The design and implementation of a gravity sensor-based mobile phone for the blind

The paper raises an implementation method of common Android mobile phones with gravity sensor for the blind. The methods utilizes gravity sensor to recognize the position status of the mobile phone for the blind and encode the status; thus, the blind can operate the mobile phone just by changing the position status of the mobile phone; therefore, even without visual sense, the blind can still dial, answer a call, send and receive short message, play music on mobile phone and operate other functions of common mobile phones. The above mobile phone is easy to operate with no need of adding new hardware; compared with other mobile phones for the blind, the mobile phone is featured in lower cost; besides, the above phone by the method can be switched between common mobile phone and mobile phone for the blind as per the demands, and thus normal people can also experience the new operation methods.
