I'm developing Timer camera app(IOS).
Generally , this app let set the timer to any number of seconds you want, when the time reaches 0 theres shutter sound and the image saves.
What i am trying to understand : What is the best indicator to use(Sound,Visual Effect,Flash etc) in order to notify the user to the up-coming shoot.
Example : Users choosing between Back\Front(Selfie) camera position , Sets the time(5 sec for example),Click on the "capture" button. Timer running from 5 to 0 , than the shoot is taken
Additional Info :
Because the users can see the Screen in Front(Selfie) Position im using visual indicator to let him know when the image is taken.
My Concerns :
When using the Back Position My only options to notify the users(He cant see the screen) are:
1)Flash - I'm preferring not to use this at all , i think its to much attention taker(some people might don't want use it, very dominant)
2)Sound - My preferred solution.
1) What is the sound type I should use? - for example : Beep,Background sound,White sound,please sound etc
2)The million dollar question , in which way/sequence/logic/frequency you think i should "present" it to maximise the UX? , in terms of not embarrassing/noisy etc
I hope we can figure this one - Thanks! :)
