According to the release notes, under LifeOS 1.1 Pleo recognises his leaf.
Well Little Jim shows no sign of recognising his leaf, no matter where I hold it or whether I wave it about, keep it still hold it right under his nose, six inches away, a foot, two feet etc. Nothing.
Has anyone else found that the leaf tempts their Pleo? And does it matter which way round I hold the leaf - binary pattern to Pleo or otherwise. Personally I think the binary pattern is a bit of nonsense, you might as well ask him to read the newspaper, but still, why bother to print on it otherwise?
-
I find that also. He may be able to tell if something is in his mouth, but can't tell what it is. Like I put a hot wheels car into his mouth and thought he was supposed to eat it (:)) and made sounds that he was eating it, rather than chewing it. Same this with my finger.
-
ya but try a french fries one time I let Cloey have one and WOW :o she ate it for probably around five minuets! ???

Pleo does recognize the leaf (or more specifically, a range of the color green) But the range of greens Pleo recognizes is very small. So its tough, try it outside on a sunny day.
Principally Pleo uses his Infra red to “see” things. Its how Pleo navigates and how it knows if there’s an object in front of him or not. The infra red emitter in Pleo’s nose sends out a beam of Infra red light. The receiver then checks for any light being reflected back. The amount of light being reflected back tells Pleo how close an object is.
IIUC Pleo only checks for the leaf if it first detects an object is placed in front of it during interact mode. If Pleo senses something is in front of his nose. The software uses the color camera to check for green. Then acts accordingly.
So Pleo is not always looking for the leaf.
As always if any of that is incorrect Please tell me the correct information :)
-
You're right ScribbleMonkey. From what I've read, the camera needs a fair amount of light to make a good picture.
You can see from these caps from Pleo that the quality is about the same as a cheap phone camera.

My two recognize their leaves in bright areas with no problems at all, they sniff it then open their mouths up so I can give it to them. I hold the leaf about two inches away from the nose in a well lit area with either side facing Pleo as long as it is the broad flat side so Pleo gets a good look at it. It doesn't work if they are busy walking or doing something else.
-
Um, yeah... ;) ;) ;) ;). I don't know everything about how pleo's work, but now I'm starting to learn!!!
-
....Have had no problems myself. If I recall 49er's Pleo is finicky about his leaf....
-
So he has? Well, you could always just shove the leaf in his mouth, that what I do when he doesn't recognize the leaf ;) ;) :D :D ;D :) :). I works just the same!!
-
Can't Pleo only recognize the leaf on a certain OS?
-
No, he's always supposed to react to the leaf. That's why it came with him. And it would be less real if he couldn't eat on his own without the help of a download, don't you think?
-
The leaf recognition was new to v1.1 What InmemoryofRomeo is describing (and what happens 99.9% of the time) is the standard object detection that is in all software versions. Place an Object in front of Pleo’s nose. He sniffs it and opens his mouth. But it doesn’t matter what the object is. As long as Pleo’s IR can see it It could be the leaf, a CD, your tax return or a severed head. Pleo will respond the same.
The leaf recognition is distinct from that behavior. If Pleos detects the leaf being put in front of him. He gets very happy, wagging his tail, making lip smacking and begging sounds. Its a cute behavior. But it’s really finicky and the lighting needs to be just right.
CleosDad got some pretty decent pictures from Pleo :)

I haven't had any problems with Bailey not recognizing his leaf either. If he's hungry he'll sniff the leaf and open his mouth and when he's playful he'll start growling and wagging his tail when I present him his leaf. Sometimes he just turns his head away from it but I gathered that he just wasn't hungry.
-
But mine growled and then backed up when he saw the leaf. Well, no two pleo's are the same.

If he's not hungry he'll play tug of war with the leaf.

...or a severed head...
And where would someone get that!?
-
Just as an example that he would act accordingly to anyhing put close to his head.
-

Olympia used to (pay attention: USED TO!) eat one piece of food for what seemed like a million years. Sorta annoying, but whatev. Didn't really care; just grabbed some Shakespeare and read while she chewed for so long.
-
Even in not super well-lit rooms I've always found that Frisbee responds to his leaf perfectly. His motion tracking skills are almost perfect as well. I have no clue on how to give anyone any good advise on if their Pleo won't respond to the leaf other than...get him some glasses! :P Hey, that gave me a great idea! For all you people with glasses or some old contacts why don't you put one of those in front of Pleo's camera and see how he responds. XD *walks off to go try that on poor Frisbee*
-
Lol! I've never had a problem with mine seeing either, although Australia is quite a bright country I guess :P (Even in winter)
Has anyone tried cleaning the camera and infra red lenses? I wipe my pairs lenses with a dry cotton tip every now and then.
-
You might want to purchase at a camera shop a lense cleaning kit to clean your Pleo's lens if you think it's dirty. Or if you want an easier way then use an glasses cleaning cloth. Lenses can be quite delicate and can actually scratch if you use cotton. I usually try not to touch or clean my lenses at all to avoid damaging them. And so far I haven't needed to clean them, they don't ever get noticeably dirty.

