When roaming the wards, SOFA projects two baby-blue eyes and a pixelated smile on a small screen, though it can show a range of positive emotions, from surprise to love. A second screen sits on its waist, allowing doctors to remotely share a patient’s medical records. Its jointed arms and fingers serve no medical purpose, but according to Laowattana, patients would rather communicate with something that looks like themselves. When interacting with patients, SOFA replaces its digital smile with a video of the controlling doctor, reminding patients that a human is still in the driver’s seat.
