Learning New Tools

  • How do we learn to use new tools?

– Be taught their use by someone else -- car, bicycle, etc… – Reading the owner’s manual -- chain saw – Watching others -- vending machine – Figure them out ourselves -- CD player

  • Software designers wanting you to learn the

new tool ASAP, so they try for “intuitive” usage

– Consistent Interfaces -- build in experience – Suggestive icons -- bypass terminology – Metaphors -- exploit analogous reasoning

Metaphors

  • Some familiar computer metaphors

– Desktop (folders, inboxes, etc…) – Place (rooms, hallways, doors) – Tree (root, branches, leaves) – Stoplight (green = go, red = stop)

What does “New” Mean?

  • Most applications have the concept of a

document with:

– Attributes: date created, date modified, creator, … – Content: image, text, sound

  • “New” means create a ‘blank instance’ of a

document for this application

– A document has attributes as well as content

» All stored in one file with a place for anything » A ‘blank instance’ is simply the structure with some of the attributes filled in but without any of the content

“Click Around”

  • Software designers use standard ideas

to make applications intuitive

  • To learn a new application, check it out

by clicking around

– Take a minute to …

» Look under all menus to see operations » Follow the “…” for menu operations » Try to recognize what the icons mean

  • Clicking around is Exploration! :)

“Blazing Away”

  • Learn an application fast by trying it!
  • Beginning with a new instance,

assertively try menu items

– Expect to fail and make a mess – Exit the application and if you are asked to “Save?” reply “No” – Try repeatedly until becoming familiar

To Learn A New Tool

  • Software systems build on a consistent

interface, standard metaphors, etc…

– Expect to teach yourself applications – Do so by familiarizing yourself with the features by “Clicking Around” – Assertively try out the features, ,”Blaze Away”

  • bserving what they do

» Be efficient -- stay focused, don’t type a lot when you expect to exit

  • You also might want to skim the user

manual/help file/reference book

Online Tutorials

  • Often provided by expert organizations
  • May provide interactive tools, examples
  • Good place to find references
  • Might support a user community
  • Things to consider:

– Are they up-to-date? – Are they selling something?

Differences & Similarities

  • Different vendors will produce similar

software for the same task

– Superficially, the GUIs use similar features – Fundamentally, the task largely determines how the software must work… they must be similar

  • Implications

– If you know one word processor, you can learn

  • thers fast

– Software differences: mostly glitz and convenience – Don’t accept lousy tools, consider switching to

  • ther applications

Another Implication

  • If applications are similar at their core,

techniques can be learned without learning a specific vendor’s software

» Example: programming languages

Mac or PC???

  • Arguments about which is better, Mac
  • r PC create only create heat, no light

– They are more alike than different – Any fluent person can use both

  • I first bought a PowerMac, then a PC,

then a Windows laptop, and now this Mac PowerBook

– And I’ve owned a Sun Sparc 1+ Unix workstation

Summarizing

  • Humans must learn to use tools

– Software designers want you to learn easily

» Good software uses consistent interfaces and menus

  • Teach yourself applications by “Clicking

Around” and “Blazing Away”

– I don’t know all the features, you don’t know all the features, and that’s okay!

  • Software for a task must share core features
  • Learn applications independent of vendors
