What Is UX?• I study how people interact with technology
• Websites, apps, video games, physical objects
• I make these products more user friendly by:
• Taking a user centered approach to design and research
• Conducting usability tests with specific tasks
• Then getting awesome feedback (data) about the product
• Give this data back to the developers and designers to take into consideration with future iterations

Research Question
Is there a difference in a person’s reading speed and
comprehension on various screen sized devices?

Why We Did This• Technology is always changing
• Devices made just for reading (Kindle)
• Screen sizes are getting bigger
• Screen resolution is getting better
• Books seem to be becoming obsolete

Method To Our Madness• Users were recruited from Psychology classes
• They were given a demographic
• What devices they use and how often
• If they liked to read and how often
• Do they have a reading disability?
• Next we gave them the Nelson Denny

Nelson Denny• Standardized measure of reading performance
• Participants had 15 minutes to work though 7 short passages
• Each passage has its own set of questions
• With a total of 38 comprehension questions.
• We were able to get an idea of their reading speed and comprehension

Method To Our Awesomeness• Each participant read a short story on each device
• Used 3 devices which had Amazon’s Kindle app
• Default font was Caecilia
• 17” Desktop computer
• 10” Kindle
• 3” Smart phone
• The participants were given 10 min to read the stories

Passage from The Dubliners
There was no hope for him this time: it was the third stroke. Night after night I had passed the house (it was vacation time) and studied the lighted square of window: and night after night I had found it lighted in the same way, faintly and evenly.

So They Read, Now What?• We wrote down the last 4 words that they read
• So we could calculate words per minute
• Participants answered 2 questions for each story
• Calculate comprehension
• Fill out satisfaction survey for each device
• Then they read the next story on the next device
• Rinse and repeat until done with stories

Question Why Method Results Real World
• Blink was easier to read than Dubliners
• Dubliners is an older book (1914)
• Has a lot of infrequently used words or metaphors
• No significant difference between screen size and reading speed
• Over 70 participants experienced no appreciable difference between their reading speed or their comprehension when their reading was compared across the four screens
• Didn’t seem to matter if only a few sentences were presented on the 3” screen or if several paragraphs were presented on the 17” screen

• Basically this means that people are able to switch from small screens to bigger screens with ease
• Reading speed did vary a lot though
• Some participants were as low as 50 wpm
• Others were as high as 300+ wpm
• Range of 250+ wpm (we call these people outliers)
• Average reading speed for our participants is 174 wpm
• Most adult’s reading speed is 200 wpm

Question Why Method Results Real World
• Reading disabled participants said that they enjoyed using the smaller screened devices
• Comprehension has floor and ceiling effects
• When given multiple choice questions, users got them all correct
• When given open ended questions, it was difficult to justify what was correct or incorrect

Other Factors• Difficulty of the reading material will alter reading speed and
comprehension
• Participants may not be in the right mind set
• They could get bored, worry about a test, not have enough sleep
• Some participants forgot the exact place they stopped in a story
• This alters our calculation for words per minute

Real World Uses• If you're making an app with blogs or news articles
• Make it for tablet first
• Don’t worry about screen size
• Make sure the content fits on the screen (responsive)
• Use conversational language
