Picture This
A connected picture frame displaying historic images
Ideas / Iterations
- Download the pictures to the Raspi and display one of them (warmup)
- Slideshow and turning the images 90° to adapt to the screensize
- Play around with potentiometer and Arduino to bring an analog input onto the Raspi (which only has digital I/O)
- Connect everything and adapt the slideshow speed with the potentiometer
- Display the name (extracted from the filename) below the picture
next steps, more ideas:
- Use the Raspi Cam to detect a visitor in front of the frame and stop the slideshow
- Use the Raspi Cam to take a picture of the face of the visitor
- Detect faces in the camera picture
- Detect faces in the images [DONE, manually, using online service]
- …merge visitor and picture faces
Story
- Our smart frame shows police photographs of homeless people by Carl Durheim (1810-1890)
- By looking at a picture, you trigger a face detection algorithm, analysing both, you and the homeless person
- The algorithm detects gender, age and mood of the person on the portrait (not always right)
- You, as a spectator, become the judge / part of the system / algorithm
- The person on the picture is at the mercy of the spectator, once again
How it works
- Picture frame has a camera doing face detection / presence detection
- Pictures have been pre-processed using an online cloud service
Questions (not) answered
- Who were those people? Why were they homeless? What was their crime?
- How would we treat them? How will they / we be treated tomorrow? (by algorithms)
