Eldia is a system for caretakers to help manage their time more efficiently and for the elderly to better express their needs.

Nowadays caretakers often work in stressful environment. They have to take care of the elderly without time for a break. When an elderly person needs help or have any other requests they pull a string on the wall. A caretaker receives the message but they don’t know what type of the request it is and how important it might be. This messaging system requires a lot of improvement and we decided that helping the caretakers is helping the elderly.

Design Process
We started by brainstorming and developing several ideas. Then we choose one that had the most value for the caretakers and elaborated on that. We prepared paper mock-ups of the interface and created several storyboards, these were presented to the caretakers and some of the elderly. Based on their feedback we improved our interface (e.g we changed some icons in the interface for the elderly) and dropped some features to simplify the concept. Then we went though several iterations of the GUI while drawing it on the computer screen.

We used the iPhone as a development platform. We used it in better expressing our idea to other people and using a real device helped us to pinpoint some issues (like icon/text size) very quickly. We worked together on idea and user scenarios. During the final stage Marcin was drawing the GUI for caretakers, Yves was drawing the GUI for the elderly, and Ujjval was preparing the presentation. We had internal reviews on our work together.

How does it work?
The Eldia system is a network of two types of devices. One handheld device for the caretakers and another slightly bigger one for the elderly. The caretaker device receives requests from the elderly and other caretakers, ordering them by time and priority. It also enables caretakers to check their schedule and take short breaks. The device for the elderly is an icon-based interface for making requests (e.g emergency help, food, phone call).
