Elderly Users and Their Main Challenges Usability with Mobile Applications: A Systematic Review

摘要: The development of mobile applications has become a means to improve the quality life older adults since it is possible apply various sectors such as medicine, for example. Also, population aged 60 or above growing at rate about 3 percent per year. Currently, rapid ageing will occur in different parts world well, so that by 2050 all regions except Africa have nearly quarter more their populations ages and [45]. Likewise, known people require time complete tasks on devices [4] presents usability problems, generic developments do not adapt needs special characteristics. For this reason, paper addresses which are main challenges face when they interact with de user graphic interface an application how can be made acceptable target population. We summarize relevant issues three potential causes: visual, psychomotor cognitive limitations. In first category we found problems size sharpness visual elements characters, icons, images, charts buttons. use hard colors inappropriate contrast color represents significant problem seniors. On other hand, demand fast repetitive movements interaction like moving texts targets, maximization required number steps task scrollbars represent inconveniences second elderly. Finally, last category, most non-significant irrelevant graphics, non-meaningful icons decoration, animation no concise text description goes it. Besides, complex navigating through deep, expandable menu hierarchies causes persons getting lost within device menu.
