Dataset files overview
The dataset include the following files:
-
A comma-separated file matching each UI identifier with one of the 20 design topics. Link to file
screen_id,topic 50245,tutorial . . .
-
Screenshot images, in JPG format at 540x960 px resolution. Link to sample file ~ Download ZIP file (110 MB, 157 MB uncompressed)
-
Semantic wireframe images, in PNG format at 540x960 px resolution. Link to sample file ~ Download ZIP file (5.3 MB, 10 MB uncompressed)
-
Semantic annotations, in JSON format, with all the UI components, text buttons, and icons encoded in the wireframes.
-
View hierarchies, or DOM-like tree structure, in JSON format. Link to sample file ~ Download ZIP file (1.7 MB, 16 MB uncompressed)
{ "class": "com.android.internal.policy.PhoneWindow$DecorView", "bounds": ...
-
App metadata, in JSON format. Scrapped from Google Play as of August 2020. Link to sample file ~ Download ZIP file (2.8 MB, 8 MB uncompressed)
{ "title": "Sync.ME - Caller ID, Spam Call Blocker & Contacts", "icon": ...
Note: There are 296 UIs with empty metadata, since by the time we scrapped Google Play they were no longer available.
Other files
You can download additional files from the Rico dataset such as UI layout vectors (8 MB), interaction traces (6 GB), and animations (214 GB). Enrico uses the same screen IDs (UI identifiers), so you can easily match the files in Rico.
Issues
Thanks to Samuel Rosas from Aalto University, we have identified a few issues in the dataset that you should be aware of. Please see issues.csv file. We have categorized the issues into three sources of errors (screenshot, wireframe, and hierarchy) and have included a description of the issue and a degree of severity (low, medium, high). Here's the number of UIs affected:
severity
source low medium high total
---------------------------------
screenshot 0 8 2 10
wireframe 16 9 14 39
hierarchy 32 0 0 32
---------------------------------
total 48 17 16 81
We have decided not to remove any of the affected UIs because these issues may or may not impact your study.
For example, if your model or analysis doesn't rely on the view hierarchies,
then you can ignore the issues that are flagged as "hierarchy" in the source
column of issues.csv
