The T-Mobile Tap is a mobile phone manufactured by Huawei , Inc. and marketed under the T-Mobile brand and service. It is also known as the Huawei U7519 . It was released in November 2009, and was available in many European and Asian markets.
9-533: The Tap features a 2.8-inch resistive touchscreen . It also features a 2.0 megapixel camera, Bluetooth connectivity, built-in GPS , a music player, and access to T-Mobile's MyFaves. While it lacks a 3.5 mm headset jack, the device instead comes with an in-ear headset that connects through the Tap's USB port. The phone is also bundled with a USB cable to manage files on a personal computer, Huawei's PC Suite software to manage
18-429: A stylus will generally offer greater pointing precision than a capacitive touchscreen operated with a finger. Costs are relatively low when compared with active touchscreen technologies, but are also more prone to damage. Resistive touchscreen technology can be made to support multi-touch input. Single-touch screens register multiple touch inputs in their balanced location and pressure levels. For people who must grip
27-470: Is called matrix , in which striped electrodes on substrates such as glass or plastic face each other. The second type is called analogue which consists of transparent electrodes without any patterning facing each other. As of 2011 analogue offered lowered production costs. When contact is made to the surface of the touchscreen, the two sheets are pressed together. On these two sheets there are horizontal and vertical lines that, when pushed together, register
36-586: The active portion of the screen or must set their entire hand down on the screen, alternative touchscreen technologies are available, such as an active touchscreen in which only the stylus creates input and skin touches are rejected. However, newer touchscreen technologies allow the use of multi-touch without the aforementioned vectoring issues. Where conditions allow bare finger operation, the resistive screen's poorer responsiveness to light touches has caused it to generally be considered for use with low resolution screens and to lose market share to capacitive screens in
45-528: The colors midnight blue and berry (metallic pink). It cannot be used without a SIM card. This mobile phone related article is a stub . You can help Misplaced Pages by expanding it . Resistive touchscreen A resistive touchscreen is a type of touch-sensitive display that works by detecting pressure applied to the screen. It is composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. There are two different types of metallic layers. The first type
54-467: The files, and a T-Mobile full size SIM card . A spring-loading microSD slot is located under the phone's battery cover. Physical buttons are the power button, a lock button and camera launcher on the side of the phone, a call start button, a navigation pad and 'wheel', and a call end button. The physical specifications of this phone are comparable with that of the HTC Touch . The phone currently comes in
63-404: The precise location of the touch. Because the touchscreen senses input from contact with nearly any object (finger, stylus/pen, palm) resistive touchscreens are a type of "passive" technology. For example, during the operation of a four-wire touchscreen, a uniform, unidirectional voltage gradient is applied to the first sheet. When the two sheets are pressed together, the second sheet measures
72-550: The touchscreen responds to pressure on its surface, contact can be made with a finger or any other pointing device. Resistive touchscreen technology works well with almost any stylus -like object, and can also be operated with gloved fingers and bare fingers alike. In some circumstances, this is more desirable than a capacitive touchscreen, which needs a capacitive pointer, such as a bare finger (though some capacitive sensors can detect gloves and some gloves can work with all capacitive screens). A resistive touchscreen operated with
81-517: The voltage as distance along with the first sheet, providing the X coordinate. When this contact coordinate has been acquired, the voltage gradient is applied to the second sheet to ascertain the Y coordinate. These operations occur within a few milliseconds, registering the exact touch location as contact is made, provided the screen has been properly calibrated for variations in resistivity. Resistive touchscreens can have high resolution (4096 x 4096 or higher), providing accurate touch control. Because
