Why is it important to understand Fitts’ Law in such detail from a practical/industry perspective? By the time designers implement their design they don’t have control over that level of granularity
Talk about pointing innovations for accessibility +3
Include design implications that came from Fitts’ Law, like right clicking bringing the menu right next to the mouse (Savanna: I know it’s in the video, but maybe put it in the text?)
For pointing, do we always want to prioritize speed? For instance, maybe we want to make it slower to encourage users to think more before they do certain actions
Do laws like Fitts’ pigeonhole designers into certain interaction techniques since we don’t know how to evaluate things where the law cannot be applied?
How would target agnostic interactions be measured for speed, since Fitts’ can’t be applied? Talk about whether target agnostic vs target aware is better for accessibility +1
Define Fitts’ Law and an example before diving into the components +2
Chapter assumes speed is the only important value for pointing for the majority of the chapter without going over other values like comfort
Talk about how Fitts’ Law would change if we were to use eye movement instead of hand movement, for example
Why haven’t things like LightRing become more widely adopted?
Talk about pointing and Fitts’ law for non-screen based interfaces, like AR/VR, or TV remote control +5
Talk about the importance of the visual feedback in pointing and how not having this in a VUI can make it harder to point with a VUI
Chapter is dense and difficult to digest
Talk about Fitts’ in tension with design strategies. For instance, big buttons are good for Fitts’ but could lead to cognitive overload, etc.
More examples of pointing technologies for those with limited mobility +1
Mention Swipe, the way of typing on a keyboard using one motion
More examples of direct vs indirect pointing? Also, introduce these earlier in the chapter, before Fitts’ +1
Fitts’ law doesn’t seem to apply to every kind of pointing, such as VUIs (in regards to “it applies to any kind of pointing”)
Fitts’ law diagram should have the A distance to be the edge of the circle, not the center
For the Fitts’ law explanation, make it so the reader doesn’t have to keep scrolling up to the image to see the equation with the explanation
“Fitts’ law itself actually strongly implies a speed accuracy tradeoff”--how is this possible if Fitts’ doesn’t take error into account? +1 (Savanna: seems like more context/explanation about this study would be useful)
Is there a common place users leave the mouse when idling the computer?
Are CTA buttons placed so that the mouse can get there faster (not just for visual hierarchy)?
Are there any other important laws about pointing in user interfaces?
Talk about the future of pointing
Why is Fitts’ still the main equation used when we have things like zooming and snapping and other advances to pointing?
How was the size of the cursor decided upon, with respect to it being easy to point to a target?
What would actual values of Fitts’ look like and what’s a good vs a bad value?
Grammar/typos:
“person’s baseline motor abilities and the the design of a device rhather than the difficulty of a particular pointing task.”
“These types of pointing “errors” are just as important isas movement time”
