Who invented iphone touch screen

In , a "touch sensor" was developed by Doctor Sam Hurst founder of Elographics while he was an instructor at the University of Kentucky. The "Elograph" was not transparent like modern touch screens, however, it was a significant milestone in touch screen technology. In , the first true touch screen incorporating a transparent surface came on the scene developed by Sam Hurst and Elographics. In , Elographics developed and patented a resistive touch screen technology, the most popular touch screen technology in use today.

In , Siemens Corporation financed an effort by Elographics to produce the first curved glass touch sensor interface, which became the first device to have the name "touch screen" attached to it. Elographics Patents. In , the computer manufacturing company, Hewlett-Packard introduced the HP, a home computer with touch screen technology. The HP had a built-in a grid of infrared beams across the front of the monitor which detected finger movements.

However, the infrared sensors would collect dust and require frequent cleanings. The nineties introduced smartphones and handhelds with touch screen technology. In , Apple released the Newton PDA, equipped with handwriting recognition; and IBM released the first smartphone called Simon, which featured a calendar, notepad, and fax function, and a touch screen interface that allowed users to dial phone numbers. In , Microsoft introduced the Windows XP Tablet edition and started its entry into touch technology.

The value of finding key patents such as this is twofold - it can help acknowledge the inventor - and can be used to find other relevant patents in the field. And for this, we will use the Ambercite Ai patent analytics software.

In this case, we will use US to understand these sorts of questions:. Running such as a search is remarkably easy. We set up the query within Ambercite Ai as follows:. And this will produce a list of prior art patents, ranked according to similarity to the starting patent, with the five most similar patents shown below click on the image for an interactive version. This query produced patents in total. Top of the list for similarity was US, filed by General Electric for a Touch-sensitive optoelectronic circuits and indicators.

While similar in concept, this was more about buttons than screens. Similarly, while we have not reviewed all 75 prior art documents in detail. Check out what US looks like in the middle of an interactive patent network at the Amberscope link found here. Again, this can be a simple query, based on looking for similar patents filed after US Again we might look for the most similar patents:. But how can we assess these patents?

Ambercite has developed a metric called Amberscore, which predicts the importance of patents based on the number, strength and age of its citation connections. But not in this set - instead we find three patents with Amberscore values in excess of ! As an analogy, this would be like reviewing a list of bank accounts, and coming across the bank balance of Bill Gates again click on this for an interactive version.

Third on the list, with an Amberscore of , is US , filed by the University of Delaware in for a Method and apparatus for integrating manual input.

When longtime marketing executive Phil Schiller told Jobs that the customers were picketing and were very angry, Jobs replied:. They have every right to be angry. They love Newton.
