I have read many publications about auditory and haptic feedback for supporting obstacle detection, and object identification to visually impaired.
Regarding auditory feedback, there is new a problem introduced by technology called "Masking", that is the difficulty of the visually impaired in listening the environment given he/she has to pay attention to the auditory feedback. Also, usually auditory feedback takes too much time to be learned. Once it is learned, one has to interpret each feedback regarding the current environment and the response time has been too high for using in real conditions.
Regarding tactile feedback, there is the problem of resolution of the hardware (skin actuators, usually matrices of vibe motors) which is not high enough to depict many real case situations. Besides the hardware resolution, there is the difference of sensibility each part of the body has and the fact that many visually impaired are also diabetic, which usually affects the sensitivity of the skin on the limbs...
I did not see your entire question for some reason, but you may wish to know that I express my views on the best application (strengths, weaknesses, and optimal use) of each sensory system for conveying self-motion and/or looming, and I think that paper may be relevant to your interesting question.
The paper is:
Lawson, B. D. (2014). Tactile Displays for Cueing Self-Motion and Looming: What Would Gibson Think?. Advances in Cognitive Engineering and Neuroergonomics, 11, 3.
[...but it is not only about tactile displays]
Access options include:
1) Check on my ResearchGate to see if it is there;
2) Open my Recent Publications list on ResGate to get my email and I will send it to you that way once you email me.
3) Try looking inside a google book...

4) I don't usually mess w/ ResearchGate that much at work, so sending it to your privately via ResGate should be the last option.
Hope this helps!
Hi, Ben! Thank you very much for your paper. I already downloaded it using the proxy of my university. I also published the results from my research in a paper at UbiComp'15.
You may find the article here: http://dl.acm.org/ft_gateway.cfm?id=2807541&ftid=1619214&dwn=1&CFID=547303467&CFTOKEN=31965478
Or I can send it to you (just drop me a line at [email protected]).
Thank you very much!
