The map balloon shows these 4 things:
- The assignment #
- Questionnaire and version
- Type of assignment
- Button to start the interview
The interviewer will reach the marker and then verify if the physical house and the assignment match (GPS locations can be off). They have no information to verify. They have to start the interview to do this.
I would like to see a few identifying questions in the balloon. Are there use cases where the assignment no is useful to the interviewer. Also for an assignment that has been marked on a map, there a high chance that it is a single interview assignment. These two can be replaced by 2-3 identifying questions. And/or touching the balloon can expand it to expose more variables.
