Andalib products are designed to be distinctive and intuitive. This is a challenging task involving a balance between new design ideas and potential of user confusion. The Organizer product contained an innovative method for selecting the date to view; we call it the Date Slider. It is a combination of 3 selectors, a selector being a control designed to allow the user to pick or select. Combobox, dropdowns, tab controls and radio buttons are all selectors. When choosing a selector you need to decide if the values are fixed or infinite, the numbers of values to pick from, the importance of the value, and how quickly you want to change the value. Combobox has a dropdown with a list of fixed values plus it lets you type in a new value, which makes it a good option for lists of infinite values with a few commonly used values. Tab controls and radio buttons present every choice at the top level, which make them good for important values that need to be quick to access. In the case of the Date Slider the value is important and the range of values is fairly limited. Plus the values have an inherent order, January precedes February. We came up with the idea of presenting them group into year, month and day in vertical sliders. It provided a very distinctive design element without much confusion. What do you think? Did we make the right call? Do you like it?
