A Method for Rapid Measurement of Contrast Sensitivity on Mobile Touch-Screens
Touch-screen displays in cell phones and tablet computers are now pervasive, making them an attractive option for vision testing outside of the laboratory or clinic. Here we describe a novel method in which subjects use a finger swipe to indicate the transition from visible to invisible on a grating which is swept in both contrast and frequency. Because a single image can be swiped in about a s...

متن کاملImpaired contrast sensitivity in diabetic patients with and without retinopathy: a new technique for rapid assessment.
A simple technique is described for assessing the sensitivity of the human visual system to gratings at threshold contrast. The technique has advantages for clinical use in that it is (1) inexpensive, (2) quick to administer, (3) portable, and (4) relatively free from bias. Forty-two diabetic patients and 84 normal controls have been tested. Fifteen diabetic patients (6/20 with retinopathy and ...
متن کاملDesign of Scalable Collaborative Multi-touch Screens
In this work, we are exploring the architectural design (software, hardware, human factors) of large and scalable multi-touch screens. In contrast to desktop and notebook computers, the size and scale of multi-touch systems spans along a much wider range. Therefore, we have designed a flexible process that facilitates the simulation of several important parameters, such as multiple cameras and ...
متن کاملAudiotactile Feedback Design for Touch Screens
The use of touch sensitive displays and touch surfaces is just emerging and they are more and more replacing physical buttons. If a physical button is pressed, audio and tactile feedback confirms the successful operation. The loss of audiotactile feedback in touch sensitive interfaces might create higher input error rates and user dissatisfaction. Therefore the design and evaluation of suitable...
