These Humans...
How do people act? How should we develop strategies to get them to maneuver through our website and stay (possibly to sell them things or to continue to use our products)? First, how do they select something?
What about their attention levels, how do we get their attention?
- Color
- Sound
- Boundaries
- Moving/Flashing items
So how do we know?
Assume you have a website and you what to know whether or not it is "good". Some options are available to us to try to figure this out:
- Number of Visits / Traffic
- Length of stay on the site (harder to calculate)
- Geographic Distance between users
- User participation / comments
- Surveys
- Actual sales
- User Testing and Evaluation
Case Study - Netflix
Lets consider Netflix:
- Goal - signup new users before they leave the front page
- Front Page - family on a couch
- Question - Who has the remote?
Consider that Netflix costs (based on 2012 numbers)
- $1.00 per movie sent by mail
- $0.05 per movie streamed online
How can Netflix encourage straming movies instead of sending by mail, just using HCI?
Where do users look?
Eye trackers have been used in multiple web-site design studies. In general, users will view:
- Top Left of the web-page first
- Big text with whitespace around it
- Human faces attract the eyes
Points on Quality
It is extremely important to have consistency throughout your pages and a method with which you navigate through them. Addition points:
- Be careful when choosing the text for linking
- If you change one color, change them all
- Sometimes the most emphasized things get ignored
- Put dates on your pages
- Don't let the interface dominate the content
- Minimize heavy borders
- Use background images with great caution
