The World Intellectual Property Organization (WIPO) website has published a new Huawei patent that appears to describe a new method of determining whether a wearable is being worn or worn. Oddly enough, there are no drawings or pictures associated with the patent internationally filed under publication number WO / 2018/053677. However, there are descriptions of how the method works and a general idea of what it should do. The patented idea primarily refers to a sensor array consisting of two sensors that detect whether a wearable is currently being worn or not. The patent was originally filed in 2016 before it was released today.
If we look more closely at the content of the WIPO patent, it turns out that the Huawei method uses two separate capacitive touch sensors. For clarity, these seem to be the same kind of technology that is usually embedded under the glass in a smartphone or tablet display. However, these should work in tandem instead of separately. In addition, they will not necessarily capture a single point of contact. Instead, the patent describes a process in which a "reading" can be taken from the first sensor and then compared to it by the second sensor. By determining whether one value is higher than the other or not, the wearable may decide whether the wearable is being worn or not. Moreover, the patent effectively only states that the use of the method will reduce the power consumption of the wearables in question.
In addition to the mystery of the patent and taking into account the fact that granting a patent does not mean that it will be used, there is no indication as to what type of device this would be used for. As it is used to detect a wear condition or otherwise, it could easily be used in any of the current portable technologies in the market. So that could be something as commonplace or everyday as a VR or AR headset, or something like a smartwatch or fitness band. The possibilities are seemingly endless. Suffice to say, this is likely to remain unclear until Huawei decides to make some form of official announcement about it – if it happens at all.
