Hi @infowash, sorry to hear about your experiences. I am afraid to confirm that indeed no more licence are being issues for analytical use in conjunction with the Tobii 4C (or ET5). Tobii Pro is the business unit that specialises in scientific and analytical use, whilst Tobii Tech have now focused toward gaming exclusively. Apologies for the inconvenience, however Tobii Pro is now the only option we can recommend for analytical use with Eye Tracking.
