The Future Usage of Smart Phones
by Rajakumar Arul (Student Member, IEEE), Gunasekaran Raja (Member, IEEE), Sudha Anbalagan, Dhananjay Kumar, Ali Kashif Bashir (Senior Member, IEEE)
Proliferation of the smartphone industry has made devices user-friendly, yet people with low or no visual ability have difficulty using them. The usage of smartphones is not always convenient, especially under certain circumstances such as travelling on a public transport, in social gatherings or when busy working. Senior citizens also experience difficulty in using new technologies. Therefore, today, most senior citizens in our society prefer to use traditional phones rather than smart devices.
Age is one of the major factors that restrict people in adapting new technologies. People over 70 years old often suffer memory loss and have difficulty in learning the usage of technical gadgets. Several gadgets, like blood sugar-level and blood pressure monitors, are designed for them, yet they need assistance in operating them. Apart from memory loss, poor vision and the user unfriendliness of technologies are other challenges that need to be addressed. For example, a grandmother is gifted with a smartphone powered by iOS/Android. She requires a mail ID to use it, though she does not need one otherwise and also needs some assistance to create one. After creating, she has difficulty in remembering the password. This leads us to a scenario that requires designing of interactive devices that are easy to use for senior citizens.
Another motivating scenario for interactive designing of mobile phones is for kids. Currently, the number of children participating in outdoor activities is decreasing. Rather they prefer to stay indoors and lock their potential by playing video games. So any device without interactive user interface will drain their interest in digital equipment. One of the easiest ways to do so is enabling devices with voice recognition. So they can operate devices using voice instead of complicated manual inputs.
The time is not far off when we will be operating our devices with voice. With some of the services like Google assistant, Cortana voice, etc., people have started using voice commands for browsing and typing. These services use online engines to convert voice into desired input. In the near future, the quality of these services will improve in terms of efficiency and voice recognition. Siri, an Apple application, is a good voice interpreter which understands the voice efficiently and does almost all operations required in the smartphone. Siri offers excellent features, but it still requires the keywords of the official language.
To meet the challenges of interactive interface with voice recognition , those of us at NGNLabs and Anna University are working with an aim of facilitating minors and visually impaired in using smartphones without much physical interaction with the device. Resultantly, our work will increase the number of smartphone and the internet users.
This proposed Intelligent Interactive Interface (I3) system will have a processor like Nios II  to do all the processing that is being connected with the memory controller, and it has an LED display to display only the components which are powered ON or OFF. It has a language analyser to differentiate the input language as colloquialism or official/formal language . Dialect differentiator similar to multilayer perceptron (MLP) is used here that acts as a classifier, since the usage of mother tongue differs among people. The jargon of the mother tongue, repetitive words, pause and pace being maintained throughout the talk follow a unique pattern for every individual. With the uniqueness of speech/talk the users can unlock the device and it can be operated only by the unique voice that it has been paired with or with a secured password. As we know, there exists a unique pattern between diverse voice and mother tongue cognition; our system should never lead to confusion even when a very large number of accents are spoken. In non-acoustic environments, our proposed design should act as a clean speech recognizer to recognize the voice it has been paired with. The mirror casting module casts the visual stream content to other nearby visual units like television, monitors, etc. to see the required visual outcome of the device -. The voice synthesizer plays a vital role in our design, which adds the predicted noise or tone that is commonly produced by an individual and checks for the unique pattern it obtained already. This way, we authenticate the voice paired with the device. It also has GSM/LTE and wireless broadband modules to provide voice and data connectivity using internet backhaul .
Figure 1. Components in the I3 Model
The proposed I3 model in Figure1 will adapt any short-run change of user voice, and an alteration in usage of words must also be learned by the learning network (artificial intelligence) that is inculcated in the device. Difference and distribution of voice is being identified by the energy at different frequencies. As per the neuro-heuristic voice recognition , the speech recognition system is under research and there exists a synchronism of voice as our brain stimulus responds immediately to recognition of voice (i.e., to find if the particular voice belongs to a known person or not). Not only the human brain, but even animals/birds can find their young ones among groups using voice as a primary mode and vice versa. So there is strong evidence seen that each and every voice possesses a unique pattern . Owing to the enormous and tremendous improvements in all fields, designing a circuit which recognizes uniqueness among various voices will be developed in the near future.
