The Nexus 7 is the latest tablet built by ASUS for Google.

The biggest advantage of this device is it’s price. The Nexus 7 doesn’t compromise on quality and it most certainly doesn’t feel cheap or nasty. The entry level Nexus 7 come in at a £159 with 8GB of non-expandable built-in storage. There is also a 16GB version that will set you back £199.

The Nexus 7 has a 7 inch screen boasting a 1280 x 800 HD display (216 ppi), non-surprisingly this is nowhere near the quality of the iPad 3 (3rd Generation) with it’s 9.7 inch screen with 2048-by-1536 resolution and 264 pixels per inch. However when you take into consideration the price difference, you could argue that you get a lot more for your money with the Nexus 7.

A down side to this device is it’s lack of rear-facing camera, which could have added some extra assistive functionality to the device in the form of: taking picture, video magnification, with contrast and colour switching (through various apps) for assisting people with visual impairments.

Just like the iPad the Nexus 7 uses In-Plane Switching (IPS), basically this is technology that allows the device to have a wide viewing-angle, which ensures that the device can be held in a variety of ways without major viewing angle issues. IPS technology also aids better colour reproduction, meaning more natural tones.

Operating System

The Nexus 7 comes loaded with the latest version of the Android OS – 4.1 Jelly Bean. If you’re used to Android there will be no real surprises with this incarnation of the Android OS. There are however a few assistive improvements that can be activated under Settings -> Accessibility.

Accessibility Options (Jelly Bean)Android 4.1 Jellybean

Android’s language model has been given an upgrade, making it’s dictionaries more accurate, and adapt over time as the OS gets used to how you type, and what your common mistakes are. Voice typing has also been improved; working even when you don’t have a data connection, allowing you to type with your voice in any location.

Word Prediction

Another interesting feature that’s been added is word prediction which can come in handy if you easily loose your train of thought and can’t think of the next word to input.

Voice Typing

A new embedded speech recognizer lets you use Voice Typing without an Internet connection.

Gesture Mode

Gesture Mode can be used by people with visual impairments to navigate on the device using touch and swipe gestures in combination with speech output.

TalkBack

TalkBack is a screenreader that when turned on in Android’s Accessibility options, will provide spoken feedback to help visually impaired people to navigate the device. Android 4.1 now supports gestures to trigger actions, to navigate applications, and traverse text.

Braille Support

Android 4.1 now provides full support for braille accessibility services.
