Changes to Interface Reverse Up/Down button in card selection Added # of Players Screen Help Window Menu should not cover button info Restart Button in middle of hand

Reverse Up/Down Button Problem: User found it unintuitive that up decreased the card rank and down increased the card rank in our card selection system Change: Reverse the functionality of the up/down button Design Principle: Match between system and the real world

Added # of Players Screen Problem: User forgets to update the # of players almost every time. Change: Added a screen specifically to prompt user to update the # of players. Design Principle: Error prevention

Help Window Problem: User didn’t know how to some parts of our interface and got lost. Change: Added Help Window when user pressed # Design Principle: Help and documentation

Menu should not cover button Problem: Menu was covering the Select word above the confirm button. User did not know what exactly the confirm button did. Change: Moved menu so it no longer hides the Select. Design Principle: Visibility of system status

Restart Button in middle of hand Problem: Hand ended before the river and there was no way to restart the game without continuing or hitting Undo till the beginning Change: Added clear button which returns to the first screen anywhere in the process. Design Principle: User control and freedom
