Drag and Drop - Money Interaction
I'm trying to make an interaction where the learner would drag the appropriate coins to a table to make the correct amount of change. I had originally created the interaction with a text entry box where the learner would just enter the correct amount of change, but I would like to more realistically simulate how waitresses/waiters make change by counting up.
I want to be able to use the same coins multiple times. For example, if making change from $40 for 35.60, I want the user to be able to drag two toonies ($2), one quarter, one nickel and one dime to the table.
The learner could also drag four loonies ($1), and four dimes.
Any ideas on how I can accomplish this.
- To use coins multiple times
- To allow correct multiple solutions
Any ideas would be appreciated.
