Comments Posting comment... By: hkahle (4 month(s) ago) Hello John, I am a Human Factors Specialist employed in the Investigation Division at WorkSafeBC (OH&S Regulator in BC). I am a Graduate of the M.Sc. Human Factors and System Safety Prgram taught at Lund university in Sweden (former student of Sidney Dekker). My two colleagues and I have a similar mandate in that we are trying to bring HFE to workplaces all across British Columbia. I see you have used a terrific set of insutrial examples in your presntation that is very well structured for a new audience. John, I would very much enjoy the opportunity to follow-up with you and the work that you do. I will send you a LinkedIn invitation. I would like to request the download of this HFE presentation that you have created. Would that be possible? Thanks very kindly.

Designing things or processes to fit human abilities and limitations Designing the glove to fit the hand, not the hand to fit the glove (supporting/improving human performance by as little as 3-10% will make things much safer) Using specific ways to uncover hidden needs, assumptions and unexpected interactions (“heuristic evaluation”, “usability testing”) Taking advantage of knowledge about human capabilities (5 senses, communication styles, ranges in physical size and strength, etc.) Human Factors Model: Human Factors Model Senses - Vision - Hearing Psychomotor - Hand - Eye movements Input Devices Keyboard - Voice recognition Output - CRT - Sound INTERFACEHFE and Healthcare: HFE and Healthcare Academia University of Wisconsin (BME-IE) Catholic University in DC (BME) Government FDA-CDRH (great web site) NIH-NCI usability for patient information (www.usability.gov) Industry Medtronic (over 8 years) Baxter and Abbott (more recently)How good are we at vigilance/ paying attention?: How good are we at vigilance/ paying attention?Performance Graph : 100% 90% 80% 70% Time (hours) 1 2 3 4 Performance Performance Graph Performance Graph : 100% 90% 80% 70% Time (hours) 1 2 3 4 Performance Performance Graph How can we move the curve up (improve performance)?: How can we move the curve up (improve performance)? 100% 90% 80% 70% Time (hours) 1 2 3 4 Performance How fast can we learn things?: How fast can we learn things?
