Voice, face, or movement recognition is not new but it allows to develop awesome devices.

Movement detection in Kinect

Kinect was introduced in 2010 and became popular in 2011. It is one of the best selling game devices. It has changed the way we play games (playing games without using controllers). The users now are “controllers”!. Maybe in the near future, with this technology, we won’t need remove controllers to control our TV.

Siri on iPhone 4S

The idea of using voice for interacting with devices is not new but Siri is the best voice interaction tool we have ever had on a real mobile device. After Siri, many other voice based apps have been announced.

Cloud services

This idea is also not new. The basic idea is to put all your data on cloud automatically so that you don’t need to worry about the failures of data storages and you can access and edit your data anytime and anywhere. However, in this year, with Cloud Derive and Cloud Player of Amazon, and iCloud of Apple, the cloud becomes popular.

Face recognition

In the beginning of this year, Facebook integrated the face recognition into their automatic photo tagging function. FB can automatically find and tag people in a image based on the face database generated from previous images. The face recognition is also used in Android 4.0 for unlocking Android devices.

Google auto driving cars

Google introduced their fist auto driving cars based on Google Maps and obstacle detection technology this year. Although they have encountered some accidents and problems with these cars, this technology provides promising results for future.

Glassless 3D

Several devices having glassless 3D screens were introduced, such as Nintendo 3DS and HTC EVO 3D. Although glassless 3D is now not very good and can make your eyes tired, it may be an important trend for 3D technology.

After Amazon introduced Kindle Fire in last September, Barnes & Noble also introduced their new Nook Tablet. Both tablets has similar features. The main hardware differences are RAM (1GB in Nook Tablet vs 512MB in Kindle) and storage (16GB in Nook Tablet + SD card expansion vs 8GB in Kindle Fire). With a higher specification, Nook Tablet costs more than Kindle Fire 50$.

The advantage of Kindle Fire is the support from Amazon digital store (e-reader, apps, music, games, videos…) and Amazon cloud service. However, Barnes & Noble provides Prime as an alternative.

If your Android device is rooted for using a cooked ROM, you should install 2 useful apps, Root Explorer & Titanium Backup, for backing up data and deeply accessing the device system.

1. Titanium Backup

This app helps us backup and restore apps and their settings. We can backup manually or automatically by setting a backup schedule. This app also provides other useful functions:

- Freeze apps that are installed but do not work properly.

- Uninstall system apps and installed apps .

(Note: the batch backup/restore functions are only available on Pro version).

Link download

- Version 3.9.0.1: http://www.mediafire.com/?0e4pc4zuejgcx4s

 

2. Root Explorer

This app is used to access to the storage and sd card of your Android device. We can modify the device system with this app, such as overclock, copy files *.apk, and delete system apps.

Note: if you copy any file into system, don’t forget to set permission for it. If you don’t set the permission, errors may occur during the booting process. For example, if you copy file “framework-res.apk” and forget to set permission for it, you device can not start.

Access to “system/app” folder where the apps of the cooked ROM are stored. Now you can delete apps or copy new apps into this folder. To copy or edit apps, you must change Mount R/W to Mount R/O as follow:

- Set permission for apps before using. Touch on the app that you want to set permission in 2s to display the Option dialog and choose “permissions”.

- Check all boxes and click OK. Reboot your device.
