In this chapter, we will show step by step how to design architecture for a multimodal system based on complex event processing , we take an example of put that there system because its reference the base of multimodal system.
4.1 Define the problem – domain
"Put That There” the bolt system is a voice and gesture interactive system implemented at the Architecture Machine Group at MIT. It allows a user to build and modify a graphical database on a large Format video Display. The Goal of the research is a simple, conversational interface for sophisticated computer interaction. Natural languages and gestures are used, while speech output allows the system to query the user on ambiguous input. Bolt’s System is primarily a voice-interactive

This is particularly evident with connected speech recognizers, which are nonetheless more attractive for many applica¬tions, as they allow more natural spoken input.
We use speech recognizers to transform speech to text using grammar below.
Grammar:
public = ()| (there) | (move) (that) | (delete)| (this); = create | put; = [a] (yellow | red | blue | black | green); = square | triangle | circle | rectangle;
The equivalence of the grammar using graphs: Figure 9 Graphs describe the grammar
Commands:
“Create or put”: “Create a blue square.” Effect of complete utterance is a “call” to the create routine which needs object to be created (with attributes) as well as x, y pointing input from mouse or eye Tribe.
“Move”: “Move that there” effect a displacement from old position the new one pointing by mouse or eye Tribe too. “Delete”: “Delete that” this command used to deleting an object by pointing input.
“There or this”: those command help to extract the pointing input from mouse.
The grammars above help us to extract only what we want as speech and ignore the rest. After using this grammar we extract sentence or words like:
• Create a yellow square.
• Put a red circle.
• There
• Delete
• This
• Move that
b) Keyboard and Mouse (input): After the speech the user can use the mouse with a simple left click, to point the position where he wants to create or select or
A text to speech (TTS) synthesizer is a computer based system that can read text aloud automatically, regardless of whether the text is introduced by a computer input stream or a scanned input submitted to an Optical character recognition (OCR) engine. A speech synthesizer can be implemented by both hardware and software. It has been made a very fast improvement in this field over the couple of decades and lot
* Contemporary voice-based systems, by contrast, are less costly, are more powerful, have better voice quality, and are less cumbersome for workers to use. Companies that have adopted newer-generation voice-based technology have reported increased productivity and higher pick accuracy.
M1 - Describe the features of an event driven language that make it suitable for creating a GUI
Event driven programs are also used in non-graphical applications as well such as real life objects like DVD Player, Microwaves Oven and washing machine also in operating systems such as CMD, PowerShell and
This consists of hardware/software performance, the characteristics of information and decision-making support provided to the user, system interface characteristics (Tan, Payton, & Tan, 2010, p. 236). The system interface, one of the major factors in system design, can determine if the system is easy to operate for experienced and unexperienced users. Based on their design, HMIS should be designed in a way that the end-users organize themselves, they should be able to incorporate approving factors (like graphics and color), and should have previous users’ knowledge in
Sign Language interpreters serve as a communication facilitator between student and professors, teaching assistants and other participants in meetings and classes. CART provides instant translation of the spoken English language into written English text that can then be displayed on a laptop monitor, which allows the student to read what is being said during a class session. Assistive Listening devices include a microphone with a transmitter unit, that is worn by the speaker, and a receiver unit with a headset or boots on a hearing aid user. The speaker’s speech is then transmitted to the student’s receiver unit via radio signal, which gives the student the ability to control the volume along with other settings. Accommodations are usually approved by a case-by-case basis, but new accommodations can be requested at any time. Even though the student’s preferences for an interpreter or CART is given consideration, it cannot be guaranteed that their preference will be

Generally, there are two key forms of monitor interfaces that should be highly considered in the process of designing different computer applications namely the multi-touch screen interface and the mouse-driven interface. The controlling actions that are carried out by different computer users tend to have different preferences when it comes to the use of different computer applications uses (Dearden, 2008). As such, the application of the multi-touch screen gives computer users an opportunity to interact with the computer applications via a touch screen that will give them a chance to tap, swipe, long tap, and pinch the screens for purposes of performing their required

Before developing the new system we have to look for existing system and what were the advantages in it and which were the reasons that forced to develop new system. In this chapter we will discuss about these in detail.
This chapter is dedicated to system architecture of event and temporal information extraction. In this chapter the model of the system is presented in detail. The first section of this chapter discusses our data source. The system is consist of four components the first component responsible for data preprocessing, the second for tagging, which contain different syntactic and semantic tagging tools, Stanford part of speech tagger, Stanford parser, HeidelTime temporal tagger, Stanford named entity recognizer. Third component is the extractor and finally the template generator. The components are discussed in detail afterward. The architecture is depicted in Fig 6.
Keyboard - The main job of the keyboard is to enter text, but you can also use combinations of keys to do some of the mouse jobs.
The proposed system has been implemented using three layer architecture. The functions of the system will be described briefly as follow.
David Crystal says that the spoken thing …has less grammar ‘because it does not follow the rules’ which are found in writing. Speech also is in utterances/sentences, but the kind of sentence organization found in speech is different from that found in writing. Writing is ‘polished’ unlike speech. The first thing that goes for speech is grammatical reduction; there is frequent use of ellipses and contractions. In writing the reader sees only the finished product, but in both these writers’ case, there is an abundance of the unfinished or unusually finished forms, as non-clausal or grammatically fragmentary components are the hall-marks of the spoken variety. They use this in a special manner – most of their parentheses fall into this category. Syntactic non-clausal units which can be single words, phrases, or unembedded dependent clauses. The following example is quite remarkable for the features which indicate spoken
