| 发明名称 | Method and device for sensing rotation of wheel in portable terminal | ||
| 摘要 | A method of sensing the rotation of a wheel in a portable terminal is provided. The method includes producing at least one interrupt through any one of a plurality of sensors provided in the wheel according to the rotation of the wheel, confirming an interrupt value of the produced interrupt, and a status value of a sensor which did not produce the interrupt among the plurality of sensors, and determining that the wheel is rotated in a direction corresponding to the interrupt value and the status value. | ||

| 主权项 | 1. A method of sensing a rotation of a wheel in a portable terminal, the method comprising: storing at least one mapping table which correlates interrupt values and the status values of a plurality of sensors to the rotation of the wheel; producing at least one interrupt through any one of the plurality of sensors provided in the wheel according to the rotation of the wheel; confirming an interrupt value of the produced interrupt and a status value of a sensor which does not produce the interrupt among the plurality of sensors; and determining that the wheel is rotated in a direction corresponding to the interrupt value and the status value with reference to the at least one mapping table. | ||
