Ex no 5: Teach a content using an interactive whiteboard

                 INTERACTIVE WHITEBOARD

An interactive whiteboard (IWB) is a large interactive display in the form factor of a whiteboard. It can either be a standalone touchsctreen computer used independently to perform tasks and operations, or a connectable apparatus used as a touchpad to control computers from a projeector. They are used in a variety of settings, including classrooms at all levels of education, in corporate board rooms and work groups, in training rooms for professional sports coaching, in broadcasting studios, and others.
The first interactive whiteboards were designed and manufactured for use in the office. They were developed by PARC around 1990. This board was used in small group meetings and round-tables.

              GENERAL OPERATION AND USE 

An interactive whiteboard (IWB) device can either be a standalone computer or a large, functioning touchpad for computers to use.
A device driver is usually installed on the attached computer so that the interactive whiteboard can act as a Human Input Device (HID), like a mouse. The computer's video output is connected to a digital projector so that images may be projected on the interactive whiteboard surface.
The user then calibrates the whiteboard image by matching the position of the projected image in reference to the whiteboard using a pointer as necessary. After this, the pointer or other device may be used to activate programs, buttons and menus from the whiteboard itself, just as one would ordinarily do with a mouse. If text input is required, user can invoke an on-screen keyboard or, if the whiteboard software provides for this, utilize handwriting recognition. This makes it unnecessary to go to the computer keyboard to enter text.
Thus, an IWB emulates both a mouse and a keyboard. The user can conduct a presentation or a class almost exclusively from the whiteboard.
In addition, most IWBs are supplied with software that provides tools and features specifically designed to maximize interaction opportunities. These generally include the ability to create virtual versions of paper flipcharts, pen and highlighter options, and possibly even virtual rulers, protractors, and compasses—instruments that would be used in traditional classroom teaching.
Uses for interactive whiteboards may include:
  • Running software that is loaded onto the connected PC, such as a web browser or other software used in the classroom.
  • Capturing and saving notes written on a whiteboard to the connected PC
  • Capturing notes written on a graphics tablet connected to the whiteboard
  • Controlling the PC from the white board using click and drag, markup which annotates a program or presentation
  • Using OCR software to translate cursive writing on a graphics tablet into text
  • Using an Audience Response System so that presenters can poll a classroom audience or conduct quizzes, capturing feedback onto the whiteboard

Ex No:1 How to operate computers

Connect the monitor, keyboard, and mouse, as well as plug the tower into a power source. We will be asked to create a user account when we turn it on. This account will hold all of our documents, pictures, downloaded files, and any other files that we create. Desktop appears every time we log into our account, and contains icons and shortcuts to our most used programs and files.  There will be a Start menu in the lower-left corner of the desktop. The Start menu allows us to quickly access our installed programs and settings. The mouse and keyboard are our primary means of interacting with our computer. Mouse allows for pinpoint navigation and control, and is necessary for a wide variety of activities. Click the Start menu and browse through the available programs.Installing software is a very common task on a computer, no matter what kind of computer we are using. The process is usually very straightforward, as most installers give clear instructions for each step. We can use mou...
