Which company is exploring language learning through feel, allowing the deaf to hear through their skin?

The correct answer is Facebook. The company has been actively involved in exploring innovative approaches to communication and language learning, particularly through the use of technology that accommodates diverse needs. Notably, Facebook's research initiatives have considered methods to help individuals who are deaf or hard of hearing by enabling them to perceive sound through tactile sensations on their skin.

This aligns with the company’s broader mission to enhance connectivity and communication among users, regardless of their sensory abilities. The exploration of technology that allows deaf individuals to experience sound in a different manner exemplifies a commitment to inclusivity and the use of emerging technologies to break barriers.

Other companies mentioned, while also engaged in innovative research and technology development, have not specifically focused on this unique approach to language learning for the deaf community.
