Facilitating Mechanical Design with Augmented Reality

By enhancing a real scene with computer generated objects, Augmented Reality (AR), has proven itself as a valuable Human-Computer Interface (HCI) in numerous application areas such as medical, military, entertainment and manufacturing. It enables higher performance of on-site tasks with seamless presentation of up-to-date, task-related information to the users during the operation. AR has potentials in design because the current interface provided by Computer-aided Design (CAD) packages is less intuitive and reports show that the presence of physical objects help design thinking and communication. This research explores the use of AR to improve the efficiency of a design process, specifically in mechanical design.

Whither Japan's Economy?

The Japanese economy entered a long recession in spring 1997. Its economic growth has been much lower than in the US and the EU despite large fiscal stimulus packages, a monetary policy which has brought interest rates to zero since 1999, injections of public money to recapitalize banks, and programs of liberalization and deregulation. How could all these policies have failed to bring the Japanese economy back on a sustainable growth path? This paper argues that the failure of Japan's efforts to restore a sound economic environment is the result of having deliberately chosen inappropriate and inadequate monetary and fiscal instruments to tackle the macroeconomic and structural problems that have burdened the Japanese economy since the burst of the financial bubble at the beginning of the 90s. These choices were deliberate, since the "right" policies (in primis the resolution of the banking crisis) presented unbearable political costs, not only for the ruling parties, but also for the bureaucratic and business elites. The misfortunes of the Japanese economy during the long recession not only allow us to draw important economic policy lessons, but also stimulate reflections on the disruptive role on economic policies caused by powerful vested interests when an economy needs broad and deep structural changes. The final part of the paper focuses on ways to tackle Japan's banking crisis. In particular, it explores the Scandinavian solution, which, mutatis mutandis, might serve Japanese policy-makers well.
