# Presentor
|
||||
Use your Bangle to present!
|
||||
This app basically turns your BangleJS watch into a presentor tool.
|
||||
Very useful for presentations or when you are teaching a lesson.
|
||||
|
||||
### Features:
|
||||
+ Control your (powerpoint) slides by swiping left and right.
|
||||
+ See pre-programmed presentation notes by swiping up and down.
|
||||
+ See if you are on time in your presentation.
|
||||
+ Get notified if you go over-time for a certain subject.
|
||||
+ Control cursor or spotlight in mouse mode (pressing the button).
|
||||
|
||||
### Usage:
|
||||
Here is a step by step guide (thanks mu1)
|
||||
1. If bluetooth connected to PC/laptop (check in bluetooth settings):
|
||||
Select Bangle.js > Remove Device
|
||||
|
||||
2. On your smartphone, in "Gadgetbridge", close connection by long-pressing "Bangle.js"
|
||||
|
||||
3. Open banglejs.com/apps and select "Connect" (right upper corner)
|
||||
|
||||
4. Select Bangle.js in blue bar in pop-up window and select "Connect"
|
||||
|
||||
5. Search "Presentor" app and select diskette icon
|
||||
|
||||
6. Select "Clear" to start making new notes.
|
||||
|
||||
7. Fill the subjects, times in minutes (seconds optional) and Notes (optional)
|
||||
The subject/times are on your watch displayed in a tall font, the notes in a very small font
|
||||
Note: If you don't fill in any notes you can still save and the presentor will be for input only and not give any timing details.
|
||||
|
||||
8. Select "Save" and exit the pop-up window
|
||||
|
||||
9. Select "Disconnect" (right upper corner)
|
||||
|
||||
10. Open the Presentor app. This will start the correct HID service as well.
|
||||
|
||||
11. Open "Bluetooth & other devices" screen on PC/laptop and select "+" to add a device
|
||||
|
||||
12. Select "Bluetooth" and select Bangle.js
|
||||
If "Try connecting your device again." is shown, switch PC/laptop bluetooth off and on again
|
||||
|
||||
13. Start your presentation.
|
||||
- Swipe up to start timer for first subject
|
||||
- Swipe down to pause
|
||||
- Push button to switch between mouse mode and timer/presentation mode
|
||||
|
||||
14. Timer function
|
||||
- Next subject: Swipe up
|
||||
- Previous subject: Swipe down
|
||||
- Pause timer: Swipe down to begin
|
||||
|
||||
15. Presentation function
|
||||
- Next presentation slide: Swipe right or just touch
|
||||
- Previous presentation slide: Swipe left
|
||||
|
||||
16. Mouse mode
|
||||
- Swipe to move pointer over the presentation screen
|
||||
- Tap to left click.
|
||||
- Hold longer to right click.
|
||||
|
||||
17. Holding mode
|
||||
In timer/presentation mode, hold one finger on your Bangle screen, point your arm foreward
|
||||
- Mouse up/down on screen: Tilt your hand up/down
|
||||
- Mouse left/right on screen: Rotate your hand counterclockwise/clockwise
|
||||
|
||||
18. Spotlight mode
|
||||
- Dubble press button to go into presentor mode.
|
||||
- Allows to move mouse but no clicking.
|
||||
- Presses SHIFT+F10 on start (you can use app such as powertoys to set spotlight to this combo)
|
||||
- Presses F10 at the end (will dis-engage spotlight for instance in powertoys)
|
||||
|
||||
19. End of presentation?
|
||||
Switch bluetooth PC/laptop off or see step 1
|
||||
|
||||
20. Re-activate smartphone bluetooth (incl. Gadgetbridge)
