How to achieve ldquouser-friendlinessrdquo in computer design

bull HCI Scopebull Use amp Context Find application areas for

computersbull Human Study psychological amp

physiological aspects eg study how a user learns to use a new product study human typing speed

bull Computer Hardware amp software offeredeg input amp output devices speed

interaction styles computer graphics

bull Development Design implementation amp evaluation

HCI

HCI Goals

bull At physical level HCI concerns the selection of the most appropriate input devices and output devices for a particular interface or task

bull Determine the best style of interaction such as direct manipulation natural language (speech written input)

bull WIMP (windows icons menus pointers) etc

Develop or improve1048707 Safety1048707 Utility1048707 Effectiveness1048707 Efficiency1048707 Usability1048707 Appeal of systems that include computers

bull Safety protecting the user from dangerous conditions and undesirable situations

bull Users1048707Nuclear energy plant or bomb-disposal ndash

operators should interact with computer-based systems remotely

1048707 Medical equipment in intensive care unit (ICU)

bull Data Prevent user from making serious errors by reducing risk of wrong keysbuttons being mistakenly activated

Provide user with means of recovering errors

bull Ensure privacy (protect personal information such as habits and address) amp security (protect sensitive information such as passwords VISA card numbers)

HCI Goalbull Utility extent of providing the right kind of

functionality so that users can do what they need or want to do

bull High utility Scientific calculator provides many mathematical operations built-in formulae and is programmable

bull Low utility Software drawing tool does not allow free-hand drawing but supports polygon shape drawing

bull Effectiveness concern a userrsquos ability to accomplish a desired goal or to carry out work

bull Find a master thesis in our library Web

The Impact of HCI Productivity Increases Reduce training workshop etc Prevent employees taking Satisfaction Good quality and good product
