Testing

We conducted several tests yesterday. The following structure of testers was used:

4 people out of which:
1) 2 "blinded", 2 seeing
2) 3 walking by stairs, 1 by elevator
3) 2 external, 2 ourselves

The testing process:

The system is designed for blind people to let them navigate inside a building where GPRS doesn't work and we propose a solution that uses a cane, a phone, and RFID technology.


The task:
You are coming to a reunion with your colleagues after 15 years. You haven't returned to the University ever since and you need guidance to get to the reunion hall. For this, you rely on the University's GuideMeTLU interactive system.
Your task is to go the Aula, room 342 on the 3rd floor of Mare building.

Staring point: outside the Mare building, in front of the entrance
Completion criteria: reach the Aula (room 342) on the 3rd floor
1) by elevator or
2) by stairs

You switch on the cane.
You can answer yes-no questions pressing buttons or by voice command. You can answer other questions by voice.
Keep in mind that we are not testing yourself but the device.


The findings:

• turning points should be more clearly marked with tags
• how many steps has the stairs to climb - this is not relevant as the personna knows how to climb stairs
• information about doors on the way: automatic vs manual opening,  threshold to know they passed by the door if this was already opened
• to put the tags outside room doors, not inside, and to place them perpendicular (90 degrees) on the floor to the wall
• to put more info along the way
• the fact that the elevator is difficult to use as it  needs info about buttons to press, etc
