27. Hypothesis
“
Solutions designed for health-induced
impairments can be applied to situational-
induced impairments increasing the users’
performance, by assessing their capabilities
within real mobile contexts.

35. SIID Results
3 Walking conditions
seated, slow walking, normal walking (2 steps / sec)
3 Hand postures
one-hand/two-hand portrait; two-hand landscape
Major Results:
Error rate increases with mobility
Substitutions are the most common
error type (7%)
93% are due to poor aiming
Right-key substitution
36. HIID Procedure
Elderly
60 – 80 years old
Tremor disorders
Age related, Action tremor, Postural
tremor, Essential tremor
Characterize users’ tremor
Accelerometer, questionnaires, spiral
test, medical diagnosis
Larger screen sizes

Evaluation and Guidelines
40. Expected Results
1. Relationship between physical and
situational impairments
2. Guidelines to transfer solutions between
user groups
3. Transferability Index
41. Questions to the Consortium
Is this a valid approach (technology transfer)?
Should I develop novel solutions?
