In order to provide the accuracy of test data for manufacturer, we use Walt Latency measurement equipment by Google.Įlectromagnetic radiation is more or less exist in the environment and this radiation may have a certain degree of impact on the most electronic and electrical equipment. Thus, Google has defined the specification of the highest delay time. Most of users always expect the device’s response time should be as fast as possible otherwise, if the device occurs delay, it may lead to a bad experience to users and decrease their desire to use Chrome OS. In touch screen and touchpad test section, we will check the equipment sent by the manufacturer that must not exceed Google’s specification of linearity offset. When linearity offset is too large, users can easily see the lines drawn by them are jittering on the touch device. Linearity Error is an important indicator to measure the quality of touch devices. In this test, the touchscreen and touchpad must respond correctly to below listed user gestures. There are many touch gestures built into Chrome OS that simplify tasks when using Chrome browser for users. There are three major tests in the Chromebook touchscreen and trackpad. The good touch performance/feedback will leave good experience of Chrome OS to users that will also lead them to be willing to explore the Chrome OS. The touchscreen and the touchpad are the most important parts of the Chromebook. Moreover, we provide fast and accurate test environment for brand company and component manufacturers that can assist customers to understand the content of the AVL test as well as provide the suggestion when the components need to be improved.īy far, Allion is able to offer the Approved Vendor List testing service for several components: Since 2016, Allion has worked closely with Google and become Google’s third-party Chromebook Approved Vendor List test lab to help Google improve the quality of the components. Moreover, in the Approved Vendor List certification, Google defines the requirement of minimum specifications and features for each component, and also defines the requirement for items’ verification testing. When the brand company plans a new Chromebook product, they must select the certified components from the list in order to bring a sufficient performance experience to end user. The certified components will be listed on the AVL (Approved Vendor List).
