Couples have many communication options, but lack a common focus for couple-only exchanges. A LifeLine is a private communication channel that consolidates messages and ambient data selected by each partner, and presents it as an interactive visualization displayable on almost any device.

Lifelines’ Design and Aechitecture

To meet these needs, we propose the concept of a LifeLinea shared repository of the messages and data that partners choose to share with each other, combined with an interactive timeline visualization of the data sent by each partner, including a view of their own messages and data.
Each LifeLine acts as a private communication channel dedicated to one couple. Couples may exchange explicit messages, but may also communicate through ambient activity, with codes that only they understand.








Box-Line was designed to test the LifeLines concept with minimal communication devices.  We created a box that can sense nearby human activity and proximity to RFID-tagged objects. Data is sent via Wifi to a server, which sends it to another LifeLine device. Users can attach an RFID tag to a personal object and place it on the tray, which sends a colored nudge.

LineBuilder lets users set up a new LifeLine and select which data they would like to share. They can also
configure how their partner’s data will appear various devices, including color, intensity, symbols or dot patterns and simulate what it would look like under different conditions. For example, the user can simulate going home by moving a slider and watching the color bands darker, or click on a button to simulate a phone call.
