Patent ID: 6947031

Claim:
Data processing apparatus configured to generate data representing displayable characters in response to receiving signals from an input sensor, said signals corresponding to positions of mechanical interactions with said sensor, said apparatus comprising: processing means configured to process data derived from said signals from said input sensor including data of a first type corresponding to the position of a mechanical interaction with said input sensor and data of a second type corresponding to the absence of a mechanical interaction with said input sensor, wherein when mechanical interactions at different positions with said input sensor overlap in time said processing means is configured to generate data representing a first character in response to processing an item of data of said second type followed by data of said first type corresponding to the position of a first mechanical interaction with said input sensor, and to generate data representing a different second character in response to processing an item of data of said second type following data of said first type corresponding to the position of a second different mechanical interaction with said input sensor.
