Improving the Mobile Application User Experience (UX)

Published on

If users can’t figure out how to use your mobile applications and what’s in it for them, they’re gone. Usability and UX are key factors in keeping users satisfied so understanding, measuring, testing and improving these factors are critical to the success of today’s mobile applications. However, sometimes these concepts can be confusing—not only differentiating them but also defining and understanding them. Philip Lew explores the meanings of usability and UX, discusses how they are related, and then examines their importance for today’s mobile applications. After a brief discussion of how the meanings of usability and user experience depend on the context of your product, Phil defines measurements of usability and user experience that you can use right away to quantify these subjective attributes. He crystallizes abstract definitions into concepts that can be measured, with metrics to evaluate and improve your product, and provide numerous examples to demonstrate the concepts on how to improve your mobile app.

  11. 11. Mobile Usability Challenges •  Limited attention – people often multi-tasking •  User needs triggered by context – Application needs to provide what they want at the “right” time and in a form appropriate to the current context. •  Require access to personal data, obtained either through web-based services or their personal devices. •  Require sensitivity to the task at hand, context, and requirements for personal and public data 11  ©  XBOSo@,  Inc.  2014  All  Rights  Reserved  
  12. 12. Mobile Task Considerations •  Small screen and slow interaction –  slow download speed and/or small keypads •  What functionalities of your full app need to be transferred to mobile? – More items >> less attention for each of them •  Task workflow on mobile should require just 1- 2 clicks – Each click is an opportunity for a dropped connection or slow downloading user experience. 12  ©  XBOSo@,  Inc.  2014  All  Rights  Reserved  
  13. 13. Tasks Suited For Mobile •  Tasks that have a deadline –  Buying a gift at the last minute –  Paying bills during vacations –  checking bank balances before writing a check •  Tasks that involve rapidly changing information –  Traffic, flight information, movie schedules, directions •  Tasks that require privacy –  Small screens ideal for private activities –  Check personal email or doing non-work related tasks –  Social networking 13  ©  XBOSo@,  Inc.  2014  All  Rights  Reserved  
  14. 14. Tasks Not Suited For Mobile •  Involve a large amount of complexity and/or very time consuming – Research – Large amounts of reading – Comparison of many options – Advanced transactions 14   What  is  your   mobile  app  task   and  is  it  suited   for  mobile?   ©  XBOSo@,  Inc.  2014  All  Rights  Reserved

  20. 20. Design and Test For the Task Prioritize tasks - Some tasks more important than others. –  Majority of app’s value is provided by a small number of tasks. Examples •  Highly specific –  You want to sell 20 shares of stock for a security you know you own. •  Directed, but less specific. –  Find the stocks in my account/portfolio. •  Open-ended, but restricted to a predetermined site or app. –  See where the market is today 20   If you are not involved in the design….

  25. 25. Mobile Usability Review •  Just having app/website is not enough •  What matters for users – Time to load the website – User interface – Accessibility of various functions available – What is a key function? •  Usability design needs to change, otherwise usability effect and UX will suffer 25   How  many  of  you   have  an   m.companyname .com  site?   ©  XBOSo@,  Inc.  2014  All  Rights  Reserved  
  26. 26. Mobile Usability Different Platforms Need Different Design •  Horizontal swiping now universal –  Include a visible cue when people can swipe –  Avoid swipe ambiguity: don't use the same swipe gesture to mean different things on different areas of the same screen or within same app. –  Use the same meanings for mobile phones and tablets –  Mobile-device (iPad) users typically expect to horizontally swipe while desktop websites avoid horizontal scrolling •  Mobile sites should perform better than full sites when used on a mobile device. •  Mobile apps should integrate with the desktop version 26

  84. 84. Making Assumptions •  Sense the platform and switch to a ‘mobile site’ to provide mobile users with more efficient web experience. •  Don’t make too many assumptions regarding the users’ expectations. •  For full United.com site, we need to scroll to the bottom to find the link. 84  
  85. 85. Give a Choice to Avoid Making the Wrong Assumption •  Managing user expectations of how the application should behave needs to be thought out carefully. •  Context of the user and their expectations is key. •  LinkedIn appears to be one step ahead and gives you a choice when accessing their site; an optimized mobile experience via an mobile-app, or just their ordinary website. 85  
  86. 86. Web-Mobile Integration •  Overall integration of web-apps needs to be thought out carefully with mobile scenarios in mind. •  Friend wanted to show me a product at www.costco.com. •  He sent me a link from his iPhone. I was at my desktop, and opened the link and got the mobile version. 86  
  87. 87. What Is Designed, We Test Understanding Design Leads to Better Understanding, Evaluation, and Testing OR SOMETIMES WE MUST DETERMINE THE TEST CRITERIA ©  XBOSo@,  Inc.  2014  All  Rights  Reserved   87  
  88. 88. Determine the Needs at Hand •  What need is the mobile application attempting to mobilize? •  How can the workflow be designed more efficiently to accomplish the task? •  How can the specific features and characteristics of a mobile device improve and complement the experience in contrast to the normal web-based application or other mobile platforms? 88  
  89. 89. Determine the Needs at Hand •  Implement top scenarios users want and optimizing efficiency for those scenarios ONLY. – Filling an order was a scenario optimized just for mobile. – Only 4 data items to fill in, 2 being scroll buttons, biggest button indicates precisely the task purpose. 89  
  90. 90. Mobile Usability Design Summary Points •  Quick - Can you read the text without zooming or scrolling? •  Simple Navigation-Task Oriented •  Thumb Friendly •  Visibility-Colors •  Easy to Convert/Complete the task •  Contextual •  Integrate-Seamless with webapp •  You must limit the number of features to those that matter the most for the mobile users 90   Design for the small screen. Don’t make users struggle to click tiny areas that are much smaller than their fingers. ©  XBOSo@,  Inc.  2014  All  Rights  Reserved  
  91. 91.

  92. 92. Conclusion (last one!!) Don’t Mobilize Everything •  Mobile-app versus your web-app - differentiate and discern access from each platform. •  Determine the features you really need and optimize screens for certain workflows rather than trying to do it all. •  Think about the tasks!! •  Better to have an half of an application that kicks _____ rather than a half ____ application. ©  XBOSo@,  Inc.  2014  All  Rights  Reserved   92
