    International Journal of Computer Sciences and Engineering Open Access Research Paper Vol.-6, Issue-12, Dec 2018 E-ISSN: 2347-2693 A Comparative Analysis of mobile Operating Systems Rina Dept of IT, GGDSD College, Chandigarh ,India *Corresponding Author: [email protected] Available online at: www.ijcseonline.org Accepted: 09/Dec/2018, Published: 31/Dec/2018 Abstract: The paper is based on the review of several research studies carried out on different mobile operating systems. A mobile operating system (or mobile OS) is an operating system for phones, tablets, smart watches, or other mobile devices which acts as an interface between users and mobiles. The use of mobile devices in our life is ever increasing. Nowadays everyone is using mobile phones from a lay man to businessmen to fulfill their basic requirements of life. We cannot even imagine our life without mobile phones. Therefore, it becomes very difficult for the mobile industries to provide best features and easy to use interface to its customer. Due to rapid advancement of the technology, the mobile industry is also continuously growing. The paper attempts to give a comparative study of operating systems used in mobile phones on the basis of their features, user interface and many more factors. Keywords: Mobile Operating system, iOS, Android, Smartphone, Windows. I. INTRUDUCTION concludes research work with future use of mobile technology. Mobile operating system is the interface between user and mobile phones to communicate and it provides many more II. HISTORY features which is essential to run mobile devices.

  • Pdas and Smartphones in the Classroom Teaching and Technology Trends Symposium March 30, 2007 Jimmy D
    PDAs and Smartphones in the Classroom Teaching and Technology Trends Symposium March 30, 2007 Jimmy D. Clark, Instructional Design Specialist Introduction Figure 1: Mobile Devices Today’s young learners use mobile devices such as cell phones, PDAs, MP3 players, and GPS devices every day. They enjoy learning as part of a group or team, or even in a “smartmob” or “learning swarm.” They play computer games, interact constantly with each other on websites such as Facebook and MySpace, and wish their college learning experience matched the learning they do in their everyday lives. Mobile learning technologies give them this opportunity. In this workshop we will focus on how PDAs and smartphones facilitate learning in today’s new teaching and learning environment. What You Will Learn in this Workshop In this workshop you will learn what mobile learning is: its history, some of the advantages of mobile learning, and about some of the tools used in mobile learning. You will also learn about the features of a PDA, its history, and the ways they are used in education. We will also talk about the challenges of using PDAs in education, with special emphasis on accessibility issues. In the last part of our discussion of PDAs we will talk about future trends in the use of PDAs in education. In the section on smartphones we will discuss what a smartphone is, its features, operating systems, the history of the smartphone, the reasons they are popular in education, and future trends in smartphones. This will not be a hands-on workshop. Goals and Objectives for this Workshop The goals and objectives for this workshop are: 1.

  • Senorita: a Chorded Keyboard for Sighted, Low Vision, and Blind
    Senorita: A Chorded Keyboard for Sighted, Low Vision, and Blind Mobile Users Gulnar Rakhmetulla Ahmed Sabbir Arif Human-Computer Interaction Group Human-Computer Interaction Group University of California, Merced University of California, Merced Merced, CA, United States Merced, CA, United States [email protected] [email protected] Figure 1. With Senorita, the left four keys are tapped with the left thumb and the right four keys are tapped with the right thumb. Tapping a key enters the letter in the top label. Tapping two keys simultaneously (chording) enters the common letter between the keys in the bottom label. The chord keys are arranged on opposite sides. Novices can tap a key to see the chords available for that key. This figure illustrates a novice user typing the word “we”. She scans the keyboard from the left and finds ‘w’ on the ‘I’ key. She taps on it with her left thumb to see all chords for that key on the other side, from the edge: ‘C’, ‘F’, ‘W’, and ‘X’ (the same letters in the bottom label of the ‘I’ key). She taps on ‘W’ with her right thumb to form a chord to enter the letter. The next letter ‘e’ is one of the most frequent letters in English, thus has a dedicated key. She taps on it with her left thumb to complete the word. ABSTRACT INTRODUCTION Senorita is a novel two-thumb virtual chorded keyboard for Virtual Qwerty augmented with linguistic and behavioral mod- mobile devices. It arranges the letters on eight keys in a single els has become the dominant input method for mobile devices.

  • Gesture Typing on Smartwatches Using a Segmented QWERTY Around the Bezel
    SwipeRing: Gesture Typing on Smartwatches Using a Segmented QWERTY Around the Bezel Gulnar Rakhmetulla* Ahmed Sabbir Arif† Human-Computer Interaction Group Human-Computer Interaction Group University of California, Merced University of California, Merced Figure 1: SwipeRing arranges the standard QWERTY layout around the edge of a smartwatch in seven zones. To enter a word, the user connects the zones containing the target letters by drawing gestures on the screen, like gesture typing on a virtual QWERTY. A statistical decoder interprets the input and enters the most probable word. A suggestion bar appears to display other possible words. The user could stroke right or left on the suggestion bar to see additional suggestions. Tapping on a suggestion replaces the last entered word. One-letter and out-of-vocabulary words are entered by repeated strokes from/to the zones containing the target letters, in which case the keyboard first enters the two one-letter words in the English language (see the second last image from the left), then the other letters in the sequence in which they appear in the zones (like multi-tap). Users could also repeatedly tap (instead of stroke) on the zones to enter the letters. The keyboard highlights the zones when the finger enters them and traces all finger movements. This figure illustrates the process of entering the phrase “the world is a stage” on the SwipeRing keyboard (upper sequence) and on a smartphone keyboard (bottom sequence). We can clearly see the resemblance of the gestures. ABSTRACT player or rejecting a phone call), checking notifications on incoming Most text entry techniques for smartwatches require repeated taps to text messages and social media posts, and using them as fitness enter one word, occupy most of the screen, or use layouts that are trackers to record daily physical activity.

  • Planet Computers and Jolla Launch Sailfish X for Gemini Pda
    PLANET COMPUTERS AND JOLLA LAUNCH SAILFISH X FOR GEMINI PDA • The official Sailfish X now available for Gemini PDA • Meet Planet Computers at MWC: Hall 7, stand 7K40 • Support Planet’s new Cosmo Communicator on Indiegogo: https://www.indiegogo.com/projects/cosmo-communicator#/ Mobile World Congress, Barcelona, 26th February 2019: Planet Computers and Jolla jointly announce the availability of the official version of Sailfish X for the Gemini PDA. Sailfish X is a downloadable version of Sailfish OS, the popular alternative mobile operating system. The Sailfish community offering is now extended to include a fully supported version of the Linux-based Sailfish OS for the Gemini PDA. The official Sailfish X software package features a suite of advanced functions, including seamless over-the-air (OTA) OS updates, Jolla Store access, end-user support, Microsoft Exchange support and, crucially for Gemini users, support for landscape user-interface (UI). The cost of Sailfish X for Gemini is €29.90 (incl. VAT) and it is currently available for customers within the EU, Norway & Switzerland. One of the most popular Indiegogo projects of 2017-2018, raising more than $2.5 million, Gemini re-imagines the PDA in a clamshell mobile device with a fully functioning physical keyboard and a large (5.99 inch) multi-touch colour display. Gemini enables users to type emails, blogs and social media posts easily on the go. Dr Janko Mrsic-Flogel, CEO of Planet Computers, comments: “The decision to offer Sailfish OS on the Gemini came about following strong demand from both the Gemini and Jolla communities. The Sailfish device family is joined by the Gemini PDA with its fully- integrated multi-lingual keyboard.
