Google Maps Navigation

Motorola Droid | Wednesday, December 14, 2011

In 2006, Google introduced a Java application called Google Maps for Mobile, intended to run on any Java-based phone or mobile device. Many of the web-based site's features are provided in the application.

On November 28, 2007, Google Maps for Mobile 2.0 was released. It introduced a GPS-like location service that does not require a GPS receiver. The "my location" feature works by utilizing the GPS location of the mobile device, if it is available. This information is supplemented by the software determining the nearest wireless networks and cell sites. The software then looks up the location of the cell site using a database of known wireless networks and cell sites. The Cell-site location method is used by triangulating the different signal strengths from different cell transmitters and then using their location property (retrieved from the online cell site database) to aid My Location in determining the user's current location. Wireless network location method is calculated by discovering the nearby WiFi hotspots and using their location property (retrieved from the online WiFi database, in the same way as the cell site database) to further discover the user's location. The order in which these take precedence is:

GPS-based services
WLAN-, WiFi-based services
Cell transmitter-based services

The software plots the streets in blue that are available with a yellow icon and a green circle around the estimated range of the cell site based on the transmitter's rated power (among other variables). The estimate is refined using the strength of the cell phone signal to estimate how close to the cell site the mobile device is.

hearing aid compatibility

Motorola Droid |

A hearing aid is an electroacoustic device which typically fits in or behind the wearer's ear, and is designed to amplify and modulate sound for the wearer. Earlier devices, known as "ear trumpets" or "ear horns", were passive funnel-like amplification cones designed to gather sound energy and direct it into the ear canal. Similar devices include the bone anchored hearing aid, and cochlear implant.

Motoblur (often stylized as MOTOBLUR) is an Android UI replacement and push-based service focused on social networking developed by Motorola. It aims at functional similarity to Palm's Synergy, including such features as Remote Wipe. Motoblur includes a variety of widgets which combine various social networking portals such as Facebook, MySpace, and Twitter as well as other services (news or weather reports) all in one place. Feeds and data are regularly pushed to these widgets. Motoblur is currently on Motorola's Atrix 4G, CLIQ/DEXT, Backflip, Devour, Flipout, Charm, Droid Pro, Flipside, DEFY, Bravo, Droid X, Droid 3, Droid 2, and Motorola Droid Bionic. The version found on the Droid X, Droid Pro, Droid 2 and DEFY is toned down and intended to be less intrusive than previous versions.

When first turned on, first generation Motoblur-based phones force a new user to create a Motoblur account, denying access to the main screen until the account is established. User account information is stored on Motorola's servers for access from web browsers and future phones. The newer devices allow users to defer Blur services for a later registration and has more filtering options and better battery management to optimize the Blur service experience.

In late 2010 Motorola announced that Motoblur will not be their focus for development in the future, as the latest Android builds are making custom skins largely redundant. While the Atrix, Droid 2 and Droid X do feature the UI skin, the new Droid RAZR does not feature Motoblur.

In 2011 PC World criticised Motoblur due to the poor performance of the interface.

OMAP

Motorola Droid |

OMAP developed by Texas Instruments is a category of proprietary system on chips (SoCs) for portable and mobile multimedia applications. OMAP devices generally include a general-purpose ARM architecture processor core plus one or more specialized co-processors. Earlier OMAP variants commonly featured a variant of the Texas Instruments TMS320 series digital signal processor.

QWERTY

Motorola Droid |

QWERTY is the most common modern-day keyboard layout. The name comes from the first six letters (keys) appearing in the topleft letter row of the keyboard, read left to right: Q-W-E-R-T-Y. The QWERTY design is based on a layout created for the Sholes and Glidden typewriter and sold to Remington in the same year, when it first appeared in typewriters. It became popular with the success of the Remington No. 2 of 1878, and remains in use on electronic keyboards due to the network effect of a standard layout and a belief that alternatives fail to provide very significant advantages. The use and adoption of the QWERTY keyboard is often viewed as one of the most important case studies in open standards because of the widespread, collective adoption and use of the product, particularly in the United States.

sliding

Motorola Droid |

A slider or slide phone is composed of usually two, but sometimes more, sections that slide past each other on rails. Most slider phones have a display segment which houses the speaker used for calls and the phone's screen, while another segment contains the keypad or keyboard and slides out for use. The goal of using a sliding form factor is to allow the operator to take advantage of full physical keyboards or keypads, without sacrificing portability, by "retracting" them into the phone when these are not in use.

The Siemens SL10 was one of the first sliding mobile phones in 1999. Some phones have an automatic slider built in which deploys the keypad. Many phones will "pop out" their keypad segments as soon as the user begins to slide the phone apart. Unique models are the 2-way slider (sliding up or down provides distinct functions) such as the Nokia N85 or Nokia N95.

A version of the slider form factor, the side slider or QWERTY slider, uses vertical access of the keyboard on the bottom segment. The side slider form factor is primarily used to facilitate faster access to the keyboard with both thumbs. The Danger Hiptop and the Sony Mylo are two primary examples.

Google Maps

Google, Motorola Droid |

Google Maps (formerly Google Local) is a web mapping service application and technology provided by Google, free (for non-commercial use), that powers many map-based services, including the Google Maps website, Google Ride Finder, Google Transit, and maps embedded on third-party websites via the Google Maps API. It offers street maps, a route planner for traveling by foot, car, bike (beta) or public transport and an urban business locator for numerous countries around the world. Google Maps satellite images are not updated in real time; they are several months or years old.

Google Maps uses a close variant of the Mercator projection, so it cannot show areas around the poles. A related product is Google Earth, a stand-alone program which offers more globe-viewing features, including showing polar areas.
