Abstract: Various displays are becoming available forimplementing a new kind of human computer interaction(HCI) method. Among many types and models, touchpanel displays have been used in wide variety ofapplications and are proven to be a useful interfaceinfrastructure. In spite of their popularity, there are someweak points. The most serious drawback is their hardnessto operate especially for the weak users in informationtechnology such as the elderly and blind users.

Haptic touch screen is becoming apopular interfacetechnology in mobile informationterminals such as PDAsand cell-phones . The operationalinterface used in themobile terminals is mainly inheritedfrom GUI interfaceoriginally designed for personalcomputers.
Touch screen terminals with thetactile feedback haveefficiency as assistive informationdevices.designed a method enabling blindusers to input text via thekeypad of a mobile phone
EVM – Technology Features Centres around state-of-the-art microprocessor with built-in PROM storing the software code which cannot be retrieved or altered Reliable, robust and error free software Legacy software with machine codes used to preserve integrity and security Double redundant resilient memory storage for securely retaining data without a need for a backup battery User friendly operation sequence Portable and easy to operate
Although the haptic technology is becoming animportant building block for implementingeffective andeasy-to-use interface, acquiring the state ofprincipalmodality along with audio-visual interface seemsdistant.A reason preventing the popularization of thehaptictechnology is that practical haptic applications arenot

Advantages Modernises the election process User friendly – can be used even by illiterates Simple to operate and can be installed in a short time Preserves voting secrecy No scope for invalid votes Facilitates quick and accurate counting – possible to declare results instantaneously Re-usable by simply erasing votes recorded in earlier poll
Advantages Huge expenditure involved in printing, storing and transportation and security of ballot paper can be avoided Lowers operating costs Easier to manage with less demand on man- power Provision can be made to connect to a “CENTRAL STATION” to consolidate and display / record the results countrywide
Conclusion-We proposed an approach for effectively sharingdifferent types of haptic devices and designing varioushaptic applications. We exemplified our approach throughthe design and development of an electronic voting system.The system uses an easy-to-use touch panel display withembedded tactile feedback function. It allows the weak ininformation technology such as the elderly and blind usersto easily confirm, select, and vote their supportingcandidates without any assistance. We conducted apreliminary experiment for verifying whether the systemcan generate tactile effect vocabulary effective fordiscriminating multiple candidates only through touchsensations. Although our project is at an early stage, theresult is promising.
