IT support for elderly people with visual impairments
A woman with Down syndrome and dark hair is sitting in front of a bright window in a beige armchair, in front of a modern wooden coffee table. On the table, there is a glass water carafe and a vase with dried flowers. The window is lit up by the sun, and one can see a road or a parking lot with some cars that are out of focus. The woman has headphones in her ears and a laptop on her lap, and is speaking with someone on her computer.
  • Digital inclusion

A resource bank for disability simulation
Two individuals are playing video games together, focused on a screen outside the frame. On the left is a woman in a wheelchair, wearing a beige hoodie and black pants, with long hair gathered over her left shoulder. On the right is a man seated on the couch, wearing glasses, a red plaid shirt over a white t-shirt, and blue jeans. He appears to have Down syndrome. Both are holding game controllers and seem to be having fun while being engaged in the game.
