machine interface with Projection Display

Hi,

I was investigating the possibility to use the TI DLP product for HMI.

 Only I was wondering how does the user interface?  Is it possible to use touch.

And is there a reference design I can use for it?

Thanks!

    Thank you for your question regarding DLP® technology.

    Just to clarify the request... Are you asking about a touch interface that would be similar to interacting with an Android or iPhone, only by touching the image projected on a screen or a wall; similar to some of the applications in these white papers?  TI DLP® Pico™ technology for smart home applications  ;  Advanced Interactive Display  

    Yes, touch is possible with DLP® technology, as you can see in some of the suggested applications in the white papers linked above.  Unfortunately, TI DLP® does not have an interactive touch reference design available on TI.com.  There are various 3rd parties that might have custom options, depending on what it is that you are looking for.  I am checking with some of my colleagues to see if any of our DLP® Standard chipset or DLP® Pico™ 3rd party design houses or someone else may have something to offer; hopefully I will have more information by the end of the week.

    I apologize for the delay in sending you a reply; many of us have been out of the office for the holidays.

    Happy New Year!

    Regards,

    Gary

    Gary,

    Thanks for the reply.

    I'm thinking of a 10 inch touch screen with HDMI that is connected to a qseven module.

    The reason why this is maybe an better alternative for a LCD screen: LCD screens are more aimed at consumer marked.

    I need something that is more suited for a industrial environment and available for at least 10+ years.

    I like the "Advanced Interactive Display " method. Only how far away needs to projected placed from the screen? And is there more information available how it is done?

    Thanks,

    EVS,

    For something to replace a relatively thin display like an LCD with touch-panel, the optics can get a bit complex (specialty mirrors and lenses, similar to what is used in ultra-short-throw projectors).  Making ultra-short throw projectors in a very thin profile tends to get pricey.  I am not sure they would be cost (or size) competitive with off-the-shelf industrial touch-screens.  

    On a seprate note, some of these DLP® applications and reference designs might be interesting... (I think some of the machine vision stuff is pretty cool, and maybe it applies in other areas of your application / products).

    Advanced light control – Applications - 3D machine vision

    Advanced light control – Reference designs

    I guess I should point out, TI does have a number of Touch Screen Controllers, Sitara Processors, and Factory Automation related products that might be helpful in our Industrial product lines. 

    Regards,
