eBay Australia is hosting a two-day Innovation Lab for 3,000 people at Darling Harbour in Sydney this weekend featuring cutting edge technology including virtual reality, holographic projection systems, 360 video and of course several 3D printers. The goal of the Innovation Lab is to closely monitor the public as they interact with the technology and see which products get the best response. Visitors interest will be gauged using gaze monitoring, dwell time and a series of mobile questionnaires. Once all of the data has been collected eBay plans to share their findings with their retail partners and eventually will publish the results online.
