There are many ways to play ultrabullet: 1. Touchscreen. 2. Mouse. 3. Graphics tablet. 4. Keyboard + mouse/tablet. 5. Brain computer interface.
In ascending order of speed:
1. Touchscreen. It’s possible to write a userscript, so that moves would be made with two fingers simultaneously. You would need to touch the piece and the destination square at once. Pros are that you can use two hands and all the fingers to move pieces.
This method seems excellent, but in practice doesn’t work as well. It takes some time to move the hands across the screen, and it’s hard to coordinate two hands in practice, because they get in each other’s way.
2. Mouse. A standard method, used by most players. Efficient, but not the most efficient.
3. Graphics tablet. Usually it’s much more accurate than a mouse and allows for a greater control and agility. It takes time to get used to though. It can take around a month of constant practice. But one would get faster eventually. An example of a good tablet is cth-480. It requires special settings as well.
4. Keyboard + mouse/tablet. By far the fastest explored method. There are two ways of using it: Let’s say you need to move your bishop from a1 to h8. a. You hover the pointer over h8 and press a key corresponding to the bishop, for example Space. b. You hover the pointer over h8 and press a key corresponding to the upper-right direction, for example 9 on the NumPad. Takes some time to get used to, but is extremely fast. May require pedals and additional keys for a more convenient use.
5. Brain computer interface (BCI). The technology is in the experimental stage, and isn’t fast enough yet. But it might become the fastest method in 10-15 years or some day in the future.
