Suggestions for solution
Obvious which content is the map
Recognition rather than recall, Match between system and the real world
Use of Google Maps - instant recognition and familiarity
Recognition rather than recall, Consistency and standards
Was looking for browse for buildings (because I am not Ed or going to school at Yale - what do I search for when I do not know the name?). Must know the name of the building - if you do not, there is no alternate browse mode
Recognition rather than recall
Provide a "directory" of campus buildings and locations for users who may not know the right name from memory
Cursory help is provided with "how to search" instructions
Help and documentation
After doing some of my own research, I found a Yale building named "Founders Hall"; using this as a search input brought up the correct result. From here I could get directions from another location (like Ed's dorm, or a parking lot)
Flexibility and efficiency of use
Founders Hall was linked in the location callout of Google Maps. I clicked on it to get more information. This resulted in sweeping me away from the portal and the Google map to a Yale webpage with a wholly different map interface. This map interface seemed to be in its default state as it did not show/highlight/focus Founders Hall (what I had clicked on). I was confused, but assumed that the Google maps interface was limited to addresses and that further information (and detailed campus maps) could only be given by this other (apparently Yale-developed) map application. Disappointing.
Visibility of system status, Error prevention
Inform the user when they are transfered to another interface. Capture search input from the portal and pass it to the secondary map application. Make the Yale map application and the Google map portlet match as much as possible.
Map, Transition Alerts
I will not go into the Yale map application, but will note that there was no way to get back to the portal from this interface (it had spawned in a new browser tab, however).
User control and freedom
Provide a means to return to the portal
