What are the design considerations for applications designed for small screens and handheld devices?
Applications include “click to buy,” making credit card purchases with your handheld, and on-line banking and electronic deposit with via a handheld.
When looking at the design considerations regarding applications to be used on a mobile device with a screen, two key points must not be overlooked: presentation and accessibility. Presentation of an application must be done right with respect to labeling (buttons, directions, menus, etc. as to guide a user of a machine to pick their choice of selection) and visualizing (alongside labeling to further aid a user in seeing what selection needs to be made).
Accessibility of an application, likewise, must be implemented as easily as possible to aid a user in progressing through various stages, where each has their own commands and desired functions that a user must comply with. To connect with design principles, accessibility may be sometimes characterized with presentation, namely where functions that involve navigating via clicking and swiping relate to both ideals). This leads into workability which basically describes how well can an application function (start up, keep running and shut down).
To further illustrate presentation and accessibility, the apps in a smartphone provide just that; each and every app is presented in a particular shape (like a button) and within each app are menus and/or directional screens designed in a particular manner (where the font, coloring and visuals of the navigation pages guide a user in properly utilizing such app to their needs). The accessibility in swiping the screen and touching an app (scrolling bar and imitating a button respectively) adds to the presentation of the applications while appropriately giving users (a) function(s) to adhere to.
