Its quite amazing how gadgets continue to evolve these days. Before, watches are only used for letting people know the current time. Later, it evolved into alarms and stop watches. Today, watches have already evolved into high end gadgets. They are already multi-purpose. Take for example GPS watches. These watches do not only provide people with regards to what time is it already, but also helps people calculate the distance they have traveled.

GPS watches use the latest technology called Global Positioning System. GPS calculates the exact position and timing of a subject. This is also the same system used by the military to locate the position of a person. Often, GPS watches are also categorized as sports watches. This is because these watches are being used by sports enthusiasts and athletes in measuring the distance that they have traveled. For instance, bikers would calculate if how long have they already traveled from one point to another.

People who also use to jog are using GPS watches. Often, these GPS watches also come along with a Heart Rate Monitor. Individuals who use these GPS watches with Heart Rate Monitors (HRM) find them very useful in calculating the distance they travel as well as checking their vitals. Aside from calculating distance, GPS watches are also being used by parents who want to keep track of their childrens location. They let their children wear a GPS watch and then keep track of their whereabouts with the use of a tracking device.

It is really amazing how technology keeps on discovering new and enhanced gadgets. Aside from GPS watches, there are also watches that have built in radios, flashlights, lighters, calendars, calculators, chronographs, altimeters, remote controls, and even communication devices. With the constant innovation in technology, expect more amazing gadgets to come that can provide individuals with almost everything they want to know or monitor.

A recent UK TV advertising campaign suggests that Sony Ericsson has high hopes for it new handset, the Vivaz. If the spec list is anything to go by, it certainly looks set to be popular. Its key features include touch screen navigation, an 8.1 mega pixel camera with the ability to shoot HD video, and Wi-Fi internet access.

The Vivaz utilises both vibration and ringing to alert users to incoming calls and messages, with the option to assign MO3 music files as ringtones. This allows users to customise their phones so they can hear whatever song they like when the phone rings. In order to achieve handsfree communication, both a speakerphone system and an audio jack are included, the latter of which accommodates both earphones for listening to music, and handsfree headsets.

An array of features is included as standard, which accomplish a range of everyday tasks. A versatile media player supports most common formats of both music and video files, such as MP3 and MP4. Alongside this, a stereo FM radio player is included, as is a selection of pre-installed games along with access to a library of additional downloadable games. Social networking fans are well catered for with Facebook and Twitter apps which offer a convenient method of directly accessing these sites. YouTube and Picasa integration is an impressive feature which allows photos and video s taken on the phone’s camera to be directly uploaded to these sites in seconds for the world to enjoy.

The Vivaz relies on touch screen technology for navigation of the Symbian Series 60 user interface. The 3.2 inch TFT resistive touch screen displays up to 16M colours within a pixel layout of 360×640 for high quality display of on screen content, offering great levels of detail and clarity. An accelerometer sensor is built into the screen for auto-rotate of the on screen content, so it can be viewed in both portrait and landscape forms. Another interesting feature of the screen is an accurate handwriting recognition tool.

Internal memory within the Vivaz is 75 MG as standard, which offers a good deal of storage for data such as music tracks, video clips or photos. A micro SD card slot is also provided for the same purpose, with a pre-installed 8 GB card. This can be upgraded, however, by installing a card of up to 16 GB in the card slot. This would provide enough storage for most people’s needs. The internal phonebook features the popular photocall function. This allows users to assign a photo to each contact. This is in turn displayed on the screen whenever that person calls or is called.

As mentioned, a powerful 8 mega pixel camera is included, which offers extremely high quality photos along with the ability to shoot gorgeous HD video. A TV out port means the phone can be plugged into a compatible HD TV so High Definition can be enjoyed in all its glory.

Both 3G and Wi-Fi provide fast internet connections dependent upon location, and class 10 versions of both EDGE and GPRS keep the Vivaz connected to cellular networks.

With such impressive hardware as well as software, it would be surprising if this exciting new handset was anything less of a hit for the manufacturer.
