Abstract
Specific ambient and user behaviour sensing systems and methods are presented to improve friendliness and usability of electronic handheld devices, in particular cellular phones, PDAs, multimedia players and similar.
The improvements and special functions include following components:
- a. The keypad is locked/unlocked (disabled/enabled) and/or the display activated based on the device inclination relative to its longitudinal and/or lateral axes.
- b. The keypad is locked if objects are detected above the display (for example the boundary of a bag or pursue).
- c. The keypad is locked/unlocked (disabled/enabled) and/or the display activated based on electric field displacement or bio-field sensing systems recognizing the user hand in any position behind the handheld device.
- d. The electric response signal generated by an electric field through the user hand in contact with a receiver plate is used to identify the user and in negative case lock the device.
- e. Connection with incoming calls is automatically opened as soon as a hand is detected behind the device and the device is put close to the ear (proximity sensor).
- f. The profile (ring-tone mode, volume and silent mode) can be changed just putting the device in a specific verse (upside up or upside down).
- g. Has a lateral curved touchpad with tactile markings over more surfaces to control a mouse pointer/cursor or selection with the thumb finger.

- 2. The method of claim 2, wherein the input keys are mechanic or electronic, push-down, rotational, switch-based, touch-pad, touch-screen or an equivalent.
- 8. An electronic handheld device with input keys being locked/disabled if an object is sensed in front of the device display within a certain distance.
- 17. An electronic handheld device with input keys being unlocked/enabled and/or a display being activated when the hand interference in an electric field created behind or around the handheld device is detected.
- 24. A mobile phone having a locked status and using the electrical response signal generated by an electric field through the user hand in contact with a receiver plate as user identification method to unlock it.
- 29. A mobile phone that opens the connection to incoming calls automatically without any key press when a hand is sensed behind the device and an object close to the loudspeaker is detected.
- 35. A mobile phone whose profile changes or can be configured to change depending on the verse how it is positioned on a quiet surface (upside up or upside down).
