Otis – the virtual patient simulates a range of complex hearing defects so that correct audiometry can be administered without having to burden a patient at all. The software intelligently and realistically simulates the behaviour of the patient and detects possible user errors immediately. The program guides the learner through the exercises at several levels of difficulty and provides useful help.

Optimizing Education

Otis shortens the time needed for training, as all types of hearing impairment can be simulated for audiometry testing at any time. In this way, proficiency in procedures can be improved, and the skills acquired can be put into practice significantly faster.

Using the program, experienced practitioners also have the opportunity to acquire routine in working with complex hearing impairments, thus decisively increasing client safety. The integration of autonomous learning concepts allows learners to work simply and efficiently wherever they are, and thus make best use of their time.

Developed by Experts

Otis – the virtual patient was developed in close cooperation with consultants at the University Hospital in Zurich, the Academy for Hearing Aid Acoustics in Lubeck and the Aston University in Birmingham. Otis does not just set completely new quality standards; it has also been extremely well received by experts. Its fundamental benefits compared with traditional methods have led to educational and training institutions, private hearing aid dispensaries, medical practices and hospitals throughout the world integrating it into their training and staff development programmes within a short time after the product launch.

Otis users report
"Otis Edition Pro is an important component of our skills laboratory. It enables our audiology students to practice core audiometry skills in a safe environment and to experience real-to-life case-based audiometry scenarios. Experiential learning in a virtual environment such as this means that students can make numerous attempts and succeed or fail without the real world consequences. Otis is a useful tool to teach students the process of test selection and data collection and allows them opportunities to tackle more complex cases than they may routinely encounter. They also receive feedback from the learning environment which helps them to build their skills and confidence ready for their final practical competency exams. We also recommend Otis (student version) to our students so that they can also continue to safely practice audiometry away from the skills laboratory."

"Otis – virtual patient” is a great piece of software both for audiologists in training and for specialists who don’t perform audiometry on a regular basis. It definitely has a few very strong features that I would like to point out. Firstly, it is case-based. Instead of just learning how to perform audiometry you are actually managing a specific case. It makes it very realistic. Additional information (clinical history, tympanometry and tuning fork tests) is available for each case that improves the interpretation of the test. Though, I think clinical picture could include more information. Both adult and paediatric cases are included in the test that helps understand the difference in results from children and adults." Read the whole Interview

"Otis can offer the student/trainee hands-on computer-based training in air conduction, bone conduction, and masking test exercises. Otis would be an excellent compliment to the student experience that includes appropriate testing of live clients. Exercises can be submitted online for evaluation by a mentor for evaluations of time and accuracy. Additional modules ask for short answer test reports. This training program is well designed and would be beneficial for most any beginning-level student in the hearing healthcare field."
