Class SAKStats

java.lang.Object

SAKStats

public class SAKStats
extends java.lang.Object

SAKStats - a program to provide stats and other services related to the scanning ambiguous keyboard (SAK) implemented in OneKey.java.

Invocation:

     PROMPT>java SAKStats file letters [-olps|-mlps|-mlpk|-ow] [-wfk|-wfks|-spc|-sps]

     where  file = word-freq dictionary file
            letters = letter-key assignment (e.g., abcdefg-hijklmn-opqrstu-vwxyz)
            -olps = one-letter-per-scan method
            -mlps = multiple-letter-per-scan method
            -mlpk = multiple-letter-per-key method
            -ow   = optimized-word method
            -wfk  = output word-freq-keycode data
            -wfks = output word-freq-keycode-scan data
            -spc  = output scans per character stat
            -sps  = output selections per scan stat
 

Note: "mlps", above, means multiple letter selections during a single scan through the letter-selection region. "mlpk" means multiple letter selections during a single scan step interval where multiple desired letters are on the same key.

Here are some sample runs:

     PROMPT>java SAKStats d1phrases2-wordfreq.txt abcdefgh-ijklmnop-qrstuvwxyz -ow -spc
     abcdefgh-ijklmnop-qrstuvwxyz ow 1.7131456157916434

     PROMPT>java SAKStats d1phrases2.txt abcdefgh-ijklmnop-qrstuvwxyz -ow -sps
     abcdefgh-ijklmnop-qrstuvwxyz ow 0.603138251036028
 

Here are a few runs generating word-freq-keycode-scan data:

     PROMPT>java SAKStats d1phrases2-wordfreq.txt abcdefghijklm-nopqrstuvwxyz -wfks -ow > onekey-k2ks-scans.txt
     PROMPT>java SAKStats d1phrases2-wordfreq.txt abcdefgh-ijklmnop-qrstuvwxyz -wfks -ow > onekey-k3ks-scans.txt
     PROMPT>java SAKStats d1phrases2-wordfreq.txt abcdefgh-ijklm-nopqr-stuvwxyz -wfks -ow > onekey-k4ks-scans.txt
     PROMPT>java SAKStats d1phrases2-wordfreq.txt abcdefgh-ijklm-nopqr-stu-vwxyz -wfks -ow > onekey-k5ks-scans.txt
     PROMPT>java SAKStats d1phrases2-wordfreq.txt abcdefgh-ijkl-mno-pqr-stu-vwxyz -wfks -ow > onekey-k6ks-scans.txt
