Direct Manipulation Principles

Direct Manipulation PrinciplesPART 1 subscribe MANIPULATION PRINCIPLESThree Major Principles of Direct ManipulationProcess based on selection, interrupted and ocular performance of objectProcess based on selection is immediately displayed, which works fast, incremental and deuce sided actionsProcess based on selection using pointing action instead of typed comma butterflynds (No Syntax)Advantages of Direct ManipulationBeginners examine QuicklySeldom users can remember conceptsGetting error messages atomic number 18 not oftenUsers finds their actions are promoting their goalsUser friendlyPotential Problems of Direct ManipulationVisual representation can be also detailHigh-level flowchart database schema can become confusingDesign may guide to their goalsUser must know the meaning of images which is displayedTyping commands or using short keys with the keyboard may be fasterPART 2 MULTI-TOUCH INTERACTIONTwo Hardware Technologies which detect multi-finger actionMicro buggy pr oscribeddoors and Microsoft conjure wall are some of the two hardware technologies which detect multi-finger action.MICROSOFT SURFACE MICROSOFT TOUCH WALLMicrosoft Surface MechanismMicrosoft Surface has a rugged table top structure, with powerful processors and intuitive interface, which is versatile and plane viewing.Microsoft Surface is multi-touch computer which grabs digital substance with your hands and move with simple touches instead of using grovel and keyboardMicrosoft Surface use camera and image recognition in a infrared spectrum to detect with palpate of objects such as fingers, tagged items shapesThe input is then processed by computer and the sequent interaction is displayed using rear projectionMicrosoft Surface is based on Windows Vista SP1 operating system and it has 30 inch XGA DLP projector with maximum resolution, pressure load.ProsIt makes convenient work space and scant(p) to useIt is use in hotel to speed up the self check insIt is used in restaurants to order and pay from their tablesConsIt is very overpricedPeople are more dependent on technologyMicrosoft preserve Wall Mechanism hit Wall is built on plex technologyPlex provides touch wall with fresh and fleshed out ways to produce a natural interfaceTouch wall is large organization exhibit prototype and permit collaborative workTouch wall uses a optical maser touch technique which observes infrared laser light speculating off the users fingersTouch wall explores a contrary hardware configuration and multi-touch interaction modelsProsTouch wall is very intuitiveEasy to useSave SpaceIt is faster pointing devicesConsIt is very priceysizing of the device is very large and difficult to transfer from one place to another place. frequent Advantage of multi-touch interactionMulti-touch grabs digital substance with hands and more with simple touchIt is more negotiable to learn understandUser can rotate and zoom the windowIt supports the interaction between different users.Use rs can switch between different task spontaneouslyInstead of making devices with different button, soft machines just draw a picture of the devicesPotential problems of using multi-touch InteractionIt is very expensiveSize is very bigIt requires two hands to operateOn large displays many objects are out of focusVery object of the user is manipulatingIt has reflective display but it is not usable in bright sunlightsPART 3 SURVEYMulti-touch Interaction Supported in the user interface of iPhoneiPhone is expound of Internet and multimedia enable smartphones designed by Apple Inc.Most of the users have satis positionion on using the iphone and users increases the usage of email data functionBy surveying the iphone users, they have previous apple experience and they are technically sophisticated, most of the iphone users are students and age under 30 years.In busy industry iPhone increases service billing of about 24% because it displacing the notebook computers.Apple iphone increases some new applications programme with the help of surveying by the iphone usersThe iPhone users has moderate capable problems who concentratedly concord of 24%, Mildly agreed of 38%, Mildly disagreed of 28%, Strongly disagreed of 10%iPhone runs an operating system known as iPhone OSThe operating system of iPhone run the software which is approved by the signature of AppleIt has 16 GB 32GB flash drive, 3 mega pixel auto focusIt has Accelerometer sensors, proximity sensor and Ambient light sensorATT EDGE network speed is very low.The 66% of iPhone users says it is best, which is followed by 45% of touch screen interface, easy to use 22 % and size of screen 16%Users a exchangeable(p) iphone because it come with great application like email GPS MMS etcUsing iPhone in business is to speed up the day, like quick call, calendar, web browsing, strong contacts and smart features like GPS maps , weather report etciPhone helps the users to cook because it has Apps of the cooksiPhone also have great application like Apps for keeping current news, Apps for outdoors, Apps for music, Apps for work, Apps for students, Apps for business, Apps of going out and finding places to eat, Apps for Games and funWi-Fi networks rarely have an issues like unable(p) to fall in near by Wi-Fi networks, giving every low signals and also sometimes unable to connect the internetIt cannot turn off the iPhone and unable to load data from the sync serviceiPhone cannot be unlock formally because the lock and unlock authority is maintained by the Apple servers.Using both Multi-touch Interaction and Direct Manipulation MethodsIn Apple iPhone the both Direct Manipulation and Multi-touch Interaction are used by Multi-finger cursor techniques.Direct touch interaction is appealing because they can play a division of both selection and manipulation.DiscussionProsiPhone users are very satisfiediPhone increase mobile browsingConsIt supports SIM that has been excited for that specific mobile phoneI t Cant upgrade the phone memoryiPhone battery cannot be changed and the fact that it is sealedLimitation DrawbacksIt is very hard to write in iphone because every time when we enter comma or any punctuation it is very difficult Suggestions
