Ologic built this Bug Droid robot for Google I/O 2011. It communicates with an Android Nexus S 4G phone via bluetooth. The Android phone control app was written in the drag-and-drop App Inventor. Android News, Android Video, Android Idea, Android Developer

ABSTRACT We describe the early development of an experimental outdoor mobile augmented reality (AR) application, AR street view,‖ running on a Google Android Dev Phone 1. This project addresses the design of interaction and visualization techniques for AR user interfaces on mobile phones. Our experience suggests that usabili-ty is compromised by a variety of issues, including tracking and registration errors caused by the relatively inaccurate GPS and orientation sensor, the need to hold the phone away from the body in potentially awkward poses, and the relatively small field of view covered by the display and camera.

  This journal describes how to use wireless connected ad hock who helped in the search for victims of natural disasters ( case study ) ABSTRACT In search and rescue scenarios local information on victims and other finds needs to be disseminated rapidly to other rescue workers and team leaders. However, post disaster scenarios may imply the collapse of information infrastructure including cellular communication and Internet connectivity. Even if we consider wireless ad hoc communication as a means of information dissemination we should count on frequent loss of connectivity in the network due to unpredictable mobility and sparse network topologies. In this paper we present the realization of an existing manycast protocol (random walk gossip) on commodity handheld devices running the Android platform. This communication mode is used to demonstrate the potential for distributed information dissemination on victims and finds. The application layer is an adaptation o...

For friends   who like   it might website android   design   is beneficial to   all of you. Android Pattern   this site   helps   us   understand the   pattern   of   android application .   for example if   to   make   navigation on the   android   we   must   consider the   good and   the bad   from   the user side . Thus we   can   make   a good application   and easy to   navigate   by the user .   Android does not just   have   a good   core   but   also   should   have   a nice design   too . [Read More]

Android is a popular mobile-device platform developed by Google. Android’s application model is designed to encourage applications to share their code and data with other applications. While such sharing can be tightly controlled with permissions, in general users cannot determine what applications will do with their data, and thereby cannot decide what permissions such applications should run with. In this paper we present SC AN D ROID, a tool for reasoning automatically about the security of Android applications. SC AN D ROID’s analysis is modular to allow incremental checking of applications as they are installed on an Android device.

Communicate anywhere, any time … without infrastructure, without mobile towers, without satellites, without wifi hotspots, and without carriers. Use existing off-the-shelf mobile cell phone handsets. Use your existing mobile phone number wherever you go, and never pay roaming charges again. Communications should not just be for the fortunate — communication should be freely available to everyone, because we believe communication should be a human right. Serval enables mobile communications no matter what your circumstance: mobile communications in the face of disaster, in the face of poverty, in the face of isolation, in the face of civil unrest, or in the face of network black-spots. In short, Serval provides resilient mobile communications for all people, anywhere in the universe. Serval technology bridges the digital divide. We have proved that it is possible, using open source technology to create a mobile communications platform that benefits everyone, for all tim...

Desperately in need of a graduation paper, [Andrei] decided to build a few computer controlled recon vehicles (PDF warning) , and we’re really impressed with the minimalist approach [Andrei] took. The Computer Operated Recon Entity (C.O.R.E.) mk. I is based around a laptop. Instead of an Arduino, [Andrei] used a car stereo amp to control the motors. The two channel amp [Andrei] picked out has four outputs. Tying a motor to each output gives a four-wheel drive robot that’s really clever in its simplicity. With an onboard webcam, [Andrei] can do live video streaming from his remote vehicle. Outputting a specific tone with the sound card allows for full control of the robot. The C.O.R.E. mk. II uses a Samsung Galaxy I5500 phone – the cheapest Android phone [Andrei] could find. The setup is similar to the mk. I C.O.R.E. with a WiFi connection sending video back to a base station. Control of the two motors is still handled by playing sound files and sending that to a stereo amp connec...
