26. Slide button test
A. Purpose
This is for testing the slide button sensor. Check the slide button recognizes the finger correctly.
B. Behavior
[Description of the algorithm]
Without the clicking the button, the touch type camera can be operated by touching the button.
This type camera operates by push (when the finger is on the button) and release (when the finger is off the button)
signals.
To test the Push and Release signals, test all of the buttons.
Testing the 13 buttons will take long time. To reduce the testing time, make a condition.
The condition is :
Slide the finger across the buttons and the menus display. And then slide the finger across the button again, the
menus disappear. .
But, there are some problems when testing the buttons.
[Exceptions of the test]
※ When the finger is on / off the buttons, Push / Release signals will generate. But, if the finger is not off the button
but moves to the next button, the Release signal doesnn
’
t generate. The Release signal is generated when the
finger is off the button.This means, the camera controls functions with the Push signal and the Release signal is
generated when the finger is off from the last slide button. So, in this test, we are checking the Push signal only.
①
Put the finger on the button and move the finger with checking the icon.
②
If the previous icons are disappeared in order, the Push signal is generated correctly.
③ If the icon is not disappeared, though the finger is on the button correctly, that has defect.
④ Slide the finger across the buttons again, and the icons will display.
