CHAPTER 1 INTRODUCTION Every day of your computing life‚ you reach out for the mouse whenever you want to move the cursor or activate something. The mouse senses your motion and your clicks and sends them to the computer so it can respond appropriately. An ordinary mouse detects motion in the X and Y plane and acts as a two dimensional controller. It is not well suited for people to use in a 3D graphics environment. Space Mouse is a professional 3D controller specifically designed for manipulating

when water is detected. The whole unit is turned off when there is no flood detected‚ this can conserve power. When the water detected through the use of float switch that is located at the lower end of the stand‚ the whole unit will turn on. The ultrasonic sensor automatically measures the water level every 3 (three) minutes (the 3 (three) minutes intervals helps the system to conserve power) and delivers the data to the microcontroller. The microcontroller forwards the data to the GSM module‚ the

LIMITATION OF SIGHT AND HEARING INTRODUCTION Humans have sight and hearing limitation. Without any devices‚ our sight and hearing was limited. Most of the limitation of sight can be overcome with the help of certain optical instruments such as magnifying glass‚ microscope‚ binoculars and others. The range of frequency of hearing in human 20 Hz to 20 000 Hz. It was different according to the age of a person. Hearing limitations can be overcome by using devices such as microphone‚ stethoscope‚ earphone

define the criteria to be adopted for the design of such devices. In particular‚ attention will be focused on clear-path indicators‚ highlighting their role in orientation and mobility tasks. A new device belonging to this class is presented. The detector is based on a multisensor strategy and adopts smart signal processing to provide the user with suitable information about the position of objects hindering his or her path. Experimental trials demonstrate the efficiency of the device developed.
