Cualquiera que sepa que las microempresas en Medellín, actualmente suman cerca de 95.000 -algo así como el 96% del tejido empresarial-, y que generan alrededor del 50% del empleo de la ciudad, le interesará este libro. La razón es simple: en él se ofrecen modos muy concretos, no sólo de conservarlas sino de fortalecerlas. Haga el lector el siguiente ejercicio: cierre los ojos e imagine qué le ocurriría a la ciudad y a miles de sus familias si por algún albur, todas -o la mayoría- de las microempresas desaparecieran de repente. Seguramente lo que vería, no sería agradable, entonces abra los ojos y dispóngase a leer esta obra.

This book presents cutting-edge research on innovative system interfaces, highlighting both lifecycle development and human–technology interaction, especially in virtual, augmented and mixed reality systems. It describes advanced methodologies and tools for evaluating and improving interface usability, and discusses new models, case studies and good practices. The book addresses the human, hardware, and software factors in the process of developing interfaces for optimizing total system performance, while minimizing costs. It also highlights the forces currently shaping the nature of computing and systems, such as the importance of portability and technologies for reducing power requirements; the need for better assimilation of computation in the environment; and solutions to promote computer and system accessibility for people with special needs. Based on the AHFE 2020 Virtual Conference on Human Factors and Systems Interaction, held on July 16–20, 2020, the book offers a timely survey and a practice-oriented guide for systems interface users and developers alike.
