Talking pen with voice navigation

Abstract

The invention relates to a talking pen matched with a map, which comprises a talking pen adopting optical identification data and digital processing technology and a matched map printed with invisible codes. When the talking pen touches the map, a sensing head at the pen head of the talking pen touches invisible codes corresponding to any character or drawing on the map, the shot bar code information is transferred to a circuit board processor by filtering and shooting of a filtering camera, then a GPS (Global Positioning System) module on the circuit board processor can automatically navigate according to the current position, the circuit board processor converts the acquired information into voice signals through comprehensive analysis, and voice navigation data on a flash memory chip is called to send the stored bar code content through a loudspeaker in the form of sound. The invention effectively overcomes the defects that ordinary people have defects of reading drawings, the map can not be used easily, the marked geographic information is limited, and the like, is convenient for traveling of people, obviously improves the functions of the commercially available talking pens, and enlarges the application range and the application population.

Description

technical field [0001] The invention relates to the field of GPS navigation, in particular to a point reading pen using digital voice and invisible identification code technology, which can be used in conjunction with maps for voice navigation. technical background [0002] The reading pen is a high-tech product using the latest international optical image recognition technology. It adopts high-resolution optical discrimination invisible code technology, digital speech synthesis and restoration technology, digital signal information processing technology, digital flash memory technology and image processing technology. It is a high-tech product combining playback technology and paper printing technology. High-resolution optical recognition replaces electromagnetic recognition, and two-dimensional code digital recognition replaces analog recognition, which fundamentally eliminates the hidden dangers of electromagnetic radiation caused by previous point reading pens.

Problems solved by technology

[0004] The problem to be solved by the present invention is to provide a point-reading pen that can be used with a map in view of the shortcomings of the existing point-reading pen that has a single function and cannot navigate. Text or pictures, you can hear the relevant voice navigation prompt information from the reading pen, making the reading pen more widely used and groups

When browsing the map, point the reading pen to the text or image printed with the invisible code, the speaker of the reading pen will send out the corresponding voice navigation information, providing an electronic voice navigation map, which realizes the convenient and fast search for the map At the same time, you can also set the navigation arbitrarily, which solves the defects that the existing map cannot make sound or navigate, and improves the efficiency of map use.
