TLDR
It shows how blind users think, act and perceive in performing common social media functions non-visually, and has implications for the design of non-visual user interfaces to access social media through ‘Internet of Things’ and in multi-tasking situations.Abstract:
Social media allow people to communicate, collaborate and socialize for personal and professional matters. However, their sight-centered design can present access and usability problems for the blind. Existing quantitative approaches to usability testing do not provide in-depth assessment of the problem. This paper presents a qualitative approach to test social media usability, and illustrates its application to evaluate Facebook for the blind. Think-aloud observation of six blind participants generated verbal evidence of their Facebook interaction experiences. Verbal protocol analysis explained the nature of interaction challenges in performing common Facebook functions. Design standards analysis explained design errors in Facebook interface. It helped identify remedial measures to potentially improve Facebook usability. Findings demonstrate the utility of the qualitative approach to feasibly evaluate social media usability for blind users. It shows how blind users think, act and perceive in performing common social media functions non-visually. This has implications for the design of non-visual user interfaces to access social media through ‘Internet of Things’ and in multi-tasking situations.read more

A mathematical model of the finding of usability problems
Jakob Nielsen,Thomas K. Landauer +1 more
TL;DR: It is found that the detection of usability problems as a function of number of users tested or heuristic evaluators employed is well modeled as a Poisson process, which can be used to plan the amount of evaluation required to achieve desired levels of thoroughness or benefits.
