How to develop algorithms for eye-tracking using labview

Working on a senior project using vision builder, labview, and NI camera 1712. Unfortunately, none of us in the group has had a lot of exposure to working with any of it. So far, we've been able to have the camera to identify the eyes as well as developed a program that allows us to type in points in x and y coordinates and moves the mouse to those coordinates on the screen. Now what we want to do is sync up that eye movement so that the mouse cursor will move based on eyes rather than typing in the location. Could someone please help us with developing/pointing us in the right direction of how to create the algorithms that will allow us to use the real-time tracking of the eyes to moving the mouse cursor?
Thanks a ton in advance!!! =)

Hi ashya09,
It sounds like you're close to getting your application working! Could you provide some more information on how you have both of these parts of your application implemented so I can help explain how to tie them together?
I'm assuming that you're using a Call Library Function Node with the SetCursorPos command to change the cursor position. Right now you're probably using controls or constants to wire in the position. You should be able to do the same thing but instead wire in an output from your eye identification. What function are you using for your eye identification? If you give me more information on this function I should be able to point you towards the right output to use.
Thanks!

Hi where can I learn how to develop app for ios in Singapore?

I am new to iOS development. Are there any courses from apple or elsewhere in Singapore that I can learn how to develop apps for iPad and iPhone platform?
Thanks.

There are a number of good resources. Stanford did indeed start up the iOS development class again, but the registration period has passed. You can stilll download the material and do a self-study, though:
https://itunes.apple.com/us/course/coding-together-developing/id593208016
There are also Apple's materials, the primary source of development information:
https://developer.apple.com/devcenter/ios/index.action
If you do a web search for "iOS development", you'll find a number of other sites that should be of help.

How to set value for trim and bleed using jsx script?

I have tried using bleedoffsetRect but somehow it is not working. Can anybody please help me on how to set value for trim and bleed using jsx script? Any example will be highly appreciated.
Following is the code I am trying with:
var _saveName = new File ( root_path +_strFileName+".pdf");
    var _saveOpts = new PDFSaveOptions();
    _saveOpts.printerResolution = 300;
    var bleedarray = new Array();
     bleedarray[0] =9.00;
     bleedarray[1]=9.00;
     bleedarray[2]=9.00;
     bleedarray[3]=9.00;
    _saveOpts.bleedOffsetRect = bleedarray;

I would expect although I've not actually tried this for the bleed off set box to be larger than the artbaord and the first two values to be negative or 0…
var bleedarray = new Array(-9,-9,artboard.width+9,artboard.height+9);
Where 'artboard.width' & 'artboard.height' you will have calculated from your file. An Array(9,9,9,9); would not constitute any boxes bounds.

Download the apps on your syncing computer and then sync to the iPod. Note that you can only sync apps for the one syncing computer you use with the iPod. You can manage music and videos among different computer.

WRT54GL V 1.1 : how to reserve IP for specific MAC address using DHCP

My !free! made in China router have this functionality. And yet I have been banging my head with this new reasonably expensive wireless router from Linksys. Anyway I lug my notebook around. I need my home router to be able to automatically configure notebook IP address using DHCP. At the same time I need the ip given by home router through DHCP to be the same IP all the time. So "static" ip is not the solution. Alternative "static" ip is also not a solution. Anything with the word "static" in it is not a solution. I know about third party firmware (wrt or tomato) and I know WRT54GL can be flashed with this third party firware. But I'm not going to void my warranty. This will be my last option but not the solution that I seek. I would like to know how to reserve ip for specific mac address using DHCP for WRT54GL V1.1. If this version have no way to make such configuration, I would like to know if there is official firmware upgrade that address this. Thanks in advance!

Maybe these could help. (Images extracted from the User Guide)

How to read data from a router by using labview

I am a beginner labview. How to read data from a router by using labview ?

What kind of data are you trying to read?
Does the router behave like a webserver that you log into? If so, search the forums for threads discussing HTML.

How can i write the data to PIC16F819 using labview?

how can i write the data to PIC16F819 using labview?
Need help!
im using labview in gathering the datas that i need to right to the PIC, then after getting all the datas i am using another program which is ICD2 in order to write it to the PIC. Is it possible to do this task through LV? coz we are spending a lot of time transferring the data from LV to ICD2 manually and its prone to mistake as well.
any suggestion?
thanks,
Pedz

LabVIEW does not currently have a built-in method to communicate with
i2c, but there are other vendors that sell devices to communicate in
this manner with LabVIEW development kits. One that I know of is
from MCC... here is a link: http://www.mcc-us.com
They sell a device called iPort, and then you can buy LabVIEW VIs to go with it. I hope this is helpful to you!

