Determining Optimal Permutations for Rows The most frequently read characters are to be placed in the middle row for fast access, followed by the top row, then the bottom. Let’s start by grouping all 26 characters into these rows. The letters on modern keyboards make up three rows: the home (middle), top, and bottom rows. This is easily achieved by traversing the text (cleared of non-alphabetical characters) and updating the Markov Chain at every iteration. A Markov Chain, in this case, is a statistical model that maps each character to the frequency of each character that follows it. Our keyboard models need to understand how characters relate to each other in various contexts. Pride and Prejudice, Jane Austen (13k lines) However little known the feelings or views of such a man may be on his first entering a neighbourhood, this truth is so well fixed in the minds of the surrounding families, that he is considered the rightful property of some one or other of their daughters. sample.txt It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife. The method we are using extracts language from a text file.
The number, function, and special character keys are not to be repositioned.Hitting keys on the home row is always faster than the top row, and the top row is always faster than the bottom row.To accomplish this task in a reasonable timeframe, let's follow these assumptions: I, for one, do not have infinite computing power. To find the one, true best keyboard layout, one must use brute force: testing every permutation of keys for typing efficiency. More on this later! Necessary Assumptions More generally, this task can be applied to any language or collection of words. Because QWERTY was developed in the 1870’s, I challenged myself to use modern computer science to generate a more optimal keyboard. , the ubiquitous QWERTY keyboard is assumed to be the optimal layout for typing in the English language. # window = (wid, Window(wm=self, wid=wid, mapped=True)) ("ButtonRelease", self.on_mouse_event)ĭef on_property_notify(self, evname, xcb_event):Ītom = _name(xcb_event.atom) ("ConfigureRequest", self.on_configure_window) ("DestroyNotify", self.on_window_destroy) ("ClientMessage", self.on_client_message) ("PropertyNotify", self.on_property_notify) # ("CreateNotify", self.on_window_create) Self._eventloop.add_reader(fd, self._xpoll) #DebugHelper.draw_borders(, obj2)ĭef _init_(self, display=None, desktops=None, loop=None): If Keyboard.is_down(pygame.K_LCTRL) and Keyboard.is_down(pygame.K_s) :įor gameObject in () :
