It is often heard that the capabilities of the web move at a slow
pace whereas the native platforms move forward in leaps and bounds.
Hence, by the time we are able to use a new web platform feature, it
actually seems like a bit old hat. But the web as a platform is evolving
constantly and there are many features that could be used right now.
Here's a rundown of some features of the web platform that are comparatively underutilized.
Take photos
It is possible to access the camera of a device or photo roll straight from the browser, without requiring any JavaScript by using the following procedures:
Devices and Browsers supporting this can be used to take photo using the camera UI for that device.
Read files off your local system
With an image from the camera, it is possible to get details about the file, and also read the file's contents. And as it is not possible to read and write to the local file system, there is access to offline datastore with Web Storage as well as more sophisticated offline database with the presence of IndexedDB, and helping to be closer to those platforms.
Send system notifications
We find applications that send notifications of the arrival of a new message or completion of a lengthy task on our desktop systems, or mobile/tablet devices.
Our browsers too can use this feature on an increasing number of platforms by the use of web notifications API, which is supported by over 60% of browsers.
Vibrate the device
Although a common feature, vibration is no longer the domain of the native apps now. It is now possible to vibrate a device supporting vibration with a single call to the navigator.vibrate()method. The feature is supported in Android and Chrome, Firefox Mobile, the gap between the native and web capabilities being not that big.
Guess what you're doing
The browser now can guess where the user is right now and what is keeping him busy using a combination of data from gyroscopes and accelerometers (found in most phones and tablets, and often in laptop device), geolocation and some guess work.
Consider it to be cheap tricks?
Although what has been outlined here may seem simple and cheap tricks, but when considered as a whole, they provide the extent of capability of the web than what we know them to be.
The features mentioned are barely the tip of the iceberg. The coming years will see such offline technologies like Service Worker and Web Manifests that will make 'Progressive Web Apps' a reality.

Take photos
It is possible to access the camera of a device or photo roll straight from the browser, without requiring any JavaScript by using the following procedures:
- The input element of type file
- The Boolean capture attribute for the device to allow the browser in capturing input
- An accept attribute with a value of image/*, expecting an image
