The index has returned a historic annualized average return of around 11.88 since. stock market overall, dating back to the 1920s. These values can be applied for the implementation and design of future Graphical User Interfaces (GUI) for mobile devices. The index acts as a benchmark of the performance of the U.S. The results show a division of the interdependence in two parts, based on the difficulty of the input task they define threshold values for accuracy of user input. This index can take the form of a financial indication, such as a company's earnings or liquidity. Many companies use key performance indexes to compare their results to others in the same industry or business sector. Subsequent regression analyses allow quantitative estimation of these effects. A key performance index is useful in determining an organisation's operational, financial and strategic accomplishments. Results show a significant increase of the error rate and a significant decrease of the index of performance for increased walking speed. In an experiment with n=18 participants, the general indices of performance (bits per second) were measured while standing and walking with constant speed (2, 3.5, 5 km/h).

The way in which Fitts’ law can enhance the analysis is explained. A company will be classified as large, mid or small cap based primarily on its market capitalization. For the analysis of the interdependence, appropriate performance measures, for example, subjective workload ratings or error rate, have to be applied. Our suite of large, mid and small cap indexes is designed to accurately represent and measure global equity markets as they evolve, meeting a wide range of changing investor needs within a single framework. This chapter describes the interdependence between locomotion while walking and human input performance in mobile Human-Computer-Interaction (HCI).
