[Xerte] Text Entry Hints

[Julian Tenney]

The problem will be gaining some agreement on an algorithm, and I'd
rather get something working whilst it's still the 21st century...

 

There are some glitches - because of this line:

 

newHint += Math.random() < 0.7 ? '_' : ans.substr(i,1);

 

it is possible that the hint is empty - or that it shows all of the
letters. Neither is desirable, so I need a better way of picking the
letters at random. Perhaps following some rules like:

 

-          First hint: letters = Math.floor(wordLength / 4); //i.e.
about a quarter of the word's letters are shown in the hint

-          Second hint, add another quarter of the letters

-          Third hint - add another quarter of the letters.

-          No more hints - and if you keep typing the hint disappears
and you don't see it again.

Glitch in the eval routine maybe?
In the second entry started to correctly type repair, but got hinted at
"e".

I think it is a much more engaging way to handle it.
AFA the algorithm goes, I'd be tempted to throw it in the lap of a
language development type. I'd figure there is some culturally dependent
pattern of word formation/recognition that might come into play and have
a set of rules.
e.g. Show consonants first? Vowels? Final letter?

Seeing this is multi-language, it would also be interesting to see if
there were variations in the above between languages.

Reminds me of the "What do you see?" experiment where they took a
painting of a bull and obscured it with paint spackle.
Very few north americans/europeans could identify it, but as they moved
closer to the Mediterranean, the recognition rate started to rise.

But my favourite experiment is still Stanley Milgram's.

Interesting problem: how to generate the hints:

 

For example, the word is 'interactive', so generate successive hints
like this:

 

_n___ac__v_

Int__act_v_

Int_ractiv_

 

Where successive hints become more helpful, building on previous hints -
or do we show a new random hint each time, i.e.

 

_nt_ra_ti_e

I_t_r_ct_ve

In__ra__ive

 

So what are the rules?

 

-          Need to wait for at least so many characters to be typed -
fixed or related to the length of the word - wait for more characters to
be typed before hinting longer words?

-          Only show so many hints per word - but short words should get
less hints than long words;

-          Only show a new hint once more characters were typed than the
last time we showed a hint - one more? Or several? Is this related to
the length of the word?

-          Build the hint replacing characters in the answer at random
with underscores? Or always add n new helpful characters to the hint? Is
n related to the length of the word?

-          Should the first character always be included in the hint?

 

Give it a whirl with a few words of different lengths and you'll see it
isn't so straightforward...

>The handsets also have a silly little game you can play  standalone
that works like that.
Word-with-blanks. You type in a letter and it either fills it in or adds
a strike. 3 strikes, move on.

Hmm, wonder if there's a $1 appstore app hiding in there somewhere?
Do some gaming theory research and see if we can turn it into crack.
