Mobile Device Screen Size and UX

For a device with a small screen, you must limit the number of features to those that matter the most for the mobile-use case. Even on desktop computers, precious pixels are the world’s most valuable real estate.

These wise words, no-brainers to some, come from Jakob Nielsen and Raluca Budiu’s Mobile Usability book (p. 52). The authors highlight the need to balance available screen space with the amount of information that is presented; too little as well as too much information will create a poor mobile user experience.

How to determine what’s appropriate?

  1. Conduct user research to determine requirements for design
  2. Follow design best practices in the mobile user-centered design philosophy
  3. Conduct heuristic evaluations and usability testing
  4. Tweak design based on insights from step 3

 

Debunking Myths about Data-driven Design

This article from UX Magazine addresses the following myths about data-driven design:

  1. Data = numbers
  2. Data is the truth
  3. Bigger is better
  4. Designers do not need data
  5. Data and innovation don’t mix
  6. There is a right (and a wrong) way to use data in design

The author Pamela Pavliscak argues that quantitative data from A/B studies or analytics are not always sufficient to inform design for a great user experience; she proposes that utilizing insights from qualitative data is as important (if not more!) as relying on quantitative measures.
