PixMo-Clocks

PixMo-Clocks is a collection of synthetic watch faces and time annotations. The data was created using facer.io. The repo supplies the meta-data needed to generate the data but does not directly contain the images

PixMo-Clocks is a part of the PixMo dataset collection and was used to train the Molmo family of models

Data Format

The data includes:

  • watchface_id: The watchface id to use to generate the image
  • watchface_name: The name of the watchface used
  • watch_time: The time the watch was set to, not all the details of the time will be visible on the watchface, so the the following two fields are needed.
  • time_format: The format of the watch, can be:
    • "No time visible": The time cannot be read at all, we still include these examples as no-answer training examples
    • "Without AM/PM": AM/PM cannot be determined
    • "With AM/PM": AM/PM can be determined (either because the watch shows military time, or shows a AM/PM indicator somehow)
  • shows_seconds: Whether seconds are shown

For convenience, this dataset includes a few fields derived from this data about what is visible on the watch:

  • hour_visible: The hour visible on the watch, between 0 and 23, -1 means not visible, 0 is 12:00am. If AM/PM cannot be determined the hour will be between 0 and 11
  • minute_visible: The minute the watch should be set to, between 0 and 59, -1 means not visible
  • second_visible: The second the watch should be set to, between -1 and 59, -1 means not visible
  • text: A text string of the time

Generating Images

Generating the image requires running a script to set the watch face to the correct time. We will include a script to generate the images as part of our code release.

Splits

The data is divided into validation and train splits. These splits are unofficial because we do not use this data for evaluation anyway. However, they reflect what was used when training the Molmo models, which were only trained on the train split.
