A connected picture frame displaying historic images

1. Download the pictures to the Raspi and display one of them (warmup)
2. Slideshow and turning the images 90° to adapt to the screensize
3. Play around with potentiometer and Arduino to bring an analog input onto the Raspi (which only has digital I/O)
4. Connect everything and adapt the slideshow speed with the potentiometer
5. Display the name (extracted from the filename) below the picture

next steps, more ideas:

1. Use the Raspi Cam to detect a visitor in front of the frame and stop the slideshow
2. Use the Raspi Cam to take a picture of the face of the visitor
3. Detect faces in the images [DONE, manually, using online service]
4. …merge visitor and picture faces

• Picture frame, shows police photographs of the homeless by Carl Durheim (1810-1890)
• Who were those people? Why were they homeless? What was their crime?
• Picture frame has a camera doing face detection, but does not reveal that
• Instead, a spectator looking at the frame triggers face detection on the portrait
• Face detection algorithm (in the cloud) detects gender, age and mood
• Spectator becomes the judge / part of the system / algorithm
• Person on the picture is at the mercy of the spectator, once again
• How would we treat them? How will they / we be treated tomorrow? (by algorithms)
