Human-Centered Design

David Kelley on human-centered design | Video on TED.com

In this video David Kelley mainly talks about how product design has become much less about the hardware and more about the user experience. In the last 18 years people started to focus more and more on human approach to design. Back then designer used to make 3d models or 3d renderings to communicate their ideas but nowadays they got those objects that they're designing and get them emotion showing how it will be used by making interactive prototypes that show man-machine relationship.

To demonstrate the idea of human centred design David give some examples and i think the most interesting one is the interactive system and data infrastructure designed by him for Prada New York store. So how it works is that every products displayed has a RF tags and if we see something we interested in , the staff can scan their tags and they can be displayed altogether at any screen at the store. In the dressing room there are also scanner and touch screen where we can get access to detailed information about the merchandise we are trying on. Another feature is the liquid crystal glass in the changing room that becomes opaque if we step on the button and it switches easily to transparent glass on another button so other people outside able to review the products while we try them on without we leaving the dressing room. Lastly there are also magic mirror which operates in 3 seconds delay so when we are trying cloths we can turn around and see how it looks like on the back when we turn around on the magic mirror. The design includes data infrastructure that allows all staff to develop better understanding of future costumer needs. This whole design use technological advances in order to make an interactive atmosphere between buyer and the store so the customers are having an enjoyable shopping experience.

This video reminds me that we often put too much focus on the product and pay less attention to the user itself. The idea of design is to make human life become more enjoyable and better. When we focus too much on the products, certainly technological objects, it can be say that we forget the idea of designing. It's really good nowadays human behaviour and personality has been considered more in the process of designing products. It's important for designers being reminded not to carried away with technology and make products so high tech just to make it more fancy instead of really consider human behaviour and personality as the users.
