Tips for Typing with BrailleTouch
The following are some hopefully helpful tips with using the BrailleTouch app released on January 31, 2013.
I have tested holding the iPhone using a Case-Mate Phantom case with my iPhone 4s, using a slider case, and without a case. All of these tests were performed with and without using headphones.
The app was equally usable for me utilizing all of these methods. Be aware, however, that using it without headphones and with a slider case and without a case entirely tended to block the speaker, so it might be advisable to use headphones when in a crowded and/or noisy environment. For some reason, I did not have this issue when using the Case-Mate Phantom case. In one point, however, I must disagree with the BrailleTouch User Guide, as it states that if using headphones, it is better to use those with a 90-degree plug. I found it easier to use headphones with a plug that goes straight in and not one with the right angle on the plug.
All of this is just a precursor to telling you what you really want to know; what is the best way to hold your hands while using the device!
When using BrailleTouch, remember to have your phone in your hands so that the home button is oriented to your right. The Screen Lock button should be on your left-hand side, and the screen of the phone should be facing either completely away from you or, my preference, face up in your hands with the back of the phone/case parallel to the ground.
Now I have found the easiest method for successfully typing with consistency is to rest the part of the phone with the lock button positioned in the webbing between my thumb and forefinger, while the bottom of the phone nearest the home button is positioned against my right palm. I also find it easier to type with my elbows tucked in nearer my body rather than pointed outwards.
Again, the best advice I can give is to play with BrailleTouch and find the position that seems most comfortable to you. If it helps, think of BrailleTouch as a braille machine with an ergonomic keyboard. I hope this has been helpful to at least some people that might be struggling with getting a comfortable grip and with getting consistent writing with BrailleTouch. If you have any questions, please do not hesitate to leave me a message. Good luck and happy brailling.
