15. A methodology for development augmented reality applications using mobile phones and sensors devices. / Uma metodologia para o desenvolvimento de aplicações de realidade aumentada em telefones celulares utilizando dispositivos sensores.
Handheld Augmented Reality or Handheld AR is the implementation of Augmented Reality (AR) systems into handheld devices. Handheld AR applications use the handheld devices camera to recognize markers (inserted into the environment). This process enables data entry into AR system. The response generated for these applications are presented as virtual images (3
