1. A method, comprising:
- testing a touch-sensitive surface of a touchscreen device by;
receiving at the touch-sensitive surface a contact;
detecting the contact by both a first sensor part of the touch-sensitive surface and a second sensor of a test apparatus, the second sensor being an acoustic sensor, the first sensor being a type other than acoustic, the touch-sensitive surface not containing an acoustic sensor usable to detect the contact, and the second sensor being separate and distinct from the touchscreen device and not used by the touchscreen device to detect the contact;
sending first data from the touchscreen device to the test apparatus, the first data describing the contact as detected by the first sensor; and
determining an ability of the touchscreen surface to accurately detect the contact by comparing the first data to second data, the second data describing the contact as detected by the second sensor.

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

9. A test apparatus comprising:
-
an acoustic sensor configured for placement proximal to a touch-sensitive surface of a touchscreen device, the acoustic sensor separate and distinct from the touchscreen device and not used by the touchscreen device to detect a contact made to the touch-sensitive surface; and at least one module that detects the contact by both the acoustic sensor and a first sensor part of the touch-sensitive surface, the at least one module configured to; receive first data from the touchscreen device describing the contact as detected by the first sensor, the first sensor being a type other than acoustic; and determine an ability of the touch-sensitive surface to accurately detect the contact by comparing the first data to second data, the second data describing the contact as detected by the acoustic sensor. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system comprising:
-
a first sensor part of a touch-sensitive surface of a touchscreen device, the first sensor being other than an acoustic sensor, the touch-sensitive surface not containing an acoustic sensor usable to detect a contact with the touch-sensitive surface; a second sensor, the second sensor being an acoustic sensor, the second sensor being separate and distinct from the touch-sensitive surface and not used to detect the contact; at least one processor and a memory; the memory including at least one module including executable instructions that when executed on the at least one processor is configured to detect the contact by both the first sensor and the second sensor by; receive first data associated with the touch-sensitive surface describing the contact as detected by the first sensor; and determine an ability of the touch-sensitive surface to accurately detect the contact by comparing the first data to second data, the second data associated with the second sensor describing the contact detected by the second sensor. - View Dependent Claims (17, 18, 19, 20)
