Developers: Why Care About the User?

Developers: Why Care About the User?

As developers, we deal with technologies, frameworks, and data, making it very easy to forget that what we create is meant for real people to use.

While designers and UI specialists should handle most decisions about how a product or service looks and feels, we should all be on the same page to make better solutions. Whether we are building an interface for a desktop website, mobile application, or chatbot, what are some basic design concepts that we as developers can pick up, allowing us to be on the same page with designers and product owners during product meetings and discussions?

Other Decks in Technology


  1. @malekontheweb We need users to support ourselves and our •

    passion for development… “…the most common activity at Web sites is • fleeing the Web site” Edward – Tufte Yale Professor Emeritus – http://www.nytimes.com/ – 1998/03/30/business /the-da-vinci-of-data.html
  2. @malekontheweb • “People judge an experience by the most intense

    point and the end point.” –Dave Rothschild –iOS App Developer, Intel –http://bit.ly/2lutWqr
  3. @malekontheweb • To encourage people to use our product, we

    must understand: • In most cases: “You are not the user” • Must empathize, understand: –Their needs and desires –Their concerns –Their skills and difficulties
  4. @malekontheweb • “Approximately 14 million Americans aged 12 years and

    older have self-reported visual impairment defined as distance visual acuity of 20/50 or worse.” –Center for Disease Control – Vision Health Initiative • https://www.cdc.gov/visionhealth/data/national.ht m
  5. @malekontheweb • Condensed fonts – fit more on page, harder

    to read • As opposed to this non-condensed version • Light-gray on white is not easy to read • Use contrasting colors • 8-point text is too small • Increase point size – experiment
  6. @malekontheweb “The Academic Evidence Base for Typeface • Readability” Links

    to various readability studies – http://typoface.blogspot.com/ – 2009/08/academi c-base.html WebAIM • Color Contrast Checker http://webaim.org/resources/contrastchecker/ –

  8. @malekontheweb OTHER DESIGN CONSIDERATIONS Left • -to-right - Right-to-left -

    vertical? Leave enough room in UI for larger texts? • Or will UI have too much whitespace if – translations are smaller? Don’t include text inside images • – or will require new images when translating
  9. @malekontheweb • Always test with target audience • Again, be

    careful if color is only signifier • Choose icons understandable by different cultures • Icons may need text labels if ambiguous – consider “5 second rule” https://www.nngroup.com/articles/icon- usability/
  10. @malekontheweb • “Years ago, we looked at how people remembered

    icons in desktop applications… In the first experiment, we changed the pictures of the icons, but kept them in the same location… • In the second experiment, we kept the original pictures, but shuffled their locations on the toolbar. To our surprise, users really struggled with this.” – Jared Spool – https://www.uie.com/brainsparks/2006/02/20/orbitz- cant-get-a-date/
