Problems solved by technology

This would result in the keypad being left unlocked which in turn could potentially cause accidental phone calls etc.
While chrono locks partially solve this problem, there are still timeout periods when random key presses can initiate unintentional phone calls or interfere with the operation of the device, such as entering entries in the calendar or entering names in the phone book

Abstract

An input device including a support structure, such as a Printed Circuit Board (PCB), and a switch device, e.g. a switch dome, mounted on the support structure. The switch device may be configured toprovide tactile feedback to a user upon depression of the switch device by a finger of the user. The input device also comprises a capacitive touch sensing device, e.g. a capacitive touch screen, which is positioned in relation to the switch device such that the capacitive touch sensing device is configured to sense the capacitance of the finger upon depression of the switch device by the finger.The invention also concerns an electronic device, e.g. a mobile phone, comprising one or several input devices.

Description

technical field [0001] The present invention generally relates to an input device for inputting information to an electronic device. The invention also relates to an electronic device, such as an electronic device comprising one or more of said input means, eg a mobile terminal such as a mobile phone, a personal digital assistant (PDA), a digital camera, and / or a handheld computer. Background technique [0002] Various portable electronic devices, such as mobile terminals (eg, mobile phones, PDAs, media players and / or handheld computers) are widely used. In many of these electronic devices, the keyboard can be locked when the portable electronic device is not in use. There are a number of different ways to implement the keyboard lock feature. Some mobile terminals use two different key press sequences to lock the keyboard. Some other terminals utilize features like timer lock or keypad lock selection from menus. [0003] It is known in the prior art that the keypad of a ...
