Usability Analysis:
Learnability
Pros:
- Few options on the main screen. At the beginning, the user is only presented with two options: “buy ticket” or “plan”.(We might add a “search” option for user to find a specific exhibition or specie).
- The interface guides the user step by step to complete the tasks. It asks the user to enter answers to questions like “what date do you want to visit aquarium”, “what time”,“do you want to see following exhibitions” and “what animals do you want to see”.
- After a day is clicked, icons for all animals, sessions, and exhibitions appear. These don't have words; only pictures.
Efficiency
Pros:
- The only necessary input from the user to generate a plan is time and exhibitions.
Cons:
- Once learnt, the interface is not very fast to use.
There are hundreds of species in the aquarium, so asking the user to select which animal they want to see could be very inefficient if they want to see a large number of species.
During a given date and time, there might be multiple exhibitions, so it might also become cumbersome for user to view each available exhibition and check the checkbox if they want to visit this exhibition.
Safety
Pros:
- Only the exhibitions available during the time the user chooses will be presented for user to add to his/her plan.
- Always have a “back” button to go to previous step.
Cons:
- The interface should let the user know if he choose too many items to see for his time-budget somehow. When the user selects too many exhibitions to visit, he/she will not know until he/she hits the “Get Plan” button and then get the error prompt.Then they need to go back and redo the plan.
