The Museums Aotearoa Conference starts today in Palmerston North. And the theme of this year's event is accessibility. Bruce Roberts has been guiding tours for visually impaired people for more than 30 years. In his current job, he also helps blind people 'see' paintings at Te Papa. The museum has tours that are a combination of touch and audio description, for the visually impaired, the hearing impaired and for aphasic people, who find it difficult to communicate either through brain injury or stroke.
