Dear Hale, Thank You for information. I am Irina Sumarokova from Russia. I am a ICEVI member for 8 years. I am blind. Because of this I need mobility assistance for the conference. I want to registrate for VIII ICEVI conference. But I did not understand about sighted guide. What does it mean? Is it a guide for excursion tour or the mobility assistance for the blind for the conference? Please tell me about it. Best wishes, Irina Sumarokova
