The VHIT is an instrumented bedside technique used to diagnose reduction in vestibular function in one ear vs. the other. As of 11/2019 we had done 3000+ VHIT tests at Chicago Dizziness and Hearing, and we have run into technical issues. Although we have both of the most common types of VHIT devices, we almost only use the Interacoustic version (i.e. German version).
Martinez et al (2018) wrote a paper on HITCal: A software tool for analysis of video head impulse test responses. This paper discusses a Matlab program that was developed to read exports from the VHIT software. Their program processes the xml output. It states that it is "open access", and presumably others can use it as well. I have not tried to use this.
I myself have processed the csv format export from the VHIT software, using "R". This is fairly simple and is not worth a paper.
