[Xerte] Text Entry Hints

Ahh. Hadn't thought of that... I think of the total length of the word, but ¾ of the word is a pretty good hint...

Sorry, I'll sit down now. ;-)

-          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.

You mean 1/4 of absolute or 1/4 of the remaining blank spaces?

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.

You can see what I have so far at http://www.nottingham.ac.uk/~cczjrt/mediaInteractions/ <http://www.nottingham.ac.uk/%7Ecczjrt/mediaInteractions/>  - it's on page two.

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.
