BACKGROUND OF THE INVENTION

The present invention relates generally to a portable hand-held reading device that captures print information through digital scanning, and reproduces the information via text-to-voice technology and on a flat-panel display. All these processes are performed within the device without the intervention of additional external devices.

The freedom to read anywhere, anytime, and regular information to include newspapers, is of vital importance that can be exploited by blind and visual impaired persons in many circumstances.

Currently, blind and visual impaired persons are confined to the use of desktop PC to access information. The ease of access to information is dependent on certain standards that programmers adhere to that enable assistive technology, such as screen readers, to read and/or convert electronic information. The use of flatbed scanners, CCTV, and Kurzweil are required to read print materials. These devices are usually in a special or specific location of a work environment or academic institution.

The digital scanner plays a vital role in the conversion between paper and electronic information. However, while scanners are ideal for users to communicate print information with colleagues through various electronic mediums, they lack portability and hence, blind and visual impaired users are confined to the location of the scanners. In effect, they lack the convenience and flexibility to blind and visual impaired persons to access information anytime, anywhere. Hand-held scanners are an improvement, U.S. Pat. No. 6,396,518 to Dow et al., but are dependent on external units, such as a computer, printer, or facsimile machine to communicate scanned images. U.S. Pat. No. 6,218,963 to Ellis discloses a digital reading pen that is designed to be dependent on a monitor or printer so that scanned information can be magnified for reading or printing.

Moreover, what is sought is a portable, hand-held reading device that allows users to read in real time captured print information without the intervention of external devices.

In addition, the portable hand-held reading device provides cordless operation with the exception of a headphone unit that may be connected into device to listen to the scanned information.

SUMMARY OF THE INVENTION

An object of the present invention, a portable hand-held reading device, is to provide the user, in particular, a blind or visually impaired person the ability to read print information anywhere, anytime.

Another advantage of the present invention includes both text-to-voice technology and flat-panel display, giving the user the option to listen to text read only, listen to text read and simultaneously read text on flat-panel display, or to read text only on the flat-panel display.

Another advantage of the present invention is that all functions are done internally without the invention of external devices to convert text to voice and/or to display information on the flat-panel unit.

Still another advantage of this invention is a microphone for receiving dictated information giving the user the option to listen to a familiar voice such as that of the user, or of a member of the user's family or friends, rather than listen to the voice programmed in the device.

A further advantage of the invention is that the device automatically pauses when the device is not in contact with paper, and appends information when contact resumes while the image capture buttons are depressed.

Yet another advantage of the invention is the ability of the device to automatically delete information when scanning resumes for new information after the conversion to text-to-voice technology and/or text display on the flat-panel display, thus efficiently utilizing storage.

Still another advantage of the invention is the ability to save selected information before resuming to capture new information.

A further advantage of the invention is the display of text one sentence at a time, in Marquee style, giving the user the ability to magnify the font to desirable size, without having to display an entire page on the panel.

Another advantage of the invention is the navigation buttons. The left button allows the user to read the previous sentence, the right button the next sentence, the up button the previous paragraph, and the down button the next paragraph. The up and down buttons give the user the option to scan information rather than read sentence by sentence.

Still another advantage of the invention is the ease of use by both left and right-handed users afforded by image capture buttons on either side of the device.

DETAILED DESCRIPTION OF THE INVENTION

As shown inFIG. 1A, a portable hand-held reading device depicts one side (i.e. front) of appliance1where a flat-panel display2along with user operation buttons3,4,5,6,7, user navigation buttons8,9,10,11, and microphone13are located. Display2is preferably of the flat-panel assortment to accommodate larger fonts and marquee style display of scanned information of device1. Display2is one of the means by which scanned print information is communicated to the user. As used herein, the term information means print text. The power switch3turns the device on and off. The user operation buttons comprise Braille and text imposed Read button4, Braille and text imposed Display button5, and Braille and text imposed Word button6. The buttons will be large enough to accommodate the shortest and communicable Braille word (for example, word is substituted for dictionary because it is shorter). Help button7provides the user with access to how-to instructions on the operation of device1. The navigation buttons include an up button8, a down button9, a left button10, and a right button11and are controlled by the user. To view previous read and/or displayed information a sentence at a time, the users presses button10; to view the next or following sentences, the users presses button11; to view previous information a paragraph at a time the user presses button8, and to view or skim information paragraphs at a time the user presses button9. Microphone13for receiving audible information either from the user or the family of the user so that information read back to the user is in a familiar voice.

FIG. 1Bshows the side of device1opposite that illustrated inFIG. 1A(i.e. back). The opposite side of device1includes photoelement array15through which information is captured into memory.

A capture button12included at one side of device1as depicted inFIG. 1C, and a capture button12located at the other side of device1as depicted inFIG. 1Dare both accommodating to right-handed and left-handed users to satisfy the ergonomic requirements of users. A headphone outlet14as depicted inFIG. 1Eis located at the bottom end of device1minimizing the interference of the headphone line/cord with the physical process of the user scanning information.

FIG. 2shows two inputs to device1, with the inputs being the photoelement array15for capturing information and the microphone13for receiving audible information from the human voice. However, it should be noted that device1is not limited to photoelement array15input; other inputs in the market that will perform the same function more efficiently and economically can be substituted.

FIG. 2further shows two outputs for the reading device1, with these two outputs being the speaker14and display2.

FIG. 2shows that the processor and memory, to include application software such as text-to-voice technology, are in communication with each other and other components of device1.

When the user turns device1on through power switch3, the user has the option to press Read button4, scan information and have the information read back to the user utilizing text-to voice technology either in user's own voice, the voice of user family, or the default voice through a headphone connected to headphone outlet14. While scanning both capture buttons12are depressed, applying more pressure to one than the other will not affect scanning. Both buttons are provided to accommodate different user strengths and preferences. If device1loses contact with the paper temporarily while capture buttons12are depressed, scanning pauses and will append when contact is made again on paper (this is to make the scanning of large paper such as newspapers easier). If the user wants to display text only on the display panel, the user presses Display button5after the power switch3is turned on. Text is displayed white on black, the preferred mode of visual impaired persons, one line at a time (Marquee style) thus allowing the user to increase font size from default size of 16 points to either font size of 18 or 20 points. If the user wants to both listen to and display text, after turning device1on through power switch3, the user presses Read button4and Display button5within seconds of each other to have the information read back to the user through the use of a headphone that is connected to headphone outlet14. While in the process of reading, to verify the meaning of a word, the user presses Word button to activate the dictionary, and the meaning of the last word read is given.

Information read through the headphone connected to headphone outlet14, and/or displayed on display2is automatically deleted when scanning resumes, thus freeing storage space unless the user specifies information to save. To save previous paragraph read the user presses navigation button8twice.
