摘要：Human Computer Interaction (HCI) with any computing device is becoming more important with the rapid growth of the use of such devices worldwide. Computing devices range from a computer (large, medium or small) to small devices, like a mobile phone. Since mobile devices are ubiquitous and many computing functions are moving to mobile devices, the need for a very good HCI is becoming even more important for such devices. While existing mechanisms are good for high end mobile devices (e.g. smart phones and PDAs), they mainly serve the technically literate people. Nontechnical, semi-literate and illiterate people have great difficulty in using existing interfaces, mainly because of the complexity in learning and the literacy needs. Besides, many people cannot afford such high end mobile devices. The User Interface (UI) for low end and medium end mobile devices are even more difficult as such devices do not have some of the nice features that high end devices have (e.g. touch screen, scrolling, larger size screen/keypad). However, complexity of learning is relatively less as such devices mainly have simple features and do not have complex features like accessing the Internet and interacting with Internet applications. Clearly, to provide the key benefits of this Information Age to many more people including largely dominated Base of the Pyramid People (BOP), low and medium end mobile devices should have all the key features that high end mobile devices, tablets and computers have. And such key features should have a very good UI. Two technologies are essential to achieve these goals – a Natural Language Interface and an Intelligent Agent. In this paper, we propose a Natural Language Understanding (NLU) based Intelligent Agent (IA) that overcomes the existing problems by automating the key tasks while allowing a natural user interface using user’s voice (or typing). Our solution not only makes it much easier to effectively use mobile devices by non-technical, semiliterate and illiterate people, but also by technical people as the key tasks in a high end mobile device now handled by manual scrolling and rendering by user’s eyes & brain are automated via the use of IA. We argue that such automation is, in fact, becoming a necessity when one would like to use various complex on-line applications including e-Services using low & medium end mobile devices. We also argue that our proposed approach makes the UI much simpler, easier and more effective for all other devices including high end mobile device, tablets and computers.
