After a successful acquisition in August 2005, InSiPhil Singapore continues to bring Telesensory's range of electronic and computer-based products to people with low vision all over the world. For nearly 40 years, Telesensory products have been helping the visually impaired and blind achieve greater independence through innovative, technology-based products. The management and its team at InSiPhil are dedicated to continue this legacy, providing superior products and continually exceeding customer expectations.

InSiPhil is an international group of companies extending to North America, Latin America, Europe (UK) , Japan, and the Middle East. The corporate office in Singapore includes the company's product development, sales and marketing departments. All Telesensory products are produced at Telesensory Manufacturing in Senai, Johor, Malaysia and Telesensory Services and Repair is located at Bakersfield, California, USA. Through a wide network of companies and distributors, Telesensory products are available in 50 countries worldwide. In the United States, products are sold by more than 100 distributors, dealers, and resellers who provide personalized customer support throughout the country.

More than four million people in the United States, over eleven million in the European Economic Community, and many more worldwide, are visually impaired to the point where eyeglasses are not sufficient to enable them to meet a large portion of their visual needs. Many are seniors whose eyesight has begun to diminish due to macular degeneration. The number of seniors -people over 65- increased by 22 percent between 1980 and 1990, to about 13 percent of the population in North America. The number of people who could potentially benefit from Telesensory's low vision products is expected to continue to increase as America's population ages.

Telesensory was born out of the desire to help a blind girl read. In 1970, four members of the prestigious American Stanford University electrical engineering department led by Professor John Linvill developed the technology that was to become the Optacon, a portable electronic print-reading device, the company's first product, in an effort to assist Professor Linvill's vision impaired daughter.

Today, Telesensory is the legacy of a number of pioneers in the adaptive devices industry, starting with Telesensory itself, Visualtek and Apollo Lasers in the early 1970s, and Kurzweil Computer Products in 1975. In the 1980s, Telesensory began to focus on providing devices for the low vision population to meet the needs of the aging American population. Continuous research and development has created the industry's 1st transportable unit, the Vertex in 2007, as well as other product improvements such as Apex Pro and Vertex Pro.
