As tablets and smart devices become increasingly popular, touch interfaces have changed how we interact with devices. Even traditional laptops have implemented touchscreen designs. This led to the birth of the Universal Stylus Initiative (USI). Various tech companies developed the USI, including Google, Wacom, Intel, Dell, HP, Lenovo, and others. The goal of USI is to establish a universal touchscreen stylus standard, ensuring that laptops, tablets, and other smart devices that support USI standards can be used interchangeably. Users will be able to use a USI stylus on different smart devices made by different manufacturers, leading to a consistent note-taking or drawing experience.

Common Issues of USI Styluses

However, is this goal possible to achieve? As a consultant for many major manufacturers, Allion has verified thousands of products and has understood the real usage problems for users. In the figure below, it can be seen that compatibility is the main reason why users return their products.

According to our in-depth analysis, incompatibility and functional abnormalities are the main problems users are most concerned with. Below are some user scenarios that often occur among users:

  1. Many consumers often purchase USI styluses when their laptops lack support for them. This is because major laptop manufacturers do not mention much about USI compatibility.
  2. Although the device’s system claims it supports USI, the stylus cannot establish a connection.
  3. The USI stylus is extremely sensitive. This is because the styluses do not support the hover function like the Apple Pencil. When the stylus is near the screen, random lines will be drawn on the smart device, making it impossible for users to write or draw.
  4. The built-in eraser function of the stylus is malfunctioning.
