Patent reveals definitive solution to the Drift problem

The Drift problem is considered one of the largest that exist in gamepads, particularly in these of SONY and Nintendo, as for Microsoft the possibilities of having this problem are a lot decrease than they happen. In any case, it isn’t a novel problem of a generalized model that additionally impacts generic drivers for PCs. Luckily a patent appears to have the definitive solution to the problem.

The patent that can finish the drift

Patent solution drift operation

The PixArt firm has a patent assigned to its title leading to the final solution to drift. This patent describes a mechanism, which is predicated in utilizing a picture sensor to learn the actions of an analog stick, mentioned picture sensor captures the deformations produced by the analog stick on a deformable floor discovered on it.

The deformable floor is situated on the inside physique of the analog stick, proper in the gap the place it shares house with the picture sensor, which from the deformations produced in the deformable half can interpret that the consumer has made one motion or one other with the analog stick.

This easy methodology eliminates the want for a potentiometer to measure analog stick actions. It is exactly a malfunction and a nasty calibration of the potentiometer that leads to 90% of the issues associated to the Drift. In addition, this solution may be very low-cost to implement and subsequently viable for all gamepads, no matter the platform.

Will we see this expertise in any product?


The Japanese newspaper Economic Daily News said in a information story final August 2020 that Nintendo will implement PixArt expertise in future revisions of its Joy-Con. There has been discuss for months of a Switch evaluate, which might use the similar SoC as the present evaluate, however that might include a Samsung OLED display screen as a substitute of the present IPS.

This revision has not but been introduced, however it might be a possibility for Nintendo to launch new Joy-Cons that might not have the Drift problem that has affected the controllers of the totally different fashions of the Nintendo Switch. Another firm that is perhaps focused on utilizing this expertise is SONY given the Drift issues in the DualSense of its PS5.

In any case, as it’s a patent exterior any of the three console manufacturers and any peripheral producer, which means it may be licensed for the creation of recent gamepads. In addition, the use of a picture sensor to learn the actions of the analog stick implies that the basic put on of the potentiometers won’t exist.
