markpenders 8:59 Location: Phone Model: | Hi, I noticed the following while playing around with v0.6.4. When I pause the track (and have the "show averaged location while paused" box ticked, I would expect that, since the location displayed is the averaged location, the speed displayed will slowly average down to 0. But it seems TMJ keeps on displaying the speed according to the "normal" jumpy GPS-behaviour around a fixed position (just as the bearing does). What are your thoughts about this? Cheers, Mark | |
Stephen 14:27 Location: Phone Model: | Hi Mark, Hmmm, thats a point, though I'm not quite sure which behaviour makes most sense. As you say, currently it just continues displaying the speed/bearing from the non-averaged data. If it was to instead display the speed/bearing of the averaged location, this would better match the motion of the cross on screen, but then wouldn't bear any relation to your actual movement on the ground. Perhaps it would be better if the speed and bearing were just completely hidden whilst the track is paused. That would possibly be less confusing, do you think? Cheers, Stephen | |
markpenders 16:21 Location: Phone Model: | Hi Stephen, Correct me if I'm wrong, but I thought the averaged position was introduced for geocache purposes (i.e. to accurately pinpoint a certain position). My line of reasoning was: when the track is paused to obtain this location, the position received from the GPS is replaced by a calculated position based on the averaging algorithm. If the speed is calculated from the difference in position, then it should tend to zero. If TMJ continues to take the speed from the GPS, then you have two sources of information (averaging algorithm and the GPS) that do not correspond with eachother. Displaying no speed and bearing ... hmm: for bearing I go along, but it would give me a sort of comfort feeling seeing the speed tend to zero, sort of as a reassurance that my readout is becoming more accurate. Does this make any sense? Cheers, Mark. | |
Stephen 17:25 Location: Phone Model: | Yeah, maybe...! I'll do a bit of testing with the speed, see how well it works... | |