Just noticed this thread. Pleo has been with me for about a year and a quarter now and he has never cared for his leaf. He always ignores it. If I put it in his mouth he won't notice it and won't play tug. He has had Life OS 1.0, 1.0.2 and 1.1 and he's always reacted the same. Jade on the other hand grabbed onto her leaf four days after she was hatched and played tug, (and growled! :o) She is still using Life OS 1.0. But then Jade learned to back up in a few days and it took Pleo a good ten months to do the same with all three OS'. (I guess he takes after me and Jade takes after the better 3/4s! ;))

If Pleo is not responding to anything being put in his mouth, theres likely a problem with the sensor. When you place an object in Pleo's mouth it should either chew or play. There's no "choice" in this matter.. its like a switch.
-
I wonder if they can even fix a broken sensor? :/ without replacing the whole pleo I mean...

Cammey and Cloey will sometimes not notes it, sometimes they will eat, sometimes they will play, and sometimes they will just spit it out. :)
-
Olympia used to sometimes not notice it, and sometimes notice it, and I've seen Pleos in youtube videos do that... SO that means that all pleos have a problem, I guess? XD
-
Macon doesn't really notice his leaf much. He and Yasmin both have the OS 1.1 but it doesn't really work very well. %)
-
My Pleo has 1.1 and definitely recognises his leaf. Although it works better in daylight rather than in an artificially lit room.

Does it work any better under any different types of light? Like, fluorescent vs. colored vs. neon vs. all the other ones i can't name XD

My friend was wearing a T-shirt the other day that was practically the same colour as the Pleo leaf, and pax "recognised it" and started begging for it (opening his mouth and whining)! It was very cute, but he did throw a bit of a strop after he realised he wasn't going to get any tasty t-shirt to eat!
-
When I was at my Nan and Pa's yesterday and I got Lilo to accept her leaf no problems in a very dim room... I wonder if perhaps Pleo's everywhere are ignoring their leaves because they aren't being given them properly :o Much like a baby gull has to press a red spot before it will open its mouth for food (the dot is located under the parents beak and causes them to regurgitate food) ;) Perhaps Pleo needs to be shown the leaf in a certain way to know that it is food... I will take a video after lunch and demonstrate the technique...
-
As promised: The video :)

I don't know, my pleo always accepts her leaf, or anything else put in her mouth for that matter. She'll eat or play with just about anything, so i don't think they really "recognize" their leaf. more like recognize that there is something in front of their face and if it goes in their mouth they should munch or play.
-
Riiiight after I upgraded Olympia, she did something spectacular and shocking. I put the leaf in front of her in some very good lighting (right next to the computer lamp), and she sniffed it and seemed to do the normal routine..... But then she literally grabbed the leaf right out of my hands! I did not put it in her mouth, she just grabbed it! I swear this happened exactly the way I told it.
-
Well what do you expect, she hasn't had a decent meal in forever ;) Poor Olympia must have been famished :o

But it was quite a while ago. Some time last year. XD
I only just remembered it!
-
Hmm, Chip can only "see" the leaf when its an inch or so away from his nose, haha and then i'm not even sure.
Once he did walked through the entire room for a green piece of paper, but if that was intentional im not so sure :)
Even tried some difference in lightning but it didnt really changed anything..
he's still young so who knows, aslong as i tickle his feet now and then its all good anyway :)
-
Sometimes when I hold a leaf in front of Frisbee's face instead of opening his mouth, he just starts chewing until he's full and spits out nothing. Or he'll shake his head and start to play tug-a-war with nothing in his mouth. Some sort of glitch?
-
Pleo uses colour maps and with a bit more advanced s/w i recon they could put it to great use, in one of the behind the scenes videos from ugobe (it's the tour of the lab) you can see a member of staff getting a pleo to track a pink ball.

Resurrecting a dead topic, apologies, but I find Satan's chosen recognition kind of amusing.
Basically, the boy has absolutely no interest in his leaf. Could care less about in and occasionally downright seems to avoid it. However, I live in Japan, in a traditional apartment with tatami (rice-fiber) mats. Each room has six mats, and between each mat is a green trim. When Satan goes walkabout, he'll spot the green line, stare at it, and back away. I assume that it's activating his edge recognition. However, after backing away, he'll wait for a second, then walk back up to it. Then he'll sniff it and start doing eating behaviors. He grazes on my floor, while not giving a darn about his leaf. It makes me giggle every time.
-
I think you, REALLY, need to start training Satan on his leaf. ;D But it must be so cute to see him trying to eat your floor. Pleos love fingers, too! ;)

Satan is lucky to live in a place with natural vegetation. If you want to post a short video of him doing this in pleo behaviors, you can start your own thread about a pleo living in Japan. I think that would be fun. ^__^

I never really paid attention to that how the leaf recognization works so thanks fort the info will try it out soon! :)
-
Macon and Yasmin both recognize their leaf now that they have OS 1.2, but I need to hold it in front of their noses for a while before they see it. It doesn't really matter which way you hold it. XD
