In this study, we focus on creating vibrotactile feedback on a touchscreen that simulates the feeling of physical buttons using piezo actuators attached to it. It is also difficult to relate the limited vibrotactile feedback generated by these motors to different types of physical buttons. Although mobile phones incorporate low-cost vibration motors to enhance touch-based interactions, it is not possible to generate complex tactile effects on touchscreens.
However, there is limited tactile feedback available for their digital counterparts displayed on touchscreens. Buttons have distinct response characteristics and are easily activated by touch. We use buttons daily to turn lights on, to call an elevator, to ring a doorbell, or even to turn on our mobile devices. Interaction with physical buttons is an essential part of our daily routine. The results showed that an appropriate number of stimulus patterns provided higher typing speed, higher typing efficiency, and lower error rate. A user study was conducted to evaluate the effectiveness of the multiple vibrotactile feedback. However, the number of stimulus patterns might also affect the typing performance. A set of highly discriminable vibration patterns was designed and associated with different regions of a virtual keyboard to help users to locate the right keys. The purpose of this study was to investigate the usability of multiple vibrotactile feedback patterns in an entire virtual QWERTY keyboard input. Most prior tactile keyboard research used single stimulus pattern, which was not enough to recognize different keys. However, typing on touchscreens usually lacks informative tactile feedback and anchoring references to locate the right keys, and thus requires more visual attention. With advances in information technology, people spend more time on touchscreen-based virtual keyboards than physical keyboards. Our statistical analysis showed that there exist at least three adjective pairs for which participants have rated two out of three digital buttons similar to their physical counterparts. All twenty participants rated the degree of their subjective feelings associated with each adjective for all the physical and digital buttons investigated in this study. In addition, we harvested seven adjective pairs from the participants expressing their perceptual feeling of pressing the physical buttons. In our experiment, participants were able to match the three digital buttons with their physical counterparts with a success rate of 83%. Finally, we conducted a threealternative forced choice (3AFC) experiment with twenty participants to explore whether the resultant stimulus is distinct and realistic. Then, a button-specific vibrotactile stimulus was generated for each button based on the recorded data. We first recorded and analyzed the force, acceleration, and voltage data from twelve participants interacting with three different physical buttons: latch, toggle, and push buttons. CCS CONCEPTS Īlthough mobile phones incorporate low-cost vibration motors to enhance touch-based interactions, it is not possible to generate complex tactile effects on their touchscreens. We discuss how these findings can inform the design of future in-air typing systems.
We report that, compared to constrained typing, unconstrained typing generates shorter (49 mm) and faster (764 mm/s) key-strokes with a high correlation of finger movement and that the HAND strategy group exhibits more dynamic key-strokes. We examine properties of finger kinematics, correlated movement of fingers, interrelation in consecutive key-strokes, and 3D distribution of key-stroke movements. We show that unconstrained typing movements differ substantively from previously observed constrained in-air typing movements and introduce a novel binary categorization of typing strategies: typists who use finger movements alone (FIN-GER) and those who combine finger movement with gross hand movement (HAND).

The script sets the appropriate registry key to define the channel and kicks off the Office Click to Run Update to pull the latest build.We empirically explore fundamental requirements for achieving VR in-air typing by observing the unconstrained eyes-free in-air typing of touch typists. I’ve written a quick PowerShell script to allow you to choose your Channel from a Menu.
