I. Introduction
In the course of the next years, worldwide population will constantly increase its average life expectancy. We can expect elderly forming a large part of the population as we can witness in some countries. Elders have special needs given the fact that the aging process will come with a considerable decline in capabilities making them prone to falls, forget things, and others. As technology advances so do the opportunities to come up with new tools that can drastically improve the lifestyle of our elders. Along with the particular requirements in assisting the elders, we must think in how they will interact with the tools and how to take advantage of the solutions available today so our contributions can be applied in the short term.
