Mobile phone for blind and visually impaired – Sens

We created mobile phone named “Sens” for blind and visually impaired people.
After researches we finally started development together with a group from college for people with disabilities.
Visually buttons do not differ, but using a tactile sensation, they have significant differences. During studies and surveys we have concluded that the gaps between the buttons lead to indiscriminate perception, and the button “5” – uninformative.

Keyboard of Sens developed on the basis of feedback mode. When pressed, the input data does not occur immediately, but only informs the user about its purpose.
In the same way you can touch all the buttons and understand their purpose and the information which can be entered with the help of a button.

When the user knows exactly which button he needs to press, he can do it like on a normal phone. Entering of information is confirmed with the help of signals of different tone.

Thus, Sens system has an effective interaction with the user through the audio controller of input.
Sens has all the usual functions that are present in today’s mobile, but their usage is based on interactive touching and pressing the button if it is chosen correctly.

 
The biggest problem is that extraneous can hear your conversation, as here used loudspeaker. The problem was solved by Tokido Yoshida by integrating Bluetooth-headset which is used as a permanent device. Thus the risk of losing the phone is kept to a minimum, which is important for visually impaired people.The Phone is charging together with the headset, which makes usage of Sens easier.

 
Despite the defects, most people kept a certain degree of view. In some cases of defects, a person can perceive light of varying intensity. It is for them Sens has lights for incoming calls, Sms- messages and displays information about battery.
