I chose to do complete my concept map on the iPhone – more specifically on the Photo application.
Metaphors/Analogies:
· Finger gestures. Gesturing forward with your finger progresses to the next picture while gesturing backward returns to the previous picture. Pinching in or out will zoom in or out of the photo, respectively.
· Tilting the phone: Turning the phone from landscape to portrait changes the orientation of the photo as well, as though you were actually turning the photo.
Concepts:
· Using the accelerometer to change pictures.
Relationships between concepts:
Using the iPhones built-in accelerometer, one could simply motion the phone to the right or to the left to advance or return to a photo. This gesture with the physical phone would be combination with or in place of the finger gestures as mentioned previously.
The Mappings:
The simply gestures within the iPhone are designed to allow users to intuitively change features or presentations with one’s finger. By swiping it forward, the photo advances. With respect, a simple flip of the wrist forward could also perform the same action. Apple already uses motion control to interact with many other features of this device, so the implementation would not be difficult.
The device could provide feedback to the user as well, notifying them what picture they are currently viewing and how many photos are left in their respective directions. A new gesture of a circle on the screen could also bring up the photo index, allowing the user to select any of the photos within their library instead of turning the phone to the portrait orientation and pressing the back button.
