How to place wrist watch if human wrist gets detected?

August 7, 2012 - 2:36am #1

Hi all,

I am completely new into AR technology, I do have knowledge of iOS native code application.

I have searched about several APIs/SDKs but I found this vuforia - a better option.

I have also referred this site and given example, and I do really find its awesome. So I would like to know how to create my own application with the same.

From where and how do I start?

My project requirement is like this:

  • I have several wrist-watch images, so user will pick one out of those
  • Then camera will get launched and user will put his wrist into that
  • Camera will automatically detect that human-wrist and place the watch at the right place.

After that user will also be able to take a picture of that screen.

Questions: 

  1. What I found is AR code is normally base upon markers? So how to create and detect human hand/wrist as a marker over here?
  2. Also how to place selected wrist-watch image at the particular position?

Waiting for the reply.

Your best bet is to study the Image Targets and Framemarkers samples as a starting point.

Basically you could use either of these as a recognition starting point and place the image on a paper band of some sort and then get the software to augment a model on top.

You can also read the dev guide as well for more info.

Thanks for the reply David.

Can you please help me send some links/codes or any existing demo related to the same concepts, where we can identify the real time object.

I have got your point that we need to identify through 2D image and then place model object over that.

Thanks in advance.

Vuforia is capable of detecting and tracking planar (i.e. flat ) images. It's not going to be able to detect the shape of a wrist. But you could develop the application that you've described by having the user place an image on the top of their wrist. This would serve as the target and enable you to render the watch model in the appropriate position on the user's wrist. But keep in mind that the rendered model is drawn on top of the camera image. This means that the model will always be drawn over the view of the user's hand and wrist. So if the model is a full loop, even the portion of the band that should be underneath the wrist will be rendered on top of it. For this reason, you'd probably want to use a partial model of the watch, which only presents the area that should lay over the wrist - e.g. the user's perspective when looking at the face of the watch.
