This is a specification covering settings, notifications, and other UI for mice and touchpads (sometimes called trackpads).
Prompting to set up a mouse or touchpad
Whenever no pointing device is detected, the “Mouse & Touchpad” screen of System Settings should open with the text “No mouse or touchpad detected”. The following text should depend on the situation.
- On a pocket PC: “You need to use a Bluetooth mouse or touchpad with this display. Make sure it is close to the phone and its batteries are charged.”
- On a PC: “Connect a mouse or touchpad via USB, or use a Bluetooth device. If a Bluetooth device isn’t detected, make sure it is turned on and its batteries are charged.”
As long as the screen is open, Bluetooth should be turned on to detect a Bluetooth keyboard. If it was off previously, it should turn off again if you exit the screen without connecting a device.
Ubuntu should open the “Mouse & Touchpad” screen of System Settings, to display this prompt, if all of these are true:
- you are using a PC, or a pocket PC with a non-touch external display in use;
- no pointing device has been detected;
a keyboard has been detected (so Ubuntu is not prompting you to connect a keyboard instead);
- System Settings is not already the active app;
System Settings “Bluetooth” or “Mouse & Touchpad” screen is not already open.
“Mouse & Touchpad” settings
In both “Mouse” and “Touchpad” settings:
- The double-click test face should initially have eyes closed. 😴 Single-clicking on it should keep its eyes closed, but for two seconds its expression should alter, 😌 and the text “Not fast enough” should appear alongside. Double-clicking on it should should, for two seconds, open its eyes 😀 and display text “Double-clicked” alongside.
- “Primary button” should be present only if the number of buttons is two or more or unknown.
In the “Touchpad” settings:
- “Tap to click” should be present only if the touchpad has a tappable pad.
- “Scroll with two fingers” should be present only if the touchpad allows this.
TBD: Add scroll direction as a common setting.
TBD: Split Mouse vs. Touchpad settings to separate screens on the phone.
