We've noticed some useful strategies that'll help you make the most of your experience while using Tuva on the iPad. We recommend the following:
- Orientation: Orient your iPad in landscape mode. Ensure your iPad's rotation setting is unlocked.
- Web Browser: To use Tuva, you may use the Safari app that comes pre-installed on the iPad. Or, you may use the Chrome app, which can be downloaded from the Apple app store.
- Viewing the Graph with the Keyboard: While the iPad keyboard is open, the viewing area will shift to accommodate the keyboard. This makes it difficult to view the plot and also type with the keyboard at the same time. If you need to view the plot, we recommend closing the keyboard, then you may view the plot, and then re-open the keyboard by clicking in the text area you want to type in.
- Keyboard: When going through an activity on Tuva, you're going to come across different types of question: multiple choice, multiple selection, and open-ended. Typically, it's fine to hold the iPad with one hand and answer the multiple choice and multiple selection with the other hand. However, when it comes to open-ended questions, it helps to place the iPad on your lap or on a desk to fully utilize both hands as you type multiple sentences into the text area.
- Dragging Attributes: To drag an attribute from the case card to one of the axes or legend, click and hold an attribute for about half a second before beginning to drag.
- Dropping Attributes on the Legend or Axis: To drop an attribute on the legend or on the X or Y axis, drag the attribute you've selected over to the drop area. Make sure your finger is over the drop area before releasing your finger from the screen.
There are a few issues that are queued to be fixed:
- Double tapping any part of the screen will zoom in and magnify the screen resulting in a difficult experience trying to zoom out. Double tapping will eventually be disabled on the Tuva data exploration tool as it's not necessary for data manipulation.
Issues In Progress
These are the issues we're currently working on:
- The About the Dataset pop-up will scroll when it first loads, but will fail to scroll after closing it and re-opening it.
These are the issues we've fixed:
- We fixed an issue while drawing annotations in the plotting area not responding to touch inputs on the screen. This includes drawing with the pencil, drawing rectangles, circles, arrows, or adding and manipulating text annotations.
- We fixed an issue with the case card not always scrolling. Previously, attributes were sometimes picked up and dragged instead of allowing someone to scroll through a long list of attributes. We've implemented new logic that will detect if you're scrolling through the case or if you're attempting to drag and drop an attribute from the case card to one of the axes or the legend.
- We've increased the click area for the Swap Axis button and the 'X' button that appears on the axis to remove an attribute.
- We've increased the drop areas for the X-axis and Y-axis to make it easier to place a finger over it and drop an attribute. Previously, the drop areas were too small to be user friendly on a tablet.
- We've implemented a hover state that will highlight the axis or legend if an attribute is over it. This provides visual feedback to let you know you're currently holding an attribute over one of the drop areas.