How to run MRP for Bulk Material without using LTP

Hi, how can I run MRP for BULK material without using LTP.
Thanks in advance
BK

Hi,
Use trasnsaction code OPPQ and goto BOM Explosion and selection depends on
Field selected
No dependent requirements are created for informational purposes for bulk material items in the plant selected. This can improve system performance.
Field not selected
Dependent requirements are created for bulk material items in the plant selected. These dependent requirements are displayed in the planned order for informational purposes only. They are not considered in the net requirements calculation; that is, they are not included in material requirements planning (MRP) and are not displayed in the stock/requirements list

How to generate and print 20x20 datamatrix barcode using labview?

Along with the barcode certain datas are to be added to the right of it.

Since you started a duplicate thread - I'm going to continue in here.
We have given you a number of different options to generate/print a barcode using LabVIEW.
Do you have the Bartender software installed with the Automation (ActiveX) option? Can you print a label from within the Bartender Software? Do you know how to call ActiveX functions in LabVIEW? For the latter, if you Google 'calling ActiveX LabVIEW' you will get a lot of results. Once you know how to do that, you just need to know which Bartender ActiveX functions to call.
I've attached a couple of screenshots from some quick code my colleague put together before to initialise Bartender, open a label template, fill in a field and print a label. Don't forget the close the references when your application exits. For more information you'll need to read the Bartender documentation.

General framework for computer based training using Labview

Hi, I work as an instructor and I am a beginner in Labview-programming.
I want to use Labview vi's that I've found here and there, in a tutorial framework, so that the student can get access to vi's in a consecutive mannner.
I believe that by adding text to simulations found here, I can make a solid tutorial in let's say signal processing for my students (military).
I would need a framework which allows me to insert vi's in a structure containg buttons "NEXT" , "BACK" and "Back to Top".
Archangel, helped me with an event structure found here, but there one can only return to the top-level. I want to be able walk back and forth from subvi to subvi , with "NEXT" and "BACK".
If one has a tutorial with many parts, it would also be nice if one could go directly to a submenu directly from the top. So that the students doesn't have to click "NEXT" a bunch of times, to reach there.
See the attached, if you don't understand what I mean.
Can somebody help me with that?
Kindest regards,
Lasse

The solution will depend on how many steps you have and how easy you want it to be to modify them. The classic way to do this sort of thing is to use a tab control with hidden tabs. Each tab is one step. As you go from one step to the next, programmatically change the page of the tab control which is visible. This works for small numbers of steps which do not have lots of code behind them. For larger numbers of steps, the tab control is replaced by a subpanel control, and the steps are independent VIs loaded into the subpanel. I would recommend this architecture if you want a generic one. You can find information on using subpanels in the LabVIEW help and here.
Good Luck!

How to create a strictly typed refnum control using LabVIEW scripting

I wish to use LabVIEW scripting to create a strictly-typed refnum control that is bound to my custom control (a type-defined cluster), but I'm unfamiliar with scripting and can't see how to do it.
If I create a New VI Object, using Control Refnum as the Style, how do I provide my custom control to the VI Object Class terminal? When I try using a reference to my custom control.ctl file (using Open VI reference) I get an error: "Error 1057 occurred... Type mismatch: Object cannot be cast to the specified type."
Or, if I create a new Control Refnum as above, using a standard Cluster as the VI Object Class, how do I then convert this refnum control to a strictly typed refnum that is bound to my custom cluster control type?
Thanks in advance for any advice,
Thoric (CLA, CLED, CTD and LabVIEW Champion)
Solved!
Go to Solution.

Here we go...
You have to create a new Control VI and then specify the VI Type as Typedef.

Building SCADA software for substation automation control using LabVIEW

Hi, I would be interested to know if anyone has built or developed a SCADA software for substation automation control using purely LabVIEW and its add-on tools (beside NI LookOut). The SCADA software, somehow similar to WinCC, should fulfill basic SCADA function for substation such as monitoring and interlocking control of CB and DS (single/double point), generate event or alarm list which includes information such as topical/not topical, valid/invalid...., archiving, redundancy, etc.

Hi Remzi,
Thank you for your information.
I understand that the DSC Module is a tool capable of developing monitoring and control system. Using the module would enable me to build a SCADA software (similar to LookOut) according to my requirement. But I think it's quite a difficult task to design and build a SCADA software from the scatch. Unlike a SCADA software, the DSC module is not really a SCADA software where user can directly parameter the I/O points and graphics via GUI. I've actually tried the LookOut software, but found that it's not really suitable for substation automation & control field. Hence, I would be grateful to know if anyone in this field has developed similar SCADA software for substation automation.
Best Regards,
Edmund
