Our team of UC Berkeley students, in partnership with UCSF hospital, created a smart lighting and ambient environment controller to lower delirium rates and combat patient loneliness.
The controller consists of potentiometers, toggle switches, and push buttons, wired to a RedBear Duo and Raspberry Pi. All the electronics are housed in a 3D printed and laser cut enclosure. There are 4 main features: manual mode, day/night mode, postcard mode, and environment mode.
Patients and hospital staff can use the right-hand set of buttons to control the settings of LIFX lightbulb. Other wifi bulbs are also compatible. In manual mode, the color and brightness can be adjusted as desired.
In automatic day/night mode, LUMOS emits cooler blue light during sunlight hours and warmer less disruptive light during the evenings to help regulate the patient’s circadian rhythm and alleviate disorientation. For this setting, we programmed the color temperature and brightness in a 24-hour cycle based on the time of day and information from a weather API.
The left half of the LUMOS controller interfaces with the projector and speakers. Postcard mode is a PHP-backed web portal that allows remote friends and family to log on and upload images that are displayed as a slideshow in the patient’s room. With this feature, patients feel less lonely and feel more connected to loved ones.
Using the LUMOS controller, patients can also switch to environment mode to experience the sights and sounds of various ambient scenes. The projection can also be displayed cleanly on a wall, but can just as easily be adjusted to be projected on a ceiling or a screen.
