1. Problem Statement 

Wiki MarkupThe New England Aquarium offers complete and detailed information regarding its exhibitions and locations through its [website|http://www.neaq.org/index.php], maps (see Image \ [2\]), and even interactive screens (see Image \ [3\] and \ [5\]) in the building. However, due to the large number of exhibits and animals (and more importantly, how they relate) coupled with the complicated and non-intuitive layout of the interiors, a simple task, e.g., finding a specific animal like the [little blue penguin|http://www.neaq.org/animals_and_exhibits/animals/little_blue_penguins/index.php] in the museum, can be daunting and time consuming. Visitors usually have limited time budgets and come in with very little planning. Most of them try to obtain as much information inside the building as possible in order to find what they are interested in visiting, attend various exhibitions, and successfully cover most of the like the little blue penguin in the museum, can be daunting and time consuming.

Difficult tasks

  • Successfully traveling the building and finding everything.
  • Accessing information regarding where exhibits are (e.g., which tank has a specific animal, or where/when will an exhibition take place).
  • Creating and changing schedules on the fly in order to see multiple sessions in one visit, specially for the information sessions with expert staff.

2. Observations

A set of passive observations were conducted in different parts of the aquarium during two trips covering both weekdays and weekends for a total of approximately five hours in total. This allowed us to find some interesting problematic aspects of the visitor's experience.

The aquarium has different tanks an uncovered animal ambients in which the aquarium staff conduct exhibitions and informative interactive sessions about the animals. These exhibitions are conducted in several places at the same time and are very interesting for visitors as they allow for one-to-one conversation with experts. The staff members have a broad knowledge about the exhibitions, which attracts many visitors with questions. We noticed the schedule for these sessions is hard to find once inside the building. In fact, unless a schedule is prepared in advance, visitors are very likely to miss most of the exhibitions as they have close and overlapping times. Moreover, the interior layout of the building is very confusing. In other words, even when looking at a map that tells you exactly where you are and where another area is located, it is very difficult to get the intuition regarding how one must move within the building to get there. This is a problem that is hard to solve and even explain. However, CSAIL students can easily relate as the Stata Center has the same problem.

Wiki MarkupThe aquarium has an interactive touchscreen wall with information regarding the animals. One would think that this could be an interactive aid to find information about animals-sessions-places, but we only found information about some animals. The way the system work is by presenting a set of moving bubbles with the picture of one animal inside (See Image \ [3.a\]). After selecting one bubble, an information pop-up is shown with short information about the animals (See Fig. 3b). In some of them it is possible to keep navigating and watch videos and pictures (Image \ [3c\]). This seems to be a good idea, however, we found several problems from the usability point of view. In terms of visibility, the bubbles are very small as well as the animal picture and the font size and the icons presented in step 2 (Image \ [3b\]). This affects the perceived affordances and because of that learnability is not very good.

Visitors expected more information from these interfaces such as where to find the each one of the species presented and also information about information sessions schedules.

options that lead to (c) more information. (d) Other devices have external keyboards.

Each tank has a a signboard with all the species on it. However it could be a challenge to match them because of lack of visibility. Font sizes are very small, contrast is uncomfortable, location is inconvenient and these problems are exacerbated when there are many visitors in the place.

3. Interviews

We conducted 3 interviews with the users. 

...

Parents with a kid of 8 years old on weekend. They didn't buy the tickets in advance but while doing the long line to buy them, the staff informed about the access to the express line if they buy the tickets online using their cellphones so they did. The kid wanted do find the little blue penguins (which are advertised all over the place) but they were temporarily moved to another place and it was time consuming to find them. The parents where interested in teaching science facts to the kids but it was difficult to read from the information on the walls so after a while they got tired.

Lessons learned:

...

  • Specific species can be temporarily moved and this makes even harder to locate the right place given that the maps in the walls are static (Image \[2b\]).
  • Lines during weekend for buying tickets can be considerable longer than on weekdays. The staff tries to solve that by informing them about the website but we observed that only few people actually responds to this information.
  • Parents with kids are a very frequent user class on both weekend and weekdays. 
  • Comment: for buying the tickets from your cellphone, you need to register in the website which is inconvenient. 

...

  • Tourists:
    • More frequent on weekends
    • Groups with sizes ranging from one to three families.
    • Have very limited time budgets.
    • Usually no scheduling or planning is done beforehand.
    • Have greater difficulty finding information through staff members and rarely discover interfaces
  • Locals:
    • More frequent on weekdays.
    • Usually visit for education-recreation of kids.
    • More time available to spend in the Aquarium.
    • Some of them are already members of the aquarium.

Image 5: Adults tend to ignore the interactive screens because they don't assume

they have that purpose. Once discovered, most struggle with the small, hard to read

buttons and give up entirely. We saw that children usually discover the usability

quickly as they tend to touch everything. However, they don't seem to gain any

information as they play with the screen randomly.unmigrated-wiki-markup

These classification according to different parameters are related related with the day-of-visit parameter because some of this classes are more likely to visit the Aquarium in particular days than others. Image \ [6\] shows the observed behavior.

It is also possible to identify the distribution of these classes considering their time-budget and planning behavior. Image \ [7\] presents this information graphically.

3.2 Staff

We didn't have access to interview the staff during these visits because it's necessary to be authorized first. However, after observations and getting familiar with the dynamics of the staff that is visible to the visitor, we can anticipate the following main user classes relevant to the problem we are analyzing.
