Braille screen input is very Laggy

Hi. I'm starting to find that braille screen input has become increasingly Laghi since the beginning of iOS 18. I'm running an iPhone 16 that iOS 18.4.1 and all apps and firmware are up-to-date. Is it just me? The other thing to note is I do have a screen protector on my phone that is tempered glass. Would this make a difference? I've always had one on and have noticed a difference even so.

Hi Kerry . I have a few ideas. Sorry if you have already thought of them. Maybe change the screen protector if you can, or remove it temporarily to see if that helps? I haven't seen this issue for a while and didn't notice any changes with IOS18.

One thing that has sometimes helped in the past for me when things have got laggy, is to change the Braille translation table setting away from whatever you are using to something different, do a bit of braille and see if you notice any difference and you can then change the translation table back to whatever you were using before. For example, you could change from UEB to American Braille, or vice versa, and then change it back again. I have found that doing this seems to reset something and make it work a bit better. The lagging I experienced involved space characters not being inserted even where I was sure I had done the correct gesture, so phrases and sentences would just end up as one long word and I would have to manually re-insert spaces.

I am sure you have already tried this, but remember to calibrate your braille dot positions regularly by pressing dots 4-5-6 and then dots 1-2-3 quickly afterwards, within about a quarter of a second.

I hope some of these ideas help a bit.

Good luck

The thing I find irritating is that BSI will often get the dot positions wrong despite my seemingly only recently having got them right, but worse, when you press 4-5-6 then 1-2-3 to recalibrate the dots, the time during which it's laboriously saying "Dot positions calibrated" is time you lose while Brailling input, instead of hearing what you're writing.

Yes I know it's a little thing, but it does somewhat make me resent the suggestion of the much-improved iOS 18 BSI. I mean, when was the last time you actually used Command Mode? Next to that, this little irritation is a massive change. I got used to the limitations of iOS 17, but of the newly added features, the automatic activation interferes with password fields so you can't really use it, and the special command for entering and exiting means you can avoid the rotor, all right, but must remember to exit because otherwise you might delete characters when you think you're reviewing text for editing. It seems that even marquee accessibility triumphs have caveats.

Grumble, grumble, etc.

To me BSI is very laggy when I use Liblouis Braille tables.
I use Liblouis for Hebrew and English for Input and Output.
I use my Braille Display but it's not with me wen I driving on the buss.
