Evaluation of an interactive multi-media device for delivering information on Le Fort I osteotomy . This study was carried out on volunteers to evaluate a newly developed interactive software package aimed at informing prospective Le Fort I osteotomy patients regarding the surgical technique and possible complications . The aim of the study was to compare two methods of information delivery ; a multi-media tablet device delivering both graphic and verbal information , and an audio device delivering essentially the same information in verbal form only . The null hypothesis was that there would be no difference between the efficiencies of the two methods . The subjects ' ability to recall the information delivered by both devices was assessed using a questionnaire . The tablet device participants scored an average of 15.48 points , while the audio device participants scored an average of 268 points . The difference was statistically significant ( p < 0.001 ) , suggesting that the multi-media tablet device was more effective method .
