Mobile Phone-based Interaction Techniques Essay -- Technology, Bluetoo

Many of the research beed in the field of study of industrious phone-based interaction techniques that have been developed so far number into three main classes according to Sas & Dix 21. In some research, the personal construction effectively acts as an extended input contrivance for text redaction or pointing task. In others, the phone is used to upload and download media development standard content and protocols. The third class is where the mobile phone is a more integral part of the interaction, typically using the display of the thingummy in concert with the public display. Ballagas et al 7 present a s washbowl of the existed interaction techniques that use mobile phones as pointing craft. Alongside with the survey, they present an compend on these techniques based on the following taxonomy position, orient, select, path, quantify, and text .The study concludes that the mobile phone is suitable devise for positioning tasks in various slipway especially when intera cting with public display in pervasive environment. Bellow we present some studies based on Sas & Dix classification 21.Mobile phone as pointing devise As a research area, several studies use orbit processing and visual recognition as a base in there interaction technique, since that most of the smart phones and hand-held devices are furnished with digital camera. Jiang et al 1 attempted to take advantage of this fact by proposing a study to interact with display through mobile device camera. There method uses the position of the cursor on the display as the basic input source. The presented systems depend on a closed-loop of feedback between the handheld device and the display to provide continuous-visual feedback. This closed-loop starts with presenting the cursor on the display. Then, th... ...sts of three units the Symbian node application running on the mobile phone. The role of this unit is to modify users to select a track from the presented list on the phone screen. Th e here and now unit is the server application running on a PC which counts the votes from all client unit users. The last one is a giving public display which acts as the main user interface masking the track list and their votes.Kaviani et al 13 propose new user interface concept that take advantage of the input and output capability of king-sized public display and mobile phone. They call this mode of interface as dual display, which allows users to execute multimedia user interfaces across both(prenominal) large and small display types. By shifting parts of a user interface down to a personal mobile device number of problems originating from limitations in large display real estate can be solved.
