Xiaomi has patented a lie detection system based on a technology that analyzes the movement of the eyes through a mobile device with a telephoto lens that, based on the trajectory of the pupil, determines whether the subject is telling the truth or not.
The technology company Xiaomi Mobile Software Co has patented this technology under the description “polygraph method, device, mobile terminal and storage medium”, as collected by the Chinese media IT Home.
In this sense, in the patent document the technological company indicates that the this polygraph consists of a mobile device that includes a telephoto camera and a storage unit.
The telephoto lens has support to adjust the shooting angle of the camera with “pan and tilt”, which allows it to be record eye movements by precisely adjusting the camera to the face and subject’s eyes. With this, the system analyzes the movements and trajectory of the pupil.
Based on pre-established conditions and depending on the movements that the subject makes with his eyes, such as the dilation of the pupils or the number of times he blinks, the system is able to determine if these conditions are being met. If yes, the user is declared to be lying.
In addition, when indicating that it is a system compatible with portable devices, It is understood that this Xiaomi polygraph may be used on ‘smartphones’ or tablets if it is finally developed.
It should be noted that in recent weeks the Asian company has shown to be very interested in offering new devices that provide more immersive experiences using augmented reality technology.
What characteristics do the AR glasses that Xiaomi presented at the MWC have?
Augmented reality (AR) glasses Wireless AR Smart Glass Discovery Editionhave a screen that adapts to the retina level and gesture tracking technology, which accurately registers the movement of the hands and interacts based on the movements made by the user.
The Chinese company showed the prototype of this product at the technology fair Mobile World Congress (MWC), which was held in Barcelona. The company explained that those wireless glasses are meant for the individual user experienceThat is, without having to rely on a wired connection to a device. To do this, it uses “high-speed interconnection buses” of its own development.
As for its design, these smart glasses are built with lightweight materials, including a magnesium and lithium alloy, as well as carbon fiber parts. It also has a self-developed siloxygen anode battery.
Its weight is 126 grams, which allows to minimize “any physical load for the user” and translates into greater comfort during use.
On the other hand, the company revealed that the glasses have been precisely calibrated, taking into account details such as the center of gravity, the angle, the support of the nose and even the separation of the legs.
On the other hand, the Chinese company stated that with this device it intends to “achieve the perfect integration between the digital” and the real. In this sense, the brand considers it essential that users perceive virtual objects with the same intensity and clarity as physical ones.
For this reason, the brand has made it a device with a display quality “retina level”. This refers to the level of granularity that the human eye supports.
When the angular resolution or pixels per degree (PPD) approaches 60, the human eye stops distinguishing that granularity in the image. However, Xiaomi proposes a PPD of 58, making this product “the closest the industry comes to meeting this quality specification.”
Are glasses use an optical module comprising a pair of MicroOLED displaysIn addition, they also incorporate a light guide to achieve a sharp image. On the other hand, they incorporate some prisms that are capable of performing a “complex refraction” of light in a limited volume. With all this, the content displayed on the screen is reflected on three surfaces within the light guide prisms.
On the other hand, the Asian company has commented that the design of the optical module of the glasses is designed to minimize the loss of light and manages to generate clear images with a brightness of up to 1200 nits.
On the other hand, smart glasses come equipped with electrochromic lenses, that is, they can adapt to different lighting conditions. With the push of a button, these lenses allow the glass to go dark for a more immersive experience when viewing content.
However, if you keep the transparent mode on the lenses of these AR glasses, you can enjoy a “more vivid” augmented reality experience, in which real and virtual elements are combined.
