Abstract
A tactile positioning device includes a film attached to a touch surface of a portable electronic device. The film includes at least a first tactile unit used as a positioning reference point of a key on the touch surface, and at least a second tactile unit being a linear tactile unit for defining an operating route or an operating range. The tactile feedbacks provided by the first tactile unit and the second tactile unit enable a user to sense a position of the key which is positioned by the first tactile unit and the operating route or the operating range defined by the second tactile unit, so as to operate the portable electronic device without having to look at the touch surface.

A tactile positioning device for eyes-free operation of a touch surface of a portable electronic device, comprising:
- a film attached to the touch surface of the portable electronic device, the film comprising:
- at least a first tactile unit used as a positioning reference point of a key on the touch surface;
- and
- at least a second tactile unit being a linear tactile unit for defining an operating route or an operating range;
- wherein tactile feedbacks provided by the first tactile unit and the second tactile unit enable a user to sense a position of the key which is positioned by the first tactile unit and the operating route or the operating range defined by the second tactile unit, so as to operate the portable electronic device without having to look at the touch surface.
An operating device for eyes-free operation comprising:
- a portable electronic device having a touch surface;
- and
- a tactile positioning device comprising at least a film attached to a partial range of the touch surface of the portable electronic device, the film comprising at least a first tactile unit used as a positioning reference point of a key on the touch surface, wherein an edge of the film defines an operating route or an operating range, and a tactile feedback provided by the first tactile unit enables a user to sense a position of the key which is positioned by the first tactile unit and a tactile feedback provided by the edge of the film enables the user to sense the operating route or the operating range defined by the edge of the film, so as to operate the portable electronic device without having to look at the touch surface.
An operating device for eyes-free operation having a touch surface for receiving a touch input, characterized in that:
- a linear tactile unit corresponding to an operating route of the operating device is disposed on the touch surface.
An operating method for eyes-free operation comprising steps of:
- providing a tactile unit on a touch surface of an operating device, and the tactile unit being used as a positioning reference point of a key;
- programming the operating device to not to respond to a finger search for the tactile unit on the touch surface;
- and
- programming the operating device to respond to a touch operation on the key or surrounding keys after the tactile unit is positioned by the finger search.
A method for controlling a backlight of a touch screen for an electronic device for eyes-free operation, comprising steps of:
- activating an eyes-free mode of the electronic device;
- detecting an inclined angle of the touch screen;
- and
- adjusting a brightness of the touch screen according to a predetermined relationship between the brightness and the inclined angle of the touch screen.
A method for controlling a backlight of a touch screen for an electronic device for eyes-free operation, comprising steps of:
- activating an eyes-free mode of the electronic device;
- detecting and identifying a face feature in front of the touch screen;
- and
- adjusting a brightness of the touch screen according to a predetermined relationship between the brightness of the touch screen in the eyes-free mode and the face feature.
