Abstract: A portable computer having a touch pad as the pointing device adopts a touch pad input control function in accordance with the principles of the present invention. The portable computer system is provided with an input device interface for receiving pointing data generated in the touch pad and for detecting a quantity of time elapsing between occurrence of the pointing data. When the quantity of time exceeds a preset value, the input device interface disables input of the pointing data from the touch pad. The input operation of the pointing data is resumed when pointing data corresponding to a predetermined pattern is inputted. Preferably, the predetermined pattern corresponds to a closed curve which disregards the area and curvature of the closed curve. According to the principles of the present invention, unnecessary pointing operations which occur during inadvertent touches of the touch pad can be effectively prevented.
