Who did the research?
The independent, quantitative study was conducted by Radius Research in multiple U.S. markets.
What flat panel was used?
Sony 4k Ultra HD model - #1 selling 70-inch flat panel (Based on USA market share data)
How many students were tested?
106 students ages 12-22. Radius determined the sample size needed for this study.
How big was the room, and how far away were the students?
The room was about 30'x30', and there were 30 seats in a traditional classroom layout (5 rows, 6 seats/row). The first row started about 8' from the display, and the back of the last row was about 27' from the display.
What was shown to them and how big was the text?
Students were shown basic content - a simple text table, Excel spreadsheet and PowerPoint schematic - then asked to find data (a word, short phrase, or number) and copy it down. Size of text varied from large headlines to smaller details.
Which seats were the worst?
The sample size for each eat is not large enough to substantiate "can't read" statement for a particular location or distance, but the error rate of respondents in the back rows was significantly higher than in the front rows.
How was the eye sight of participants checked?
Participants were asked about their eyesight and if they were using glasses/contacts they had to wear them during the study.
