Title: Public Issues on Projected User Interface
Authors:  Ju-Chun Ko, Li-Wei Chan, Yi-Ping Hung

Summary:


This paper discusses projection technology and how the environment and the social aspect of our lives. Mobile devices that can actually project media in a public space can cause several problems.

The first topic discussed is projection as an intruder. If somebody is in a public space, like a bus stop, and decides to sort his pictures with a PUI device it could be distracting to people around him. The question is brought up if bystanders have the right to refuse projection because the big display forces people to notice the content that is displayed. Also, the projection could easily invade somebodies personal space.

What if everybody in the future has a mobile pocket projector? This could cause problems with overlapping displays everywhere.

With so many projectors around there could be a problem with human rights. What if somebody is projecting on another person? There are suggestions of having people object to being projected on, or simply having sensors for people that don't want to be projected on. The sensor can detect the light and send a decline message to the device.

Light pollution in the form of glare can come from these devices. The solution discussed is have the device detect if a human face in its projection field and darken these regions.



Discussion:

This paper seemed kind of ridiculous. I could see how this would be an issue but it just seemed kind of weird. The scenarios from the pictures are many people walking around with projector devices attached to their chests and invading space and bothering people. If this were the case I could understand. If it turns out to be like this then I agree this may need to be addressed. It just seems like a weird topic to actually write a paper about and be legit.

I would argue that most people keep to themselves anyways and would prefer not to project things from their devices in a public space.

  1. Yeah, I'm with you on this one. It might be because I've never been shot in the eye with a pico projector before, but I can't see these scenarios ever coming to fruition in the manner the authors suggest it might.

  2. I agree, this would be a very unlikely way the world turns out. If pico projectors do become big, then the devices will more than likely come with personal displays also for situations such as this. And with privacy being such a huge issue, I would think that people wouldn't want to broadcast their life in a public space.

  3. This is possibly one of the most pointless papers I have read thus far. What is the difference in privacy concerns in a a projected screen and a physical screen? Can't someone read your laptop just as easy as they can read your projected screen? And sure I would be mad if someone pointed a projected in my face, but I would be just as mad if someone pointed a flashlight in my face.

  4. I completely agree with you. Not only that, they didn't even talk about PUIs, it was all about portable projectors and the problems they have. This article was behind on the times. Check out the vid on my post, it was from Feb 2009 and is way ahead of this article from April 2010.

  5. I agree with your views. If pico-projector use ever got to the point where everyone had one strapped to their chest, than the issues brought up by the authors most likely would be an issue. However, the likelihood of that ever happening seems slim to none.

  6. I thought this article was pretty ridiculous as well. Why are the projectors strapped to people's chests and why is a guarantee pocket projectors will ever be truly popular? I'm not buying it.
