You can significantly improve convenience and user efficiency by making inexpensive changes throughout your house, and I'm not referring to automation of the whole house, even though you could take a baby step developing a "smart home" simply by spending a little more for motion-activated switches or automated deadbolts and thermostats. All of what I'm describing can be purchased on-line or at the home improvement retailers.
But even if you don't want to go high-tech, boost the convenience of your home simply by swapping out round door knobs and traditional light switches. Every area in the house should have these universally designed basics promoting convenience . Each is simple and intuitive to use by the most people, whether standing or seated, with low probability for error and includes multiple ways of accomplishing the same goal.
