comment Do users need 3 ways to change sound volume on their computer?
A lesson in how not to implement a master control. Do not put a mute button on a laptop keyboard that will mute all sound from a computer and cannot be reversed via the volume controls in the software. This is how my Lenovo Thinkpad works. I keep my laptop docked most of the time. One day the sound stopped working. I adjusted the software volume controls with no effect. Turns out, I had pressed the hardware mute button the night before when trying to turn off the laptop. The mute and power button are next to each other, both are round, and it was dark.

comment How can the mode of a car's transmission be made more clear?
For humor only - skip to 2:42 then listen to what he says at 2:58.

Up vote because of the last sentence.

@3nafish The Nissan solution to this problem does not rely on providing any new information to the driver. Rather than rely on the driver preventing their own skill-based error, Nissan infers the driver's intent by examining the objects around the vehicle and the vehicle's speed. Nissan does not provide more information to the driver because it will not solve the problem.

@3nafish The purpose of rephrasing the question was to point out the irrelevance of the answer to the question as a way for finding a solution to the problem. In other words, this question has no practical significance. Experts in this field have decided this question is not relevant. The solution to the problem will be found through other means.

@3nafish Ouch! A down vote on an answer that wasn't really an answer but rather a comment whose intent was to add information about a possible answer to the question. A bit harsh, IMHO.

@MattObee This is exactly what I was unaware of and improves the answer immensely. Thanks.

comment Right-Click menu awareness on Web Application
@KoenLagevenn & Charles Boyung - My experience with enterprise web applications suggests you are both wrong!!! ;) Starting around 2003 or so, participants in our usability tests of web applications started opening the context menu to search for functionality before looking anywhere else in the application. We hypothesized this behavior had less to do with (1) experience with browser context menus, or (2) overall system expertise. Rather, the applications were similar enough to desktop applications that the presence of functions in a context menu was assumed.

comment Timer for undos (aka ctrl + z for pointing devices)
Does the timer control the message indicating the availability of an Undo feature or does the timer control the availability of Undo? The Gmail example conflates the presence of the message with the availability of the function.

comment Is there any difference in element minimal sizes on 10 and 24 inch touch screens?
Voted the answer down because of this statement "Note Fitts's Law is for pointing in two dimensional space by the way; tapping is a different action. Touch occurs in three dimensional space unlike dragging a mouse. " As Alex also commented, this statement is incorrect. See this article for a description of the tasks in his first set of experiments.

comment What is the optimum button size of touch screen applications?
MIL-STD-1472G uses mm instead of px. See page 32 for a recommended 13mm x 13mm. Also, there are two dimensions to consider: button size and distance between buttons. You do not want to reduce the size of the buttons and reduce the distance between the buttons. In support of John's statement '...the 'ideal size' is really depends on the application...' notice the increased size requirement (+5mm) for situations in which the user is expected to be wearing gloves.

comment Displaying information in one dimension vs two dimensions (list vs graph)
There is no way to answer this question without more details because 'list' and 'graph' are not specific enough. There are many kinds of lists and many more kinds of graphs. Additionally, more information about the data and the user's goals would be helpful. In the absence of more details, I'd recommend starting with Cleveland's research rather than Shneiderman's.

comment How to define/classify messages and notifications
I like this question. It would be interesting to hear how existing systems fall short. Most systems I've seen (IDEs, OSs) have 3 or 4 priority levels/message types. For example: (1) you cannot work on anything until you acknowledge this message, (2) you cannot continue working on this task until you acknowledge this message, (3) you can continue working an acknowledge this message when convenient, (4) you won't see this message unless you go looking for it.

comment How to define/classify messages and notifications
Seems reasonable but I'll state the obvious...the more rows or columns you add to this table, the farther away from the goal of a 'much more simple system' you get.

comment Calendar recurrences on the last day of the month
If the task is 'recur on the last day of the month' then why not use the correct settings in Outlook rather than those shown in the question? Here is how Outlook handles this situation and it seems sufficient for the functionality implied in the question. There is no ambiguity created by the variability in the number of days in a month because 'last day of every month' means 'the last day of every month regardless of the number of days in the month.'

comment Why do physical keyboards still have built-in numpads?
At the risk of sending comments off on a tangent, I second the recommendation for using the left hand for the mouse. I started using a trackball with my left hand because of CTS. I find it works much better than using my right hand for mouse, arrow keys, and number pad.
