Abstract:
In recent years, mobile devices have rapidly penetrated into our daily lives. However, several drawbacks of mobile devices have been mentioned so far. The proposed system called Toss-It provides intuitive information transfer techniques for mobile devices, by fully utilizing their mobility. A user of Toss-It can send information from the user's PDA to other electronic devices with a toss or swing action, as the user would toss a ball or deal cards to others. This paper describes the current implementation of Toss-It and its user studies.
My Discussion:
The new idea for a method to quickly transfer data from one device to another is laid out well here, from the intital thinking and requirement, the work done to make a hardware implementations, all the way to a short user study. It is presented clearly, and quite clear then is also that this method as described comes with enormous problems for very many people in the population who do not have very accurate motor skills. While the issue of how intuitive it actually is to fling data from one device to another is not addressed -- is it for example something that users would come up with to try? How much visual or audio queueing does it require? -- the requirements of having to be able to fling data over one user to the user behind them in line-of-sight such that the person in the middle does not receive it puts a very big burden of accurate motion on the user. As their user studies point out, they cannot do it with any reliability of more than, on average, 70% using able-bodied users in a very controlled environment. If my Copy/Paste system only worked 7 out of 10 times in the best of conditions because I couldn't type in the exact right speed, I would probably Toss the system.
