“…Different types of computer stylus pens (or styli) exist that support pen computing interfaces [27]. The first types are the passive styli, which include a capacitive-type touch system (CTS) styli [28][29][30], and digital pens that further include Electromagnetic Resonance (EMR) styli (e.g., Samsung Galaxy Note 10 S-Pen (Samsung S-Pen: https://www.samsung.…”

“…For example, the Apple pencil is using a multiaxial force sensor, which enables three dimensional force estimation and is important for high fidelity stroke digitisation [34]. Such a feature is not available in C-type passive styli that use a larger and rounded tip for robust detection [27].…”

“…As the relative positions of the tip and ring electrodes (measured from the surface of the touchscreen) increased, such a set-up resulted in the improper sensing of the stylus position and tilt, as well as in the generation of random ghost stroke events. This was a result of the improper interpretation of acquired signals by the controlling software due to distorted capacitance variations between electrodes after stylus modification [27]. It is possible to reconfigure the software setting to compensate for altered capacitance fingerprinting; however, such a solution is highly problematic, as it requires low level driver access, which is commonly not available in off-the-shelf stylus systems.…”

The distinct properties and affordances of paper provide benefits that enabled paper to maintain an important role in the digital age. This is so much so, that some pen–paper interaction has been imitated in the digital world with touchscreens and stylus pens. Because digital medium also provides several advantages not available to physical paper, there is a clear benefit to merge the two mediums. Despite the plethora of concepts, prototypes and systems to digitise handwritten information on paper, these systems require specially prepared paper, complex setups and software, which can be used solely in combination with paper, and, most importantly, do not support the concurrent precise interaction with both mediums (paper and touchscreen) using one pen only. In this paper, we present the design, fabrication and evaluation of the Hybrid Stylus. The Hybrid Stylus is assembled with the infinity pencil tip (nib) made of graphite and a specially designed shielded tip holder that is attached to an active stylus. The stylus can be used for writing on a physical paper, while it still maintains all the features needed for tablet interaction. Moreover, the stylus also allows simultaneous digitisation of handwritten information on the paper when the paper is placed on the tablet screen. In order to evaluate the concept, we also add a user-friendly manual alignment of paper position on the underlying tablet computer The evaluation demonstrates that the system achieves almost perfect digitisation of strokes (98.6% of strokes were correctly registered with only 1.2% of ghost strokes) whilst maintaining excellent user experience of writing with a pencil on the paper.

“…EMR (Electro Magnetic Resonance) passive stylus and capacitive active stylus can offer higher accuracy performance and better writing experience than finger and capacitive passive pen. [1] EMR passive stylus needs an extra EMR sensor under the display. That is why EMR stylus has higher cost and thicker thickness than capacitive active stylus.…”

In this work, we propose active stylus application using selfcapacitive touch with OLED TDDI. Active stylus application using self‐capacitive touch sensor has several benefits in comparison to using mutual‐capacitive touch sensor, such as “Smaller RC Loading in Active Stylus Sensing”, “Uplink Signal Partially Driving”, and “Downlink Signal Through Palm Removing”. With these benefits, active stylus application can get better writing experience and accuracy using self‐capacitive on OLED On‐Cell product. Finally, we propose the word wide first OLED TDDI (Touch and Display Driver Integration) NT38770 passed Wacom LV1 certification with 6.67” OLED module.
