Factoring to Expose Interactions
Stylus and mouse outperformed trackball (hypothesized)
Stylus and mouse the same (not hypothesized)
Initially, effect of input device did not interact with menu type
- this is when comparing globally
- BUT ...
More detailed analysis:
- Compare both by menu type and device type
- Stylus significantly faster with Marking group
- Trackball significantly slower with Exposed group
- Not hypothesized!
