One of the most common electronic devices available in homes around the world is the TV. Its high utilization rate in domestic environments opens a series of possibilities to meet the most varied needs of its viewers. In this context, projects developed for specific audiences can take advantage of the opportunities offered by TV. +TV4E is a solution designed for the elderly, which aims to provide their inclusion by displaying informative contents on topics of their interest. Applications such as this are very relevant because they directly affect a considerable portion of the world’s population. However, many of the features available in applications such as the +TV4E are inaccessible to people with physical disabilities since the main features available must be accessed through conventional remotes. New forms of interaction, based on the principles of Assistive Technology (AT), aim to enable people with physical disabilities to perform daily tasks in a more autonomous way. An example of an AT-based initiative is the IOM (Mouse-Eye Interface) project, which focuses on developing a device that functions as an alternative form of computer interaction, designed for people with motor disabilities in the upper limbs. In this context, this paper introduces IOM4TV, a software prototype that allows its users to control the +TV4E application through the IOM device. The article presents the proposed architecture, highlighting the main steps involved during the development of the solution. The paper also highlights the results obtained with the first round of prototype testing using two evaluation tools: SAM and AttrakDiff.
