<br>
Since I was recently working again more with RKWard (analysing usability<br>
data…), here are some usability problems I found. I tired to estimate<br>
how hard they are to fix, so one could focus on the most effective fixes.<br>
<br>
I split them in different mails, so that the issues stay separated.<br>
<br>
1) Reading CSV Data<br>
===========<br>
<br>
First row as col names (easy/medium difficulty fix)<br>
--------------------------------------------------------------<br>
<br>
It took me a long time until I found how to get the first row as column<br>
name. Assumed reason: The checkbox for the option (nicely put on the<br>
first tab!) is somewhat squeezed between other elements. On Linux it<br>
looks like it is part of "quick options", on Mac this impression is even<br>
more extreme, since it resides in some darker-colored box.<br>
<br>
Violated Heuristics: Usability, Standards (all other options have some<br>
sort of headline)<br>
<br>
Proposed Fix: Give it a space on its own (an own line) and/or a headline<br>
<br>
<br>
Aside there are several smaller issues I found.<br>
<br>
Wordings (Easy fix)<br>
--------------------------<br>
<br>
a) In "Column names in first row" (1st tab) it is unclear if the first<br>
row is the CSV’s or the resulting data.frame. (Suggestion: "Use first<br>
line as column names" (?))<br>
b) "Default": On the second tab there are many "Defaults", but it is<br>
unclear what this default is.<br>
c) "Edit Object" (1st tab, save to options): This seems to open the<br>
object after import in the table view, but it suggests it somehow<br>
directly changes some object (like a mixin or an overwrite...)<br>
(Suggestion: "Open after Import" or "View after import")<br>
<br>
Active/Inactive Fields (Medium)<br>
-----------------------------------------<br>
<br>
Depended on other fields, some radiobutton options are active or<br>
inactive. Sometimes it is hard to follow why, and the many inactive<br>
options irritate<br>
Possible fix: Using Dropdowns (?) like in RStudio’s import<br>
<br>
Preview (Difficult)<br>
-----------------------<br>
This is probably hard to implement but a preview of the first 5 or so<br>
imported lines would be great (also RStudio inspired)<br>
<br>
Flow: Call the file selector (easy to medium)<br>
----------------------------------------------------------<br>
Before any option makes any sense, I file needs to be loaded. So<br>
flow-wise it would make sense to open the file picker right away. It<br>
also would match user expectations, since it is standard in many other<br>
applications.<br>
<br>
<br>
<br>
<br>
Kind Regards,<br>
Jan<br>
