The surface needs to be stable and static, preferably planar and not of skin color.
This would make the keyboard truly adaptable. The macro associated with each key can be varied easily from the frontend. After detection of the segment where the change occurs, a virtual key press would be initiated by calling a macro or a function using visual basic.The current function of each key would be displayed for user convenience and can be changed according to user preference. On running the program we would be able to detect any change in this image by comparing it with the original image stored. The proposed system would have an application frontend which would help initialise the keyboard to the new environment.Any image projected/surface can be a reference and a photo of the same is stored in memory as a reference image. The same functionality can be implemented using the Adaptable Virtual Keyboard and macros. This is done to increase interactivity but again, having a LCD display in every key makes is costly. Special hardware to project the “qwerty" layout and infrared light which is required in detection undermines the sole objective of reducing hardware components and cost reduction.Īnother hardware based keyboard named “Optimus Prime" has inbuilt LCD display on each key and the function of each key can be changed. The system uses 3D modelling to detect a keystroke and is processor intensive. Microsoft aimed at making the virtual keyboard but the layout and functions of the keyboard cannot be changed. The interactivity and usability of keyboards would surely increase if it could display a symbol for the current function associated with the key or if the language of the keyboard could be changed. As the name suggests the virtual keypad has no physical appearance.In the current scenario we use keyboards which have specific size and specific imprints on the keys. We are presenting here a next generation technology in this area, which is the Adaptable Virtual Keyboard. Thus we see that the new technology always has more benefits and is more user-friendly. These keypads give an elegant look, they give a better feel.They are dust-proof and has got much more life than the other keypads. Now-a-days soft touch keypads are much popular in the market. Few years before hard switches were used as keys. But there are parts of a computer system that are more susceptible to wear and tear.As the technology advances, more and more systems are introduced which will look after the user's comfort. In computer systems, the actual processors, are more likely to become outdated than to actually wear out. Characters “comma” and “period” are automatically derived from the current culture of the user interface.To design a multi functional and multi lingual image processing based adaptable keyboard.
The virtual keyboard in the screenshot does not change the presentation of the number value and retains the currency formatting. Developers can create custom keyboards of their own to enhance the app.
Touch UI activates its own virtual keyboard through the Universal Input when a numeric value or a telephone number is expected to be entered on a mobile device. Embedded Unified Keyboards for “number” and “tel” The native "number" input element in HTML forms will not allow that! Yet this input type is relied upon by web and hybrid app developers since it will activate the native numeric keyboard on a mobile device. The end users in many countries will expect to enter the "comma" character as the decimal separator. For example, the currency value of $1,234.56 must be entered in the form field as 1234.56. HTML 5 standard requires numbers to be presented visually as the sequence of 0-9 characters with the optional single decimal separator expressed as the "period" character. Form input controls make possible a comfortable and speedy text input on mobile devices. Hybrid mobile apps are built with HTML and JavaScript hosted in the native webview.
