MOBILE DESIGNOR (Device Limitations (Screen Size (Phone Screens can…

- - - - Larger Screens aren't necessarily the solution as the "reach" of users limits the usability of bigger screens

        The accessibility of each zone is denoted by colour
        
        Indicates the zone of reach on a standard mobile phone
        
        TIP use fixed navigation footer
        
        Zones: Natural- Green, Stretch - Yellow, OW( Out of Reach) - Red
        
        TIP design for the flow of the thumb zone
        
        zones Change form depending on hand/s used
      - Major limitation
      - Error prone
      - Splits attention between keyboard and content
      - Keyboards take up a lot of the screen as buttons must be fingertip sized
  - - - Content Displayed on a 30 inch screen will require 5 screens on a small 4-inch phone screen
      - "Above the Fold"
      - Higher interaction cost on phone to access the same amount of information as PC
      - Mobile Content is "Twice as difficult"
    - - Whenever a new design element or a piece of content is included, something else gets pushed out or "below the fold"
    - - Denotes the user-interface elements that are instrumental in using a site or applciation
      - users come to a site to find information rather than contemplate the beauty of elements
      - Content is always of interest
      - Designers need to accommodate a high content-to-chrome ratio on the mobile screen
  - - - Support Offline Usage
    - - Waiting time depending on connection speed
      - As few back and forth trips between client and server, light pages with as much information as possible
      - Minimize number of steps, to reduce page loads
  - - - Impractical, even on tablets
    - - Tasks should be easy to complete in a single screen or webiste
      - Users should not have to leave the app (or website) to find information that the app requires but doesn't provide.
      - Moving information between apps is error prone and a NONO
  - - - Interruptions are common
      - Usually on the go
      - Phones follow us outside
      - Average phone usage session is 72 seconds
      - We must design for interruptions
      - Save State
        
        Pause and Resume at will
        
        History, return to previous choices.
  - - - Usually the most limiting factor in mobile devices
      - Optimize applications to minimize their power footprint
        
        Only use listed sensors/ functionality when absolutely necessary
        
        Reading and writing to memory
        
        Network traffic and things like GPS
        
        Backlighting
- - - - Context with a "Capital C"
      - Helping the user to understand a task they are currently performing
      - Provide an understanding (Context) to the users task at hand
