What if you could create a self-reflective ‘mirror’, a diary that made use of our everyday thoughts to provoke us in such a way that you are able to change your future actions. As a thought experiment I devised ‘The Microtrend Diary’ during my final year on the MA Design Interactions course in 2007. Inspired by the abundance of self-help books, self-discovery personality tests and psychometric questionnaires, the Microtrend Diary is a mirror of your daily actions and emotions that reveal provocative ways to alter your future actions. This personalised diary, is printed to order based on a set of preliminary personality questions. As the owner makes a daily record of their actions, a unique set of provocative aide memoirs are revealed under a perforated flap that suggest changing your behaviour in certain ways for the following day.
