First, thanks to those who came to my project presentation.
Here you can find some resources that I used in the presentation -
Some of the questions asked during the presentation were about whether my PSALM program could be used during a service. I would like to stress here that although it could be, only the main screen is designed for this - so the editors + song recommender are intended for use in preparing for a service. They could be adapted for use though, but because usually the lead worshipper (person leading the band) has their hands full with an instrument, it would be difficult to use any program. In my 'further work' section of the presentation I didnt have time to talk about input methods. It would be great to use a system similar to worshipsession, which uses a foot pedal to control just two functions - for example, 'display next song' & 'display previous song'.
The problem with using PSALM mid-service only shares the same inherent problems with songbooks though, in that fiddling around trying to find the next song to play can be frustrating. I believe that PSALM is at least as good, if not better than songbooks though in that searching is much quicker and the thematic search especially makes this job easier.
As to the issue of depending on (any) computer programs to aid running a church service/worship 'set', it is important to see PSALM as a songbook replacement and not more than it actually is. Lead worshippers should not, and generally don't, rely on their songbooks to decide the order of service, so musn't then do it with PSALM either! (Which may explain why I haven't designed PSALM's song recommender to be easy to use mid-service).
