Kim Randrup, Chairman of the Stockholm Stroke organisation tries new Tactsenze prototype



I met recently with Kim Randrup. Kim suffered a massive stroke 13 years ago which paralyzed his left side. He’s been determined and focused on his self-rehabilitation and has now regained most his coordination. It’s all about  motivation, he says.

Kim tested our Tactdance prototype which sends pre-programmed tactile impulses to the legs. Follow the impulse pattern which is matched to a salsa music beat and you can soon dance the salsa. That’s the idea, but it goes slowly for those who’ve had a stroke. Kim smiles as his legs sway back and forth. Could the Tactdance system become a complement to the usual rehab program for stroke sufferers?

”Of course!” says Kim.  ”Physical training is usually very boring. It assumes people are machines. Motivation is the most important key to success. Combining physical training through tactile stimulation in a music and dance program creates an enjoyable experience. I think with this we would become more motivated to continue to train, and to train more often.”

The Stockholm Stroke Organization will soon have a get together where members, all of them stroke sufferers will have a chance to test the Tactdance prototype and give us their comments and suggestions for its further development.



Lund Technical University cooperates on Tactdance project

Assistant Professor Charlotte Magnusson and I had been discussing Tactdance and its unique tactile communication system for awhile. In late August I met with Dr. Magnusson, a designer at the Ingvar Kamprad Design Center in Lund (part of Lund’s Technical University) where we agreed to work together to explore the possibilities for development of an advanced prototype. Dr. Magnusson is a non-visual interaction designer (movements, sense, hearing) employed by CERTEC, Sweden’s leading developer of technical aids for the functionally impaired.

We are now exploring both how to best proceed with the technical development of the present prototype and determine how, and for whom, the technique could be most beneficial.

Tactdance- a new tactile prototype

We just demonstrated our new prototype we call Tactdance to a delighted public at the KTH Open Labs Digital Mindset Playground. Our device generates tactile impulses to your body surface so you can learn to dance. We can also create tactile exercise programs to match the beats of the songs on your music playlist. While our primary goal is to aid the visually impaired and deaf-blind, anyone can enjoy this.

Tactsenze Displays at Int’l Tactile Reading Fair in Sweden


An International Tactile Exposition for Braille & Graphics for Children and Youth was held April 5-7th in Stockholm. Tactsenze had a stand where we displayed our new tactile communication device. Though we’re in the prototype stage, we’re moving forward toward a product for market. We had a great response, as many visually impaired participants tested our prototype, gasping ”wow”. Beside laughing as they were lightly tickled on their foot by the technique, those who tested the device provided valuable feedback. At the same time a number of textile communication researchers and their institutions came up to establish contact.

Meeting with Swedish National Organisations for Visually Impaired and Deaf-Blind

The Tactsenze project organized a meeting with:

  • NKCDB (Swedish National Knowledge Centre for the Deaf-Blind)
  • FSDB ( Swedish National Deaf-Blind Association),
  • MSM (Swedish  Gov’t  Agency for Accessible Media),
  • SRF (Swedish National Org. for the Visually Impaired),
  • SPSM (National Agency for Special Needs Education and Schools),

…as well as several visually impaired musicians. These are the authorities on the direction we should go with Tactsenze technique in future. They’re also the future customers of a product we develop. What a brainstorming session! Many ideas came forth and we’ll surely be meeting again to follow up.
