Recently a trainee asked me – How do we go about plotting a sine wave?  We were doing a basic ActionScript course and I was explaining the Drawing API, and how we could easily draw circles and rectangles etc. We then got into working out distances and I mentioned that it is all down to Pythagoras’ theorem, and from there we talked about cosine and sine and the question was  - How do we go about plotting a sine wave?

Well, drawing anything in ActionScript 3 can be accomplished by the lineTo() function, and it would have to run off an ENTER_FRAME event, so that gave us the skeleton functionality of our code…  Read more...

Recently I commented on the fact that the book Rapid Development with Adobe Captivate 5 for Windows devoted six pages to a technique for producing different sized versions of a Captivate project. That got me thinking about how important it really is to choose an appropriate width and height setting for Captivate projects.  Read more...

I recently purchased and read a new book on Adobe Captivate 5.0 called Rapid Development with Adobe Captivate 5 for Windows. The title was one of the things that drew me to it — it captures the spirit of the product (Captivate itself) very well.

It’s a strange book: in some ways it lives up to the title, in that it cuts to the chase and contains very little superfluous information that might bog you down. After a succinct summary of the rapid development workflow that the authors recommend, it gets straight into the practical business of how to record and create projects. It’s also packed with a large number of “professional tips and tricks” that are usefully listed (with page numbers) in the table of contents.  Read more...

The McGurk effect

The McGurk effect is basically when what you are seeing overrides what you are hearing.
For example, you are hearing one sound, but the brain receives (at the same time) some visual information and decides to override the auditory information and your brain ‘hears’ another sound. The sound itself never changes, it is just your brain making the change.
Here is a great video showing you the effect. Watch this and see what you think, and also listen but close your eyes at the same time and you will see that the effect goes away – really amazing!
This has implications for animation, but it is really fun to watch!  Read more...

How do you use your iPad or iPhone? With the iPhone being so popular, and now the iPad, I have found a couple of links that I wanted to share with everyone. These links made me laugh or go wow- and I will leave it to you to judge whether the last link is real or not.
