VIDEO Interesting Touch Screen Lag Research

If you are moving your finger at 1 meter per second on an average 100 millisecond touch screen, your object will eventually become about 10 centimeters behind. At Microsoft Research, they have been trying to decrease the latency associated with touch screens. Albert Ng and Paul Dietz of the Applied Sciences Group explain what it will mean for artists and regular users to remove rubber banding by bringing about a 1 millisecond touch screen response time. Current tablets are compared with possibly faster ones in the future.



In the future, these systems will help your fingers feel like you are moving a real physical object. The video does not take into account sensitivity detection and vectoring - common issues on modern tablets and slates that are slowly being improved. For example, pushing down harder can result in a thicker response with a pen draw.

The video you referenced highlights the efforts made at Microsoft Research to reduce touch screen latency, aiming for a 1 millisecond touch screen response time. This significant decrease in latency from the typical 100 milliseconds could have profound implications for both artists and everyday users.
By achieving such low response times, devices can provide a more immersive and realistic interaction experience. Users would experience a near-instantaneous response to their touch inputs, making it feel as though they are manipulating physical objects directly. This advancement could revolutionize touchscreen interactions by making them feel more natural and instinctive.
While the video focuses on enhancing speed and responsiveness, it's worth noting that sensitivity detection and vectoring are also crucial aspects of touchscreen technology that impact user experience. These features play a vital role in capturing nuanced inputs, such as pressure variations or subtle movements, which are particularly important for activities like drawing with a stylus or pen.
The continuous improvement in these areas, including sensitivity detection and vectoring, contributes to making modern tablets and slates more versatile and user-friendly. By addressing these factors alongside reducing latency, future touchscreen devices have the potential to offer users a seamless and intuitive interaction experience that closely mimics physical interactions.
