Reminder signals help to remind a person to drink, but are often experienced as obtrusive and impractical in everyday life. We designed Illuminated Ring, a wearable display that supports fluid intake in that it displays the time elapsed since the last drink via single point lights. In a user-centered design process, we developed an interactive ring, which we evaluated in an exploratory field study. Initial results show that Illuminated Ring is perceived as an unobtrusive display which can help to drink sufficiently.enWearable DisplayPoint LightsRingFinger-wornAmbientFluid IntakeUser Experience DesignPrototypingInteraktionsmodellierungInteraktion mit eingebetteten und ambienten SystemenMobile und ubiquitäre InteraktionWearable und Nomadic ComputingBe-greifbare InteraktionText/Workshop Paper
