Tablet Pc Innovation

  1. 1. Tablet PC Innovation ❧ ❧ Mohd Shaffi Bin Mahadi A124280
  2. 2. Definition• A tablet computer, or a tablet, is a mobile computer, larger than a mobile phone or personal digital assistant, integrated into a flat touch screen and primarily operated by touching the screen rather than using a physical keyboard. It often uses an onscreen virtual keyboard, a passive stylus pen, or a digital pen
  3. 3. Types of Tablet PC• Traditional tablet PCs - A tablet personal computer (tablet PC) is a portable personal computer equipped with a touchscreen as a primary input device, and running a modified desktop OS designed to be operated and owned by an individual• Post-PC Tablets – A new tablet computers that have been introduced with mobile operating systems which have a different interface instead of the traditional desktop OS, and represent a new type of computing device
  4. 4. Touch User Interface Handwriting Recognition•Because tablet personal computers normally use a stylus,they quite often implement handwriting recognition.•Tablet computers with finger driven screens do not havethis feature.•Finger driven screens however are potentially better suitedfor inputting "variable width stroke based" characters, likeChinese/Japanese/Korean writing, due to their built incapability of "pressure sensing".
  5. 5. Types of Touchscreen Hardware A- Resistive touchscreens -•Passive and can respond to any kind of pressure on thescreen.•They allow a high level of precision but may requirecalibration to be accurate.•A stylus or fingernail is often used for resistive screens.•this technology has faded out on high-end devices where ithas been replaced by capacitive touchscreens.
  6. 6. Types of Touchscreen Hardware B- Capacitive touchscreens•Tend to be less accurate, but more responsive thanresistive screens.•Because they require a conductive material, such as afinger tip, for input, they are not common among (stylususing) Tablet PCs•More prominent on the smaller scale "tablet computer"devices for ease of use, which generally do not use astylus, and need multi-touch capabilities.
  7. 7. Other Touchscreen Hardware Technology• Palm recognition - It prevents inadvertent palms or other contacts from disrupting the pens input.• Multi-touch capabilities, which can recognize multiple simultaneous finger touches, allowing for enhanced manipulation of on-screen objects.• Pressure sensitive films - allow pressure sensitivity such as those on graphics tablets.
  8. 8. Other Features in Tablet PC• Accelerometer: An accelerometer is a device that detects the physical movements of the tablet. This allows greater flexibility of use since tablets do not necessarily have a fixed direction of use. The accelerometer can also be used to detect the orientation of the tablet relative to the center of the earth, but can also detect movement of the tablet, both of which can be used as an alternative control interface for a tablets software.Ambient light and proximity sensors are additional "senses", that can provide controlling input for the tablet.• Storage drive: Large tablets use storage drives similar to laptops, while smaller ones tend to use drives similar to MP3 players or have on-board flash memory. They also often have ports for removable storage such as Secure Digital cards. Due to the nature of the use of tablets, solid-state memory is
  9. 9. Other Features in Tablet PC• Wireless: Because tablets by design are mobile computers, wireless connections are less restrictive to motion than wired connections. Wi-Fi connectivity has become ubiquitous among tablets. Bluetooth is commonly used for connecting peripherals and communicating with local devices in place of a wired USB connection.• 3D: Following mobile phone, there are also 3D slate tablet with dual lens at the back of the tablet and also provided with blue-red glasses.• Docking station: Some newer tablets are offering a optional docking station that has a full size qwerty keyboard and USB port, providing both portability and flexibility
