Product developer for deaf, blind and both blind and deaf for the past 20 years. Signtel has also been developing with the Laboratory for Advanced Studies, products in other fields, such as robotics (e.g., "Robots with Human Conscience and Empathy") and its paradigm-shift technology for combating climate change. Artificial Intelligence has been part of many of the developments. Many patents have been awarded and many others are still pending. Some of the products for the blind and deaf individuals benefited from Signtel's over 100 deaf or blind Assistant developers employees where their life experience mandated the needed technologies.
