not sure if this belongs to t-test or something else.  
I am still learning statics from udacity 
I wish to be familiar with these methods

My questions can be classified into two types:  technical and methodological

Let me describe my technical problems first. 
There're four of them in total.
  1. ppt ratio
  2. How about the background color? (Mine is like grey mixed with a little bit of yellow)
  3. shall I remove the bookmark and the status bar?
  4. And after all, is ROI the suitable tool to detect such a subtle process on syntax parsing / clause parsing? 

On Thursday you mentioned the way we use to make ROI map in powerpoint/ keynote
But I found that our monitor is wide-screen with different ratio (16:9 or 16:10)
If we export the ppt file to PDF, the background (and the foreground pics )would be in different ration.
We should decide the ratio of the ppt before we export it to PDF.
I suppose we shall fix it to 4:3 ? Even if ti's exported to PDF and display on a wide-screen monitor like iMac, it will remain the ration 4:3 instead of being stretched.

Since we need to do color indexing, the color of the background shall be taken into account.
(I just knew this on this Thursday. )
But I guess it's ok to assign the background a color number since What we're interested in are only the ROIs.
To make the background color not white is quite important, this will make the reader blink less or read better on the monitor.
So I think I would keep the background, is that ok, prof. Tsai? 

Finally for the ROIs:
I am looking for the parsing pattern change in the help of mnemonic devices in sentences. I suppose the readers will find that the main idea in each sentence lies after the verb, the so called "depiction part" of a sentence. These m-devices are there to help them figure this out. 
I assume they will speed up after a few pages of training. They will go directly to the red underline parts of the sentences, which are located at the rear part of sentences (after the main verbs).

If we put ROIs on the main verbs, can we detect their eye movement to the rear part of main verbs? 
What shall I do to do such detection? 
As for the additional elements: 
I am not sure if the bar at the bottom of the pic will effect the reader. Maybe I should remove it, or just let the reader know that there's an unimportant bar so they won't look at it at all. The pictures are captured from my cellphone (as an E-reader) so it has a bar there.  
I found you notice Zuzana's page number at the bottom right. So I think I might have the same issue. 

As for another type of methodologically problems:
I think I would wrote another letter since this one is long enough~
