On the design of a "moody" keyboard
Alexander De Luca, Bernhard Frauendienst, Max Maurer, Doris Hausen · 2010
To counter the increasing number of online threats for users' privacy and security, this paper explores the design of an ambient security indicator, in form of a standard keyboard illuminated in different colors, and equipped with additional buttons and vibration functionality. We present the results of a focus group study, which notably influenced the design, and discuss a prototypical implementation called Moody Board.
