Touchscreen testing techniques are described. In one or more implementations, a piece of conductor (e.g., metal) is positioned as proximal to a touchscreen device and the touchscreen device is tested by simulating a touch of a user. This technique may be utilized to perform a variety of different testing of a touchscreen device, such as to test latency and probabilistic latency. Additional techniques are also described including contact geometry testing techniques.

Contact geometry tests

Touchscreen testing techniques are described. In one or more implementations, a conductor is placed proximal to a touchscreen device and the touchscreen device is tested by simulating a touch of a user by placing the conductor in a grounded state and lack of a touch by the user by placing the conductor in an ungrounded state.

Probabilistic latency modeling

Latency measurement

A digital joystick operates in a digital mode or an analog emulation mode. In the digital mode, the joystick generates digital data indicating the position of a control stick and the status of buttons and transmits the digital data to the computer. The joystick may be coupled to the computer through a game port or a conventional interface port. Computer software operating within the computer can receive digital data directly from the joystick if it is operating in the digital mode. When in the analog emulation modes the joystick emulates resistances related to the position of the control stick. The emulated resistance data emulates the value of corresponding resistances in a conventional joystick. The resistance values may be derived from a programmable resistor, a programmable impedance, or a programmable current source. Multiplexers may also be used to couple the appropriate resistance value to the conventional game port input.

System and method for the software emulation of a computer joystick

A method and computer system present a user with a target icon on a computer screen and instruct the user to place a cursor thereon and twice actuate a mouse switch. The method measures the positions of the cursor on the screen during, and the time between, the two actuations by the user, and uses these measurements to customize, for the given user, the dual actuation speed and cursor movement area used to determine a double-click input command.
