Navigation assistance services for people with visual impairment pose the challenge of providing accurate guidance through non-visual navigation instructions. This paper proposes two techniques to guide user during assistance, and in particular turns straight paths. Both adopt a combination speech non-speech audio aim continuous, accurate, unobtrusive guidance. The solutions differ sonification technique used generate audio. were evaluated real-world environment nine participants having severe impairment. Experimental results show that one proposed is significantly more effective than baseline approach adopted existing solutions, terms accuracy Thus, it practical solution problem
