2) Is there any guideline for the font and button size for
touchscreen PC
application?
Based on some research done at MIT, I recommend in general 1cm square/
circle as a good target for finger pads (what is most likely being
used to touch/press). Adult human finger pads are roughly 8-12mm wide.
4) Since it is multi touch application, can we eliminate zoom
icons/indication/buttons? Also right or left scroll arrows?
Or should we retain them but represent them in a more subtle manner?
Often people keep visual cues/affordances/controls and supplement them
with gestures. The gestures act as shortcut keys. For instance,
tapping an arrow to scroll or you can do a swipe.
6) We have placed the recycle bin to the bottom left hand corner.
User needs
to drag and drop the items to the recycle bin in order to delete.
Would you prefer a change in position (considering drag and
drop) , like
top left hand (like in windows 7)?
That's probably the 2nd most difficult place to access for the right
handed (93% of the population) because of the reach. (Top left #1.)
Fitts' Law still applies.
