Advanced Gesture Recognition System, Source released! Options

[Kyle_Solo]

Overview:
Ever played Black and White? If so, you must remember the innovative spell system, which required you to trace a spell's symbol to cast it. My gesture system allows just that. With just a few lines of code, you can add shape recognition to your games. It will take you no more than a few minutes to master the system. The help file also has an easy to follow step-by-step tutorial that will guide you through the process of recognizing a shape.

I think this is a good start. I don't know exactly what it would be used for, though.

* I noticed that you could draw a small shape or a large version of the same shape, did you use scaling for that?
* The recognition rate is low. If this were for an action game, I wouldn't want a critical gesture to be ignored.

EDIT: Can this be used for things besides the mouse? Like the keyboard?

Please disregard, this was for an old version.

You can adjust the recognition rate for each shape. You can also draw shapes scaled however you want. This is almost a bug, because it lets you draw a rectangle and interprets it as a square. I'll work on it. Yes, it could be used for the keyboard, maybe. It lets you set the x,y it captures, so you could come up with a system that works based on that.

EDIT: Bug fixed

Suhweet! Im gonna use this in the game im making, I'll be sure to credit you

How did you handle the scoring in yours? In mine, I allow two type of definitions to be made. You can either add points to a grid or create a directional string. One doesn't affect the other. Dot product is used when scoring point grids, and a string similarity script is used when scoring directional strings. It's all done in the gesture_score() script if anyone searches. The directional string definitions are less accurate than the point grid ones, but I've managed to always get the right shape when drawing the point grid definitions. I don't know why anyone else has had difficulty, but I explained how to make things easier to draw.

You linked to yours in mine, so I'll do the same, heh heh.

Mine uses a bizarre method of comparing two arrays of points. It score based upon the difference it calculates between them. It's more advanced than it sounds, trust me.

Fine by me. I would encourage readers to try both.

By the way: Major update! Please re-download. This version is much better. Now has a shape creator and nice demo.

I do believe. This new demo is amazing! I can't believe I didn't think about putting a shape creator in my version after all of the other things I did. Great idea. I'm having greater success with your shapes in this version than did the last. I don't know if you changed the underlying code or just the settings, or whether my hand has just gotten a lot steadier over the last few weeks :-), but it seems better. I wish others would pay this and my own a little more attention, seeing the work that was put into both.

Thank you! I worked pretty hard on this. I actually felt the need to improve it when I saw Point Magic. I am currently working on even better recognition. Specifically, better recognition for bigger shapes (right now smaller ones are easier to recognize). A stupid bug is keeping me from testing it. It works fine as scripts, but when I package it into the extension is gives a weird error. I'll hunt it down, never fear.

EDIT: Found it. Still needs some work though. I posted a record of the error here. Not my fault!

EDIT: I've fixed the recognition for bigger shapes. They are now recognized exactly the same as small ones. Pretty cool, huh?

Wow, you did all of this in the short time that passed since I released Point Magic? You work fast! I'm happy my little presentation gave you extra motivation. :-) I actually like your presentation more than mine. It has a slicker, more professional look.

I figure people won't truly appreciate these kind of things until they see them put to use in a game. So I'm going to work on that later on and at least one other example/program, and then I'll post a video or something so people can actually SEE that these things work since it seems that it's hard for new users to get the drawings down.

Update! Version 4.3 supports more accurate scaling of gestures. The cutoff argument is now different. It should be about equal to max(widthofshape,heightofshape). In previous versions large shapes had a much smaller chance of being detected, now the chances are equal! Download link in first post. The demo has also been updated to reflect the changes to the cutoff variable, and I made it more pretty (I was bored). To anyone using this in a game (anyone?): use the updated version! It might be a pain to update the cutoff, but it will work much better.

Next version:

I'm drawing a blank here...
What would you like to see in the next version?

I extracted it but it still says : cannot find extension pacage:gestures. how do i fix this?

[Kyle_Solo]

You need to install the 'gesturesXX.gex' extension. (XX being the version number)

ok i did it, it works now.

cool extesion... could be very useull.... you should make it so you can start drawing from any part of the shape and it wil still reconise it instead of having to allways start drawing the circle from the top..

[Kyle_Solo]

I don't know if you changed the underlying code or just the settings, or whether my hand has just gotten a lot steadier over the last few weeks :-), but it seems better.

A little of both. I changed the code slightly, but most of it was the settings. I didn't know it would react to shapes with points only at the corners. It reacted poorly. To everyone: You have to carefully define your shapes. For 4.4 I will be adding a gesture_shape_subdivide function to make it easier. (Added)

you should make it so you can start drawing from any part of the shape and it wil still reconise it instead of having to allways start drawing the circle from the top..

I thought about it, but it would be very hard. Very hard. You can't even begin to understand how mindbogglingly hard it would be. It would also slow the system down a lot. Don't count on it.

It's too bad that most of the people around here don't like to be challenged.... You should make a little game with this and release it in Creations. We can challenge each other, since I'm making a game of my own (and a nice little program). :-)

Update! 4.4 is now out, with new features, including a better help file which contains a tutorial. Also, two new functions have been added and the demo has been slightly updated to reflect those changes.

[oakwhiz]

I think this will be useful for my Nintendo DS simulator. *puts into pile of extension packages*

[death-droid]

looks cool just about to try out

EDIT:Very nice 10/10


one question are you able to make it so it has that effect that goes along the line as soon as you draw anything and can you make it do stuff if you make a shape??

Any idea why GM would tell me that the extension is corrupted?

[Alex]

These aren't that hard to make. Although, I haven't actually tested it. I made a hand writing to text converter a long time ago. I assume it would be similar.
