Thank you Dennis! We are excited about the RTI Mobile app as well and are hopeful that through the use of mobile devices we will be able to engage more users with this terrific technology.
Thank you also for your feedback and questions regarding the pricing of the RTI Mobile app. The app has been in development for two years now by independent developers (Artis CT), we have largely been a team of two, including myself (a paper conservator) and Cornell (a programmer). I assure you that we have been extremely dedicated in developing the RTI Mobile app and generous with our time as well to create a product that will hopefully bring RTI technology to a wider audience.
Regarding the RTI Mobile app being made possible by the use of free software developed by CHI and other researchers, without a doubt we truly value their work and mean no disrespect in charging for the app; however, there are many paid apps currently available that have been built under the same premise, such as tutorial, medical and photo/video apps.
Initially the RTI Mobile app was designed for use in exhibition spaces as a part of gallery or museum installations to further engage visitors with objects, the price of the app therefore reflects the absorption of the cost by an institution rather than an individual in a niche market. There are also the ongoing costs of development including having a UI artist, programming updates, advertising, research and development etc. In hindsight it is clear that this has made the app less accessible to the very people who already enjoy using the technology, we apologize, that was not the intention. With that said we are looking to the RTI community to help us get it right, please take the time (2-3 minutes) to fill out our feedback survey (https://www.surveymonkey.com/s/SQSYTLC) and let us know your opinion about the features, design and pricing of the RTI Mobile app. We appreciate your kind words and thank you for your interest in the RTI Mobile app.
