Is It Possible to Innovate the Interface of a Simple Calculator?

A simple question that immediately responds: “No, we do not need it.” If it is possible, however, is quite another matter. Really, it is an interesting challenge changing the interface of the calculator in a way that can attract and impress the user of perhaps one of the most widely used and useful software in an operational environment. Over the years, the calculator’s user interface has remained simple and repetitive although the mechanisms of interaction have changed so much.

The only thing a user wants in a calculator is to find the numbers which should be arranged on a grid of buttons and the display to make it perform its function: a calculation!

It was with this exact scenario in mind that birthed the idea for the CalcSphere Project. It has an extremely intuitive interface which is completely different from that of a traditional calculator. This small application can also store up to five operations group. It is also dynamic and customizable by allowing you to select up to three different themes for viewing.

The CalcSphere Project proposal is just to promote a new way to perform calculations without numbers arranged in a grid of rows and columns ready to be clicked or touched. A different way of doing the same thing: a simple calculator!

Based on a Java ME application, CalcSphere is designed to be used only on devices with touch screens, and its free version will be dependent on internet connection because it makes use of the In-App Advertising API. In this first version, CalcSphere is only compatible with some low cost smartphones in the Nokia S40 line.

The free version of CalcSphere can be found at the Nokia Store's link below: http://store.nokia.com/content/313798

The interesting point here is that we have an application based on Java ME which was inspired by the simple calculator, however, it has a completely new interface that uses common resources like the touch screen and on-line advertising while still working on low cost devices. Long live Java ME!
