Embodiment Construction

[0016] overview

[0017] Conventional techniques utilized to test touch screens and other touch-sensitive devices are often difficult to reproduce. Consequently, test results from these conventional techniques can be inaccurate and difficult to interpret, and thus often fail for their intended use.

[0018] The acoustic touch sensitivity testing technique is described here. In one or more implementations, techniques are described in which acoustic techniques are utilized to test touch-sensitive devices, such as touch screens. For example, an acoustic sensor may be used to detect "when" contact is made with a touch screen of a touch screen device. The input detected using the acoustic sensor can then be compared to the input generated by the touch screen device in order to test the functionality of the touch screen device, such as to determine latency. Further discussion of these and other testing techniques can be found with respect to the following paragraphs.

Abstract

Acoustic touch sensitivity testing techniques are described. In one or more implementations, a touch-sensitive surface of a touch-sensitive device is tested by using an acoustic sensor to detect contact made with the touch-sensitive surface and comparing the data received from the acoustic sensor describing the contact with the data received from the touch-sensitive Data received by the device describing the contact.

Description

Background technique [0001] The display and input technologies utilized by computing devices are constantly evolving. For example, the first computing devices were equipped with monitors. A user interacts with a computing device by viewing simple text on a monochrome monitor and entering text via a keyboard that can then be viewed on the monitor. Other technologies, such as graphical user interfaces and cursor control devices, were then developed subsequently. [0002] Display and input technologies continue to evolve, such as by using a computing device's touch screen display to sense touch to recognize gestures. A user may interact with a graphical user interface, for example, by using the user's hands to enter gestures detected by a touch screen display or other touch-sensitive device. However, conventional techniques utilized to test touch screen displays and other touch sensitive devices are often inaccurate, so they are typically not suitable for testing touch screen ...
