Os dispositivos de entrada baseados em toque direto substituíram os tradicionais e se tornaram a principal tecnologia interativa para dispositivos portáteis. Embora a interação por toque direto se mostre fácil de usar, seus problemas, por exemplo, o problema de oclusão e o problema do dedo gordo, diminuem a experiência do usuário. A interação móvel baseada em câmeras é uma das soluções para superar os problemas. Existem dois estilos de interação típicos para gerar interação de apontar baseada em câmera para dispositivos portáteis: mover o dispositivo ou mover um objeto antes da câmera. No primeiro estilo de interação, existem duas abordagens para mover a posição de um cursor na tela do dispositivo portátil: movê-lo na mesma direção ou na direção oposta para a qual o dispositivo se move. Neste artigo, são apresentados os resultados de uma pesquisa comparativa, que comparou o desempenho de apontamento de três técnicas de apontamento baseadas em câmera. Todas as técnicas de apontamento utilizaram informações da câmera traseira. Os resultados indicam que o estilo de interação de mover um dedo diante da câmera supera o outro em eficiência, precisão e rendimento. Os resultados também indicam que dentro do estilo de interação de mover o dispositivo, o estilo de posicionamento do cursor de mover o cursor para a direção oposta é ligeiramente melhor que o outro em eficiência e rendimento. Com base nas descobertas, sugerimos dar prioridade ao estilo de interação de mover um dedo ao implantar técnicas de apontar baseadas em câmeras em dispositivos portáteis. Dado que o estilo de interação de mover o dispositivo suporta a manipulação com uma mão, também vale a pena implantá-lo quando for necessária a interação com uma mão. De acordo com os resultados, o estilo de posicionamento do cursor de mover o cursor na direção oposta à qual o dispositivo se move pode ser uma escolha melhor.

Abstract: Input devices based on direct touch have replaced traditional ones and become the mainstream interactive technology for handheld devices. Although direct touch interaction proves to be easy to use, its problems, e.g. the occlusion problem and the fat finger problem, lower user experience. Camera-based mobile interaction is one of the solutions to overcome the problems. There are two typical interaction styles to generate camera-based pointing interaction for handheld devices: move the device or move an object before the camera. In the first interaction style, there are two approaches to move a cursor's position across the handheld display: move it towards the same direction or the opposite direction which the device moves to. In this paper, the results of a comparison research, which compared the pointing performances of three camera-based pointing techniques, are presented. All pointing techniques utilized input from the rear-facing camera. The results indicate that the interaction style of moving a finger before the camera outperforms the other one in efficiency, accuracy, and throughput. The results also indicate that within the interaction style of moving the device, the cursor positioning style of moving the cursor to the opposite direction is slightly better than the other one in efficiency and throughput. Based on the findings, we suggest giving priority to the interaction style of moving a finger when deploying camera-based pointing techniques on handheld devices. Given that the interaction style of moving the device supports one-handed manipulation, it also worth deploying when one-handed interaction is needed. According to the results, the cursor positioning style of moving the cursor towards the opposite direction which the device moves to may be a better choice.
