Accommodate the expression of local units of measure, such as dates, times, money, etc. This "personalizes" the screen for the user. Headings - screen headings should be placed in a standard position for easy identification by the user. One good example of this is to have the user enter a Zip Code first, which should then automatically populate City and State entries. For example, automatically upshift or downshift characters - this is particularly useful when entering State Postal Codes (upshift), and entering e-mail addresses (downshift). Check characters entered and automatically adjust accordingly. Armed with this knowledge, the developer then determines the most suitable mechanisms for collecting the data; for GUI windows, this primarily includes such things as field entries, radio buttons, check boxes, selection lists, and text boxes. If a generated value is displayed, explain how it is computed (from other field entries). Generated data - quite often it is necessary to show computations based on primary values being inputted by the user.
The objective here is to force the user to make correct entries as easily as possible. Make active use of selection lists, thereby forcing the user to select a choice from a prescribed list as opposed to typing an entry. Make yourself familiar with common machine learning algorithms, like linear regression, logistic regression, decision tree, random forest, naive bayes, k-nearest neighbour, and support vector machines. Too often I have seen screens with little support in this regards. The Playscript language technique for writing procedures is particularly useful in this regards (see "References" below for details). 53. Update all of your drivers in Windows, including chipset and motherboard drivers to their latest versions. Validation Rules - the specific values which the data element may assume, including default values. There may be many reasons why you wish to browse privately. Length - the maximum number of characters which may be assigned to a data element.
