What are the types of driver interaction with the vehicle? –Source of power–Guidance (Controller)–Sensor–Occupy space in (or around) the vehicleA Central Tenet•Human Factors must be accounted for every person who comes in contact with the product–Manufacture (including sourcing)–Operation–Innocent Bystanders–Maintenance and Repair–Disassembly and disposalHuman Factors and Industrial Design•What are some examples of good Human Factors Considerations in a product?–Simplicity–Reliability–Good documentation–Style–Comfort of use•What are some examples of bad human factors considerations?–Low quality parts–False adverts–Badly written manuals–Excess useless functionalityHuman Factors and Industrial DesignDiscussion•3 really bad designs–Plastic lawn chairs–The Honda element–Hummer II–Airline seats–Remote controls–Women’s shoes–Extreme Fashion •Why do they stink?–Poorly thought through–Does not appeal to masses•What was the designer thinking of?–Cheap–New–New segment–Difference between designer’s goald and users needs–What you would do to improve them?•Industrial Design –Creating and developing concepts and specifications that optimize the function, value, and appearance of products and systems•Human Factors (or Ergonomics) –Those aspects of the product that relate to human interfaces including•Ease of use•Ease of maintenance•SafetyIndustrial DesignDefinitionsEase of Use•Friendly interface between mechanical/physical and human worlds–Communicates function intuitively–Short time to learn–Retention of knowledge–Ease of apprehension by five senses–Psychological satisfaction•Some questions to ask–Is the product intuitively easy to use if the manual is lost?•Displays•Operations•Controls–The virtue of simplicity.–Can the product be used by the intended user?•Forces required•Motions required•Thought requiredHuman Factors and Industrial DesignAnthropomorphic DataAre all people the same?Human Factors–What are some of the ways the product could be used or misused (by the user or anyone else such as children) that are unsafe. Can you make the product use robust against these modes?–Is the product itself robust against misuse?–Is there only one obvious way to use the product?–Varying complicating external conditions•Climate•Culture•Other contextual infoExamples: Consider I/O devices –Particular questions in Guatemala?•From last year–Starting point an IV unit with no flow control–A filter which appears to work “well” even though it is not working at allHuman Factors and Industrial DesignMisuse•Think through the ways the product might be misused (renders the product ineffective or even dangerous)–Can the product be designed to discourage misuse? –Examples of misused products2 second tentMIT 100 buck computerMilitary tourniquetApply to your product•Today•For your projects, each team takes 10 minutes and gives some of your thoughts on industrial design considerations–People who “touch” product–Ease of use–Misuse–Safety•2 minute presentationHW•Midterm (on website)•Written 10 page submission as before•PPT presentation <10 minutes–Where you are–What you will do by the end of quarter–Plan for work until end of quarter•Think about prototype (no deliverable)What form should the prototype take?•Paper?•Scale Model?•Mock-up?•Simulation?–Additional info to be supplied by Oscar Arce who will be next Thursday’s lecturer on
