After tutoring on monday I became aware of the back-button on the iPad-version looked a bit too much like a play-button flipped in the wrong direction.. This was a crucial issue because of the placement of this button: back buttons usually are placed on the top left of the screen, but this is on the bottom left. It is therefore important that this is a clear and logical button. As usual the process went something like this: Visual research, sketch and evaluate (evt. test)..
In my opinion this is now a much clearer button and symbol. You can’t mix it with a play-button, and it’s a pretty conventional version adapted to the rest of the visual style of the app..
Just to prove a point regarding pixels that fits the pixelgrid vs pixels that don’t. The upper version shows icons just placed into the document, the lower version shows version hinted to fit the pixelgrid.. The difference is especially clear on straight lines f.ex. on the top of the calendar, and the lines inside the circle..
(Hope it is clear on the site as well, and that tumblr don’t scale the images.. :P) Probably a good idea to click on the image to view it in its right format.. :)
