Hi Matteo, Do you distinguish between latent 'needs' and latent 'wants/desires'? Which are you referring to? Best wishes, Terry -----Original Message----- From: PhD-Design - This list is for discussion of PhD studies and related research in Design [mailto:[log in to unmask]] On Behalf Of Matteo Visentin Sent: Sunday, 9 November 2008 6:51 AM To: [log in to unmask] Subject: Looking for referred definitions of consumer s "Latent Needs" Good Morning Community, My name is Matteo, I am looking for definitions of "Latent Need". Unfortunately I need a reference for every definition. Someone refers to latent need as tacit need, both the definitions works fine for my study purpose. I will share a final .pdf with definitions and references. Hope to receive a lot of comments. I start with this one: Latent needs - User needs which the users themselves may not have thought about but which when met, deliver delight and exceed expectations (see also Tacit needs ).
