This week on LSB LiFT continues to explore the world of interaction design, from definitions to daily practice. For LSB026 Frederick Brummer sat down with Julian Gosper, a senior interaction designer at SAP, to discuss the questions we’ve been asking throughout the series – what is interaction design, how does interaction design differ from other types of design, what is the future of interaction design, and describe a typical day as an interaction designer. Julian’s detailed insight and articulate answers were difficult to cut because they were all great, so we’ve prepped a special ‘bonus question’ that isn’t part of the usual list but thought you might find interesting – how do you go from desirability to specification?
