The Tokyo Institute of Technology is working to improve touchscreen input with a range of haptic adapters. The adapters, which can be attaced to your thumb or held like a brush, look pretty straight forward and I wouldn’t be surprised if these went from research to production overnight.

The beauty of these adapters is in their simplicity. No fancy drivers, digitizers or batteries required.
