Posted by [Jean Femia](https://blog.opto22.com/optoblog/author/jean-femia) on Aug 28, 2013, 8:47:47 AM - [Tweet](https://twitter.com/share) *[![Automation World logo](https://blog.opto22.com/hs-fs/file-2543847027-png/blog-files/aw_logo_275x110.png?width=275&height=110&name=aw_logo_275x110.png)](https://blog.opto22.com/hs-fs/file-2543847027-png/blog-files/aw_logo_275x110.png)Automation World* magazine's David Greenfield takes a look at the future of industrial HMIs in a recent [video podcast](http://www.automationworld.com/video-podcast-industrial-hmi-trends-design-optimization-mobility). Joining him are Benson Hougland and Ben Orchard from Opto 22. Here are some of the questions they explore: - Is HMI optimization worthwhile for all manufacturers, or just those whose operator interfaces might cause disaster? - How have ideas about effective HMIs changed over the past few years, and why? - Should operators be involved in designing interfaces? - Why would a manufacturer want to provide a mobile interface? - How have tablets and smartphones changed industrial automation? - Will proprietary interfaces for machine builders disappear? Listen to [Industrial HMI Trends: From Design Optimization to Mobility](http://www.automationworld.com/video-podcast-industrial-hmi-trends-design-optimization-mobility). Have your ideas about operator interfaces changed over time? What's been your experience with mobile interfaces for industrial use?
