Week 6 - Exercise/Basic Interface

Exercise:

Create CRC cards for a scenario (or 2) you what to test in future prototypes. What is a testing scenario that you want for your concept?

The user tries to open the bag, the camera sees that the user is not the rightful owner and the alarm sounds. The opposite case should also be tested - with access being granted.

What are the nouns (objects) in the scenario?

The user, the bag

What are the verbs (responsibilities)?

Scanning, stealing

Who are the collaborators?

The user collaborates with the scanning system which also collaborates with intruder’s information - face, identity etc

Basic Interface:

For the first interactive prototype, it will be split into two sections: the detecting interface (the bag) and the mobile interface which further alerts the user of intrusion and is a companion to the main system. It will first display a graphical representation of the bag and prompt the user to unzip the bag. The user will then unzip the bag by clicking and dragging a zipper element on the screen and following an arc motion, as is the case for backpacks. The disturbance of the zipper will trigger the face scanning system to kick in (this will not be implemented in this prototype however) and then sound an alarm and a flashing light to indicate if it was an intruder (or granted otherwise).

The main point of this prototype is to demonstrate the interaction of unzipping and receiving the feedback of the alarm system. The final idea (described above) does not contain facial recognition and depicts an interaction between a single user and the system. The storyboard below illustrates a previous iteration of the idea, and involves the user playing both roles of owner and thief:

1. User ‘uploads’ their face
2. User opens the bag and sees it’s a match
3. Now user plays thief and is told to try to unzip the bag
4. It is not a match and the system sets off an alarm
5. This is also displayed on the phone, which the user can dismiss, and can also press a button which automatically takes a photo from the bag. Perhaps there is a timer, and if the user clicks the button to ‘turn around’ within a given timeframe, the thief can be caught
6. A screen displays if the thief was caught (and a picture if one was taken) or had gotten away.

This is probably too complicated and too technical for this prototype. It should focus on and test a single interaction, rather than incorporating too many interactions, and facial recognition could be omitted. How can a thief's face be detected then? Perhaps there could be randomisation.
