Here's how you can enhance efficiency as an experienced AR developer with problem-solving techniques.

Conduct rigorous tracking of code changes through detailed logs, allowing you to identify when and where specific issues began to occur. This can significantly speed up error identification. Use team code review practices to ensure different perspectives are considered, helping to spot bugs that may not be visible to the original developer. Implement performance metrics to monitor how code updates affect the app's efficiency, making it easier to detect bugs that negatively impact user experience.

Divide y vencerás. Dividir el problema y aislar sus posibles causas permite encontrar aquello que falla o aquello a mejorar. Por ejemplo tener una escena simple donde probar el plane / world tracking, otra donde probar botones de redimensionamiento de elementos 3D, etc Sin embargo también es importante conocer las características de la tecnología que se maneje como por ejemplo Vuforia te ofrece una imagen estilo QR que es detectada como plano/suelo y te permite testear plane tracking de forma mucho más cómoda. Unity también ofrece algunos packages para testear en el dispositivo mediante conexión Wifi sin estar atado a cables. Meta Spark y Effect House te ofrecen soluciones dentro de la misma plataforma para testear cámaras simuladas.

Add debug messages in specific functions to the code, to easily identify errors. Testing the program on a real device is the best way to detect possible errors that appear in a cleaner way.

When implementing simple UIs like buttons or labels, hiding them doesn’t usually cause any issues, as they remain in memory without significant impact. However, in AR apps, even small, unnecessary objects or those not required in certain scenarios should be carefully managed. Otherwise, they can negatively affect the user experience.

Identify which will be the final device of your program. In general, for mobile devices you have to reduce the resolution of the images and transform the audio into mono output.

Contextual user testing is a backbone of a successful AR experience. This followed up with contextual feedback helps you iterate accordingly and add to the Eventual experience design .

Having testing sessions is very important. In augmented reality applications, testing on the final device is the best way to detect errors and have a real user experience.

I would like to complement the text with the idea that collaboration not only enhances creativity but also strengthens idea validation. By involving experts from different fields, such as psychology and education, it's possible to tailor AR experiences to various needs. This ensures that solutions are inclusive and impactful, enhancing the end-user experience.

You have to keep in mind that you are never developing just a thing, you are always developing an experience, and and experience is always different for each one, so you need to create the experience in a way that most of your target people can connect with it sharing and prototyping with them, let your creation be shaped by their interaction, and do not ask directly "did u like it?" that will be always a yes but is a lie, be creative in the ways that you can get the information without asking directly to them, like creating challenges, or measuring the time that it takes for them to get into some information

Structure and write your code in such a way that you don't have to think about it when making changes, The great thing about applications which let you create AR experiences is they work on ECS, think of any feature like a component, If you follow this approach you will be more efficient, and will be able to provide better and more complex experiences to users.

Apunten siempre al usuario, todos los desarrollos tanto con RA como nuevas tecnologías es fundamental el usuario donde va a ejecutar tu solución, no es algo menor.
