My goal is to create a webpage that only displays a full screen video on a TV. Then have a second webpage someone could open up on their mobile device (via a QR code) and have a choice of 4 videos. Once you tap a video on the mobile device, it changes the full screen video on the tv. What is the best way to do this? I was thinking via a MySQL DB storing the webpage, then using JS to check if the content in the DB has been updated, and if it has, make the change on the tv. Is this the best way?

I'm creating a desktop application that assists in posting story on instagram, but I'm facing a problem. I use a cell phone simulation to open instagram, and to post instagram, it asks me to rotate the device. I've tried everything, but nothing works. I would like to know if there is any javascript function that changes the device orientation.
With the JavaScript Function
screen.orientation.lock("portrait")
or
screen.orientation.lock("landscape")
you can Rotate the Device in the Web View
I am making a WebApp that uses WebSpeech API for Text to Speech.
The problem I am facing is that whenever the screen goes off or
browser window is switched, particularly on mobile devices, the speech
synthesis is just stopped. When the text to be read takes longer time,
the device screen times out, the reading progress is lost, which is
really bad UX.
The basic synthesis controller is is created by const synth=window.speechSynthesis; which is attached to window.
I have overcome with a dirty workaround of keeping the screen on by using NoSleep.js, which essentially plays a video in the background to keep the device awake.
However, I noticed that some music players can play audio when browser is minimised and even when the screen is turned off. Example: wynk.in
Is it possible to achieve the same in my case? Any inputs on how is it done in music apps? Is attaching to anything other than window going to help?

How can I share the screen of Pepper's tablet? I wish to show the content displayed on the tablet on a projector so that it is engaging a larger audience. Is there any way to access it using the Java or Python SDK?
Yes, I often do that.
One way of doing so in NAOqi 2.5:
Make a webpage for your tablet content, formatted so that it looks good both on Pepper's tablet and in a browser window (so you need to use responsive design). See this, for example, on how to build a project with a basic webpage.
Store your state on the robot-side, e.g. in a python script / service; and the webpage should just be a watcher of that state (e.g. subscribe to a signal on a service, or to an ALMemory key). If you have buttons on the webpage, they should not directly change the display, but rather notify the python, which will in turn update the state which will update the webpage.
When running the application, display it on the tablet on usual AND with a web browser, open http://your-robots-ip/apps/your-app-id/, and put it in full sceen.
Et voilà! You should have a nice synchronized display on the tablet and the screen!
I'm building a web application (C#) for a customer.
Now I'm trying to add a page for mobile. I want that the customer will be able to scan a barcode (1D barcode or 2D barcode) and the code will be written in a text field (<input>) on the screen for further operations. It must work on android or iphone, and better - on both.
I tried to use JS codes which I can take a picture with the camera in the mobile device and the script reads the barcode in the picture - but I didn't find something good enough.
this one didn't work with large images from the camera, and this one couldn't read some of my barcodes and also couldn't read large images.
I tried to find a way that the customer will click on a button to open a barcode-scanner-application on the device (I have an android mobile device) - and the barcode will be written on an input on the screen, but I can't find if it's possible and how to do it.
I don't want to use phonegap - I need it as a web application, not a native app.
I am trying to integrate a webpage into an iPad application. Something like the Final Hour app where the app is a native app using slideshows. some of the slideshow pages have a small part that is loaded from a website.
The only way I would have known this was when I didn't have internet access the small area where the website loads into said there was no internet connection.
How can I implement something like this? I understand the website aspect but I don't understand what iOS API they use to setup some sort of canvas or frame to hold the website.
Here is an image of the app. The webpage would be loaded into the "blue" box outline.
You are indeed looking for a UIWebView. You need to build the controls yourself if you want your users to navigate in the website. If you just want to show one page, with no Back or Reload button, then you can use it as is.
Note that you should try to make it clear to your users that your app might not work properly if no Internet connection is available.
