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

Many of the research presented in the field of energetic knell-based interaction techniques that have been developed so far f whole into terzetto main classes according to Sas & Dix 21. In somewhat research, the personal doojigger effectively acts as an extended input device for text editing or pointing task. In others, the phone is used to upload and download media using banal content and protocols. The third class is where the mobile phone is a to a greater extent integral part of the interaction, typically using the display of the device in concert with the universe display. Ballagas et al 7 present a survey of the existed interaction techniques that use mobile phones as pointing device. Alongside with the survey, they present an analysis on these techniques based on the following taxonomy position, orient, recognize, path, quantify, and text .The study concludes that the mobile phone is suitable mull for positioning tasks in various ways peculiarly when interacting wi th normal 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 image treat and visual recognition as a base in at that place interaction technique, since that most of the smart phones and handheld devices are equipped 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 canonical 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 building blocks the Symbian client covering running on the mobile phone. The role of this unit is to enable drug users to select a skip over from the presented list on t he phone screen. The second unit is the server application running on a PC which counts the votes from all client unit users. The last one is a oversize public display which acts as the main user interface showing the track list and their votes.Kaviani et al 13 propose new user interface construct that take advantage of the input and output capability of large public display and mobile phone. They call this mode of interface as double display, which allows users to execute multimedia user interfaces across both large and small display types. By shifting parts of a user interface down to a personal mobile device depend of problems originating from limitations in large display real estate can be solved.
