Abstract
<p><span lang="EN-US"><span style="font-family: Gulim; font-size: medium;">Touch interface technologies for mobile devices are essentially in use. The purpose of such touch interfaces is to run an application by touching a screen with a user’s finger or to implement various functions on the device. When the user has an attempt to use the touch interface, users tend to grab the mobile device with one hand. Because of the existence of untouchable areas to which the user cannot reach with the user’s fingers, it is possible to occur for a case where the user is not able to touch a specific area on the screen accurately. This results in some issues that the mobile device does not carry out the user’s desired function and the execution time is delayed due to the wrong implementation. Therefore, there is a need to distinguish the area where the user can stably input the touch interface from the area where the users cannot and to overcome the problems of the unstable touch area. Furthermore, when the size of the screen increases, these issues will become more serious because of an increase in the unstable touch areas. Especially, an interface that receives position and force data like 3D-touch requires the stable area setting different from the conventional 2D-touch. In this paper, we search and analyze the stable touch areas on the large screen where the user can do 3D-touch inputs.</span></span></p>
Highlights
There has been a huge shift in smart device market in recent years, with the most notable sign of the sales of phablets, a compound word of phone and tablet
Direct comparison shows that the portion with the highest 2D-touch satisfaction is slightly wider than the portion with the 3D-touch
Because the screen of the smart device tends to be a rectangle, it is reasonable that we find a rectangle that buttons in that area should have a greater value than a given threshold
Summary
There has been a huge shift in smart device market in recent years, with the most notable sign of the sales of phablets, a compound word of phone and tablet. It seems to be natural that people required highly developed smart device with appropriate screen size and the phablets are the devices which satisfy their needs. As both the penetration of smart devices and the use of large-screen smart devices have grown, the importance of the touch interface, the most typical input method for smart devices, has increased. That implies 3D-touch interface has a huge advantage: using a function without running an application directly This trend is likely to increase the use of large screen smart devices based on 3Dtouch technology.
