Activity 3 : Interaction Details
User Interface Matrix
| Interaction Target | Spatial | Data | Material | Interaction Details |
|---|---|---|---|---|
| Mobility | ✓ | ✓ | Microphone, display screen, speakers, and switches are physically mounted on top of the mobile robot chassis. | |
| Data Management | ✓ | Motor status (moving, turned, stopped) and sensor feedback (obstacle alerts) are sent to the display/speaker to update the user |
Mobility Matrix
| Interaction Target | Spatial | Data | Material | Interaction Details |
|---|---|---|---|---|
| User Interface | ✓ | ✓ | The base chassis/wheels physically support, carry, and orient the user interface components relative to the user on the desk. | |
| Data Management | Motor status (moving, turned, stopped) and sensor feedback (obstacle alerts) are sent to the display/speaker to update the user. |
Data Management Matrix
| Interaction Target | Spatial | Data | Material | Interaction Details |
|---|---|---|---|---|
| Mobility | ✓ | |||
| User Interface | ✓ | Reads stored speed/routine parameters to drive the motors (Mobility) and retrieves stored voice alerts, reminders, or messages to output through the display/speaker (User Interface). |
