Direct Manipulation Principles

Direct Manipulation Principles furcate 1 DIRECT MANIPULATION PRINCIPLESThree Major Principles of Direct ManipulationProcess found on selection, interrupted and visible performance of objectProcess establish on selection is immediately displayed, which works fast, incremental and two sided actionsProcess based on selection utilise pointing action instead of typed commands (No Syntax)Advantages of Direct ManipulationBeginners learn QuicklySeldom put onrs can remember conceptsGetting error messages atomic number 18 not oftenUsers finds their actions argon promoting their goalsUser friendlyPotential Problems of Direct ManipulationVisual representation can be too detailhigh-level flowchart database schema can be seeded player confusingDesign may mislead 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 Hardw ar Technologies which detect multi-finger actionMicrosof t Surface and Microsoft Touch 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 knock-down(a) processors and intuitive interface, which is versatile and horizontal viewing.Microsoft Surface is multi-touch computer which grabs digital substance with your hands and move with simple touches instead of using mouse and keyboardMicrosoft Surface use camera and image recognition in a infrared spectrum to detect with sense 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 utmost resolution, pressure load.ProsIt makes convenient work space and easy to useIt is used in hotel to speed up the self check insIt is used in restaurants to en trap and pay from their tablesConsIt is very expensivePeople are more dependent on technologyMicrosoft Touch Wall MechanismTouch Wall is build on plex technologyPlex provides touch wall with fresh and fleshed out ways to prepare a natural interfaceTouch wall is large organization exhibit prototype and undergo collaborative workTouch wall uses a laser touch technique which observes infrared laser light speculating onward the users fingersTouch wall explores a different hardware configuration and multi-touch interaction modelsProsTouch wall is very intuitiveEasy to useSave aloofnessIt is faster pointing devicesConsIt is very expensiveSize of the device is very large and difficult to transfer from one place to another place.General Advantage of multi-touch fundamental interactionMulti-touch grabs digital substance with hands and more with simple touchIt is more flexible to learn understandUser can rotate and zoom the windowIt supports the interaction between different users.User s can switch between different task spontaneouslyInstead of making devices with different button, soft machines just win 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 described of Internet and multimedia enable smartphones designed by orchard apple tree Inc. some of the users have satisfaction on using the iphone and users appends 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 mobile industry iPhone increases service billing of about 24% because it displacing the notebook computers.orchard apple tree iphone increases some new application with the help of surveying by the iphone usersThe iPhone users has moderate capable problems who strongly agreed of 24%, lightly 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 touch modality of AppleIt has 16 GB 32GB flash drive, 3 mega pixel auto focusIt has Accelerometer sensors, proximity sensor and Ambient light sensorATT EDGE net 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 wish well 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 hav e 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 seldom have an issues like unable to connect near by Wi-Fi networks, giving every low signals and also sometimes unable to connect the internetIt cannot twine off the iPhone and unable to load data from the sync serviceiPhone cannot be unlocked 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 role of both selection and manipulation.DiscussionProsiPhone users are very satisfiediPhone increase mobile browsingConsIt supports SIM that has been activated for that specific mobile phoneIt Cant u pgrade the phone memoryiPhone battery cannot be changed and the fact that it is sealed bound DrawbacksIt is very hard to write in iphone because every time when we enter comma or any punctuation it is very difficult Suggestions
